When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your computer’s operating system may use a different
standard of measurement and report a lower capacity. In addition, some of the listed capacity is used for formatting and other functions, and thus will not be available for data storage.
Actual quantities will vary based on various factors, including file size, file format, features and application software. Actual data rates may vary depending on operating environment
and other factors. The export or re-export of hardware or software containing encryption may be regulated by the U.S. Department of Commerce, Bureau of Industry and Security (for
more information, visit www.bis.doc.gov), and controlled for import and use outside of the U.S. Seagate reserves the right to change, without notice, product offerings or specifications.

Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 13
3.0 General description
Seagate® Enterprise Performance 10K HDD v8 drives provide high performance, high capacity data storage for a variety of systems
including engineering workstations, network servers, mainframes, and supercomputers. The Serial Attached SCSI interface is
designed to meet next-generation computing demands for performance, scalability, flexibility and high-density storage
requirements.
The TurboBoost functionality provides improved performance over standard HDDs in real-world workloads. This improvement is due
to the addition of a solid state component that caches “hot” data for reads as well as protects write data via non-volatile cache (NVC).
Seagate Enterprise Performance 10K HDD drives are random access storage devices designed to support the Serial Attached SCSI
Protocol as described in the ANSI specifications, this document, and the SAS Interface Manual (part number 100293071) which
describes the general interface characteristics of this drive. Seagate Enterprise Performance 10K HDD drives are classified as
intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard. The SAS connectors, cables
and electrical interface are compatible with Serial ATA (SATA), giving future users the choice of populating their systems with either
SAS or SATA hard disk drives. This allows integrators to continue to leverage existing investment in SCSI while gaining a 12Gb/s serial
data transfer rate.
Seagate Enterprise Performance 10K HDD drives use a dedicated load/unload zone at the outermost radius of the media to eliminate
the possibility of destroying or degrading data by landing in the data zone. The heads automatically go to the ramp load/unload
when power is removed from the drive and during the deeper sleep modes.
An automatic shipping lock prevents potential damage to the heads and discs that results from movement during shipping and
handling. The shipping lock disengages and the head load process begins when power is applied to the drive.
The drives also use a high-performance actuator assembly with a low-inertia, balanced, patented, straight arm design that provides
excellent performance with minimal power dissipation in any orientation.
3.1 Standard features
Enterprise Performance 10K HDD drives have the following standard features:

native drives and 4096, 4160, 4192, and 4224 for 4096 native drives. Users having the necessary equipment may modify the data
block size before issuing a format command and obtain different formatted capacities than those listed.
To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate
recommends product planning in one of two modes:
Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will meet. We
recommend customers use this capacity in their project planning, as it ensures a stable operating point with backward and forward
compatibility from generation to generation. The current guaranteed operating points for this product are shown below.
NOTE There is no significant performance difference between Self-Encrypting
Drive and standard (non-Self-Encrypting Drive) models.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 15
3.5 Programmable drive capacity
Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select (6)
parameter list table in the SAS Interface Manual, part number 100293071. A value of zero in the Number of Blocks field indicates that
the drive will not change the capacity it is currently formatted to have. A number other than zero and less than the maximum
number of LBAs in the Number of Blocks field changes the total drive capacity to the value in the Number of Blocks field. A value
greater than the maximum number of LBAs is rounded down to the maximum capacity.
3.6 Factory-installed options
The following items may be ordered which are incorporated at the manufacturing facility during production or packaged before
shipping. Some of the options available are (not an exhaustive list of possible options):
• Other capacities can be ordered depending on sparing scheme and sector size requested.
• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection against transit dam-
age. Units shipped individually require additional protection as provided by the single unit shipping pack. Users planning single
unit distribution should specify this option.
•The Safety and Regulatory Agency Specifications, part number 75789512, is usually included with each standard OEM drive shipped,
but extra copies may be ordered.

4.2.2 General performance characteristics
4.3 Start/stop time
The drive accepts the commands listed in the SAS Interface Manual less than 3 seconds after DC power has been applied.
If the drive receives a NOTIFY (ENABLE SPINUP) primitive through either port and has not received a START STOP UNIT command with
the START bit equal to 0, the drive becomes ready for normal operations within 20 seconds (excluding the error recovery procedure).
If the drive receives a START STOP UNIT command with the START bit equal to 0 before receiving a NOTIFY (ENABLE SPINUP)
primitive, the drive waits for a START STOP UNIT command with the START bit equal to 1. After receiving a START STOP UNIT
command with the START bit equal to 1, the drive waits for a NOTIFY (ENABLE SPINUP) primitive. After receiving a NOTIFY (ENABLE
SPINUP) primitive through either port, the drive becomes ready for normal operations within 20 seconds (excluding the error
recovery procedure).
If the drive receives a START STOP UNIT command with the START bit and IMMED bit equal to 1 and does not receive a NOTIFY
(ENABLE SPINUP) primitive within 5 seconds, the drive fails the START STOP UNIT command.
The START STOP UNIT command may be used to command the drive to stop the spindle. Stop time is 20 seconds (maximum) from
removal of DC power. SCSI stop time is 20 seconds. There is no power control switch on the drive. However, power can be cycled on
the drive by utilizing SAS Power Disable feature defined by T10 (i.e. drive Pin 3 high).
4.4 Prefetch/multi-segmented cache control
The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance
system performance. Cache refers to the drive buffer storage space when it is used in cache operations. To select this feature, the
host sends the Mode Select command with the proper values in the applicable bytes in page 08h. Prefetch and cache operations are
independent features from the standpoint that each is enabled and disabled independently using the Mode Select command;
however, in actual operation, the prefetch feature overlaps cache operation somewhat as described in sections 4.5.1 and 4.5.2.
All default cache and prefetch mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are given in
Section 11.3.2.

Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 18
4.5 Cache operation
Note. Refer to the SAS Interface Manual for more detail concerning the cache bits.
Of the 128MB physical buffer space in the drive, approximately 60,000KB are available as a data cache. The remaining buffer space is
reserved for internal drive use.
The drive keeps track of the logical block addresses of the data stored in each segment of the buffer. If the cache is enabled (see RCD
bit in the SAS Interface Manual ), data requested by the host with a read command is retrieved from the buffer, if possible, before any
disk access is initiated. If cache operation is not enabled, the buffer is still used, but only as circular buffer segments during disk
medium read operations (disregarding Prefetch operation for the moment). That is, the drive does not check in the buffer segments
for the requested read data, but goes directly to the medium to retrieve it. The retrieved data merely passes through some buffer
segment on the way to the host. All data transfers to the host are in accordance with buffer-full ratio rules. See the explanation
provided with the information about Mode Page 02h (disconnect/reconnect control) in the SAS Interface Manual.
The following is a simplified description of the prefetch/cache operation:
Case A—read command is received and all of the requested logical blocks are already in the cache:
1. Drive transfers the requested logical blocks to the initiator.
Case B—A Read command requests data, and at least one requested logical block is not in any segment of the cache:
1. The drive fetches the requested logical blocks from the disk and transfers them into a segment, and then from there to the host
in accordance with the Mode Select Disconnect/Reconnect parameters, page 02h.
2. If the prefetch feature is enabled, refer to section 4.5.2 for operation from this point.
Each cache segment is actually a self-contained circular buffer whose length is an integer number of logical blocks. The drive
dynamically creates and removes segments based on the workload. The wrap-around capability of the individual segments greatly
enhances the cache’s overall performance.
4.5.1 Caching write data
Write caching is a write operation by the drive that makes use of a drive buffer storage area where the data to be written to the
medium is stored while the drive performs the Write command.
NOTE
The size of each segment is not reported by Mode Sense command page 08h, bytes 14 and 15. The value 0XFFFF
is always reported regardless of the actual size of the segment. Sending a size specification using the Mode Select
command (bytes 14 and 15) does not set up a new segment size. If the STRICT bit in Mode page 00h (byte 2, bit 1)
is set to one, the drive responds as it does for any attempt to change an unchangeable parameter.
NOTE Write caching in this section is the traditional SCSI write caching (WCE=1) where writes are not protected on
power loss. TurboBoost provides NVC-protected write caching when WCE=0 over a portion of the DRAM.
NOTE Refer to the SAS Interface Manual for more detail concerning the cache bits.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 19
If read caching is enabled (RCD=0), then data written to the medium is retained in the cache to be made available for future read
cache hits. The same buffer space and segmentation is used as set up for read functions. The buffer segmentation scheme is set up or
changed independently, having nothing to do with the state of RCD. When a write command is issued, if RCD=0, the cache is first
checked to see if any logical blocks that are to be written are already stored in the cache from a previous read or write command. If
there are, the respective cache segments are cleared. The new data is cached for subsequent Read commands.
If the number of write data logical blocks exceed the size of the segment being written into, when the end of the segment is reached,
the data is written into the beginning of the same cache segment, overwriting the data that was written there at the beginning of
the operation; however, the drive does not overwrite data that has not yet been written to the medium.
If write caching is enabled (WCE=1), then the drive may return Good status on a write command after the data has been transferred
into the cache, but before the data has been written to the medium. If an error occurs while writing the data to the medium, and
Good status has already been returned, a deferred error will be generated.
The Synchronize Cache command may be used to force the drive to write all cached write data to the medium. Upon completion of a
Synchronize Cache command, all data received from previous write commands will have been written to the medium. Section 11.3.2
shows the mode default settings for the drive.
4.5.2 Prefetch operation
If the Prefetch feature is enabled, data in contiguous logical blocks on the disk immediately beyond that which was requested by a
Read command are retrieved and stored in the buffer for immediate transfer from the buffer to the host on subsequent Read
commands that request those logical blocks (this is true even if cache operation is disabled). Though the prefetch operation uses the
buffer as a cache, finding the requested data in the buffer is a prefetch hit, not a cache operation hit.
To enable Prefetch, use Mode Select page 08h, byte 12, bit 5 (Disable Read Ahead - DRA bit). DRA bit = 0 enables prefetch.
The drive does not use the Max Prefetch field (bytes 8 and 9) or the Prefetch Ceiling field (bytes 10 and 11).
When prefetch (read look-ahead) is enabled (enabled by DRA = 0), the drive enables prefetch of contiguous blocks from the disk
when it senses that a prefetch hit will likely occur. The drive disables prefetch when it decides that a prefetch hit is not likely to occur.
4.5.3 TurboBoost caching operations
Read data that has been promoted into the TurboBoost read cache does not persist through a power cycle. Read data is retrieved
from the rotating media after a power cycle.
When WCE=0, TurboBoost provides NVC-protected write caching over the portion of the DRAM used to coalesce writes. Write data
only goes into NVC when there is an unexpected power loss to the drive. The NVC has 90-day data retention. When WCE=1, a
TurboBoost drive will operate on writes like a standard drive–writes in cache are not protected by NVC and may be lost with power
loss.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 20
5.0 Reliability specifications
The following reliability specifications assume correct host and drive operational interface, including all interface timings, power
supply voltages, environmental requirements and drive mounting constraints.
5.1 Error rates
The error rates stated in this manual assume the following:
• The drive is operated in accordance with this manual using DC power as defined in paragraph 6.3, "DC power consumption."
• Errors caused by host system failures are excluded from error rate computations.
• Assume random data.
• Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write retries and full retry time.
5.1.1 Recoverable Errors
Recoverable errors are those detected and corrected by the drive, and do not require user intervention.
Recoverable Data errors will use Error Correction when needed.
Recovered Data error rate is determined using read bits transferred for recoverable errors occurring during a read, and using write
bits transferred for recoverable errors occurring during a write.
5.1.2 Unrecoverable Errors
An unrecoverable data error is defined as a failure of the drive to recover data from the media. These errors occur due to head/media
or write problems. Unrecoverable data errors are only detected during read operations, but not caused by the read. If an
unrecoverable data error is detected, a MEDIUM ERROR (03h) in the Sense Key will be reported. Multiple unrecoverable data errors
resulting from the same cause are treated as 1 error.
5.1.3 Seek errors
A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek error, the
drive automatically performs an error recovery process. If the error recovery process fails, a seek positioning error (Error code = 15h
or 02h) will be reported with a Hardware error (04h) in the Sense Key. Recoverable seek errors are specified at Less than 10 errors in
108 seeks. Unrecoverable seek errors (Sense Key = 04h) are classified as drive failures.
5.1.4 Interface errors
An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port connected to
the receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or CRC error.
5.2 Reliability and service
The reliability of Seagate Enterprise Performance 10K HDD disk drives can be enhanced by ensuring that the drive receives adequate
cooling. Section 6.0 provides temperature measurements and other information that may be used to enhance the service life of the
drive. Section 10.2 provides recommended air-flow information.
Seek error rate: Less than 10 errors in 108 seeks
Read Error Rates1
1. Error rate specified with automatic retries and data correction with ECC enabled and all flaws reallocated.
Recovered Data Less than 10 error in 1012 bits transferred (OEM default settings)
Unrecovered Data Less than 1 sector in 1016 bits transferred
Miscorrected Data Less than 1 sector in 1021 bits transferred
Interface error rate: Less than 1 error in 1012 bits transferred
Mean Time Between Failure (MTBF): 2,000,000 hours
Annualized Failure Rate (AFR): 0.44%
Preventive maintenance: None required
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 21
5.2.1 Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF)
The production disk drive shall achieve an annualized failure-rate of 0.44% (MTBF of 2,000,000 hours) over a 5 year service life when
used in Enterprise Storage field conditions as limited by the following:
• 8760 power-on hours per year.
• HDA temperature as reported by the drive <= 50°C
• Ambient wet bulb temp <= 26°C
•Typical workload
• The AFR (MTBF) is a population statistic not relevant to individual units.
• ANSI/ISA S71.04-2013 G2 classification levels and dust contamination to ISO 14644-1 Class 8 standards (as measured at the
device)
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal drive temperature and
humidity. Occasional excursions in operating conditions between the rated MTBF conditions and the maximum drive operating
conditions may occur without significant impact to the rated MTBF. However continual or sustained operation beyond the rated
MTBF conditions will degrade the drive MTBF and reduce product reliability.
5.2.2 Preventive maintenance
No routine scheduled preventive maintenance is required.
5.2.3 Hot plugging the drive
When a disk is powered on by switching the power or hot plugged, the drive runs a self test before attempting to communicate on
its’ interfaces. When the self test completes successfully, the drive initiates a Link Reset starting with OOB. An attached device should
respond to the link reset. If the link reset attempt fails, or any time the drive looses sync, the drive initiated link reset. The drive will
initiate link reset once per second but alternates between port A and B. Therefore each port will attempt a link reset once per 2
seconds assuming both ports are out of sync.
If the self-test fails, the drive does not respond to link reset on the failing port.
5.2.4 S.M.A.R.T.
S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize conditions
that indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow an application to back up the
data before an actual failure occurs.
Each monitored attribute has been selected to monitor a specific set of failure conditions in the operating performance of the drive
and the thresholds are optimized to minimize “false” and “failed” predictions.
NOTE
It is the responsibility of the systems integrator to assure that no temperature, energy, voltage hazard,
shorting of PCBA to ground, or ESD potential hazard is presented during the hot connect/disconnect
operation. Discharge the static electricity from the drive carrier prior to inserting it into the system.
CAUTION The drive motor must come to a complete stop prior to changing
the plane of operation. This time is required to insure data integrity.
NOTE The drive’s firmware monitors specific attributes for degradation
over time but can’t predict instantaneous drive failures.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 22
Controlling S.M.A.R.T.
The operating mode of S.M.A.R.T. is controlled by the DEXCPT and PERF bits on the Informational Exceptions Control mode page
(1Ch). Use the DEXCPT bit to enable or disable the S.M.A.R.T. feature. Setting the DEXCPT bit disables all S.M.A.R.T. functions. When
enabled, S.M.A.R.T. collects on-line data as the drive performs normal read and write operations. When the PERF bit is set, the drive is
considered to be in “On-line Mode Only” and will not perform off-line functions.
Applications can measure off-line attributes and force the drive to save the data by using the Rezero Unit command. Forcing
S.M.A.R.T. resets the timer so that the next scheduled interrupt is in one hour.
Applications can interrogate the drive through the host to determine the time remaining before the next scheduled measurement
and data logging process occurs. To accomplish this, issue a Log Sense command to log page 0x3E. This allows applications to
control when S.M.A.R.T. interruptions occur. Forcing S.M.A.R.T. with the RTZ command resets the timer.
Performance impact
S.M.A.R.T. attribute data is saved to the disk so that the events that caused a predictive failure can be recreated. The drive measures
and saves parameters once every hour subject to an idle period on the drive interfaces. The process of measuring off-line attribute
data and saving data to the disk is interruptable. The maximum on-line only processing delay is summarized below
Reporting control
Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to the reporting method.
For example, if the MRIE is set to one, the firmware will issue to the host an 01-5D00 sense code. The FRU field contains the type of
predictive failure that occurred. The error code is preserved through bus resets and power cycles.
Determining rate
S.M.A.R.T. monitors the rate at which errors occur and signals a predictive failure if the rate of degraded errors increases to an
unacceptable level. To determine rate, error events are logged and compared to the number of total operations for a given attribute.
The interval defines the number of operations over which to measure the rate. The counter that keeps track of the current number of
operations is referred to as the Interval Counter.
S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of the number of errors for
the current interval. This counter is referred to as the Failure Counter.
Error rate is the number of errors per operation. The algorithm that S.M.A.R.T. uses to record rates of error is to set thresholds for the
number of errors and their interval. If the number of errors exceeds the threshold before the interval expires, the error rate is
considered to be unacceptable. If the number of errors does not exceed the threshold before the interval expires, the error rate is
considered to be acceptable. In either case, the interval and failure counters are reset and the process starts over.

DEXCPT = 0
S.M.A.R.T. delay times 75 ms
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 23
Predictive failures
S.M.A.R.T. signals predictive failures when the drive is performing unacceptably for a period of time. The firmware keeps a running
count of the number of times the error rate for each attribute is unacceptable. To accomplish this, a counter is incremented each time
the error rate is unacceptable and decremented (not to exceed zero) whenever the error rate is acceptable. If the counter continually
increments such that it reaches the predictive threshold, a predictive failure is signaled. This counter is referred to as the Failure
History Counter. There is a separate Failure History Counter for each attribute.
5.2.5 Thermal monitor
Seagate Enterprise Performance 10K HDD drives implement a temperature warning system which:
1. Signals the host if the temperature exceeds a value which would threaten the drive.
2. Saves a S.M.A.R.T. data frame on the drive which exceeds the threatening temperature value.
A temperature sensor monitors the drive temperature and issues a warning over the interface when the temperature exceeds a set
threshold. The temperature is measured at power-up and then at ten-minute intervals after power-up.
The thermal monitor system generates a warning code of 01-0B01 when the temperature exceeds the specified limit in compliance
with the SCSI standard.
This feature is controlled by the Enable Warning (EWasc) bit, and the reporting mechanism is controlled by the Method of Reporting
Informational Exceptions field (MRIE) on the Informational Exceptions Control (IEC) mode page (1Ch).
5.2.6 Drive Self Test (DST)
Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST validates
the functionality of the drive at a system level.
There are two test coverage options implemented in DST:
1. Extended test
2. Short test
The most thorough option is the extended test that performs various tests on the drive and scans every logical block address (LBA) of
the drive. The short test is time-restricted and limited in length—it does not scan the entire media surface, but does some
fundamental tests and scans portions of the media.
If DST encounters an error during either of these tests, it reports a fault condition. If the drive fails the test, remove it from service and
return it to Seagate for service.
5.2.6.1 DST failure definition
The drive will present a “diagnostic failed” condition through the self-tests results value of the diagnostic log page if a functional
failure is encountered during DST. The channel and servo parameters are not modified to test the drive more stringently, and the
number of retries are not reduced. All retries and recovery processes are enabled during the test. If data is recoverable, no failure
condition will be reported regardless of the number of retries required to recover the data.
The following conditions are considered DST failure conditions:
• Seek error after retries are exhausted
• Track-follow error after retries are exhausted
• Read error after retries are exhausted
• Write error after retries are exhausted
Recovered errors will not be reported as diagnostic failures.

This section provides all of the information necessary to implement the DST function on this drive.
5.2.6.2.1 State of the drive prior to testing
The drive must be in a ready state before issuing the Send Diagnostic command. There are multiple reasons why a drive may not be
ready, some of which are valid conditions, and not errors. For example, a drive may be in process of doing a format, or another DST. It
is the responsibility of the host application to determine the “not ready” cause.
While not technically part of DST, a Not Ready condition also qualifies the drive to be returned to Seagate as a failed drive.
A Drive Not Ready condition is reported by the drive under the following conditions:
• Motor will not spin
• Motor will not lock to speed
• Servo will not lock on track
• Drive cannot read configuration tables from the disk
In these conditions, the drive responds to a Test Unit Ready command with an 02/04/00 or 02/04/03 code.
5.2.6.2.2 Invoking DST
To invoke DST, submit the Send Diagnostic command with the appropriate Function Code (001b for the short test or 010b for the
extended test) in bytes 1, bits 5, 6, and 7.
5.2.6.2.3 Short and extended tests
DST has two testing options:
1. short
2. extended
These testing options are described in the following two subsections.
Each test consists of three segments: an electrical test segment, a servo test segment, and a read/verify scan segment.
Short test (Function Code: 001b)
The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds. The
short test does not scan the entire media surface, but does some fundamental tests and scans portions of the media. A complete
read/verify scan is not performed and only factual failures will report a fault condition. This option provides a quick confidence test of
the drive.
Extended test (Function Code: 010b)
The objective of the extended test option is to empirically test critical drive components. For example, the seek tests and on-track
operations test the positioning mechanism. The read operation tests the read head element and the media surface. The write
element is tested through read/write/read operations. The integrity of the media is checked through a read/verify scan of the media.
Motor functionality is tested by default as a part of these tests.
The anticipated length of the Extended test is reported through the Control Mode page.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 25
5.2.6.2.4 Log page entries
When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created by inserting a new self-
test parameter block at the beginning of the self-test results log parameter section of the log page. Existing data will be moved to
make room for the new parameter block. The drive reports 20 parameter blocks in the log page. If there are more than 20 parameter
blocks, the least recent parameter block will be deleted. The new parameter block will be initialized as follows:
1. The Function Code field is set to the same value as sent in the DST command
2. The Self-Test Results Value field is set to Fh
3. The drive will store the log page to non-volatile memory
After a self-test is complete or has been aborted, the drive updates the Self-Test Results Value field in its Self-Test Results Log page in
non-volatile memory. The host may use Log Sense to read the results from up to the last 20 self-tests performed by the drive. The
self-test results value is a 4-bit field that reports the results of the test. If the field is set to zero, the drive passed with no errors
detected by the DST. If the field is not set to zero, the test failed for the reason reported in the field.
The drive will report the failure condition and LBA (if applicable) in the Self-test Results Log parameter. The Sense key, ASC, ASCQ,
and FRU are used to report the failure condition.
5.2.6.2.5 Abort
There are multiple ways to abort a diagnostic. Two examples are: using a SCSI Bus Reset or a Bus Device message to abort the
diagnostic
To abort a DST executing in background mode, use the abort code in the DST Function Code field. This will cause a 01 (self-test
aborted by the application client) code to appear in the self-test results values log. All other abort mechanisms will be reported as a
02 (self-test routine was interrupted by a reset condition).
5.2.7 Product warranty
See “Seagate® Technology Support Services” on page 7. for warranty contact information.
Shipping
When transporting or shipping a drive, use only a Seagate-approved container. Keep the original box. Seagate approved containers
are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the drive warranty.
Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in transit. Contact an
authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping by an air-ride carrier experienced in
handling computer equipment.
Storage
The maximum recommended storage period for the drive in a non-operational environment is 90 days. Drives should be stored in
the original unopened Seagate shipping packaging when ever possible. Once the drive is removed from the Seagate original
packaging the recommended maximum period between drive operation cycles is 30 days. During any storage period the drive non-
operational temperature, humidity, wet bulb, atmospheric conditions, shock, vibration, magnetic and electrical field specifications
should be followed.
Product repair and return information
Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does not sanction any third-
party repair facilities. Any unauthorized repair or tampering with the factory seal voids the warranty.

6.0 Physical/electrical specifications
This section provides information relating to the physical and electrical characteristics of the drive.
6.1 PowerChoiceTM power management
Drives using the load/unload architecture provide programmable power management to tailor systems for performance and greater
energy efficiency.
The table below lists the supported PowerChoice modes. The further down in the table, the more power savings can be realized. For
example, Idle_B mode results in greater power savings than Idle_A mode. Standby modes results in the greatest power savings.
PowerChoice modes
PowerChoiceTM can be invoked using one of these two methods:
• Power Condition mode page method—Enable and initialize the idle condition timers and/or the standby condition timers. The
timer values are based on the values set in the Power Condition mode page.
• START STOP UNIT command method—Use the START STOP UNIT command (OPERATION CODE 1Bh). This allows the host to
directly transition the drive to any supported PowerChoice mode.
If both the Power Condition mode page and START STOP UNIT command methods are used, the START STOP UNIT command request
takes precedence over the Power Condition mode page power control and may disable the idle condition and standby condition
timers. The REQUEST SENSE command reports the current PowerChoice state if active and also the method by which the drive
entered the PowerChoice state.
When the drive receives a command, all power condition timers are suspended if they were enabled via the Power Condition mode
page. Once all outstanding commands are processed, the power condition timers are reinitialized to the values defined in the Power
Condition mode page.
Mode Description
Idle_A Reduced electronics
Idle_B Heads unloaded. Disks spinning at full RPM
Idle_C Heads unloaded. Disks spinning at reduced RPM
Standby_Y Heads unloaded. Disks spinning at reduced RPM
Standby_Z Heads unloaded. Motor stopped (disks not spinning)
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 27
6.1.1 PowerChoice reporting methods
PowerChoiceTM provides these reporting methods for tracking purposes:
Request Sense command reports
• Current power condition
• Method of entry
Note. Processing the Request Sense command does not impact the drive’s power save state.
Mode Sense command reports (mode page 0x1A)
• Idle conditions enabled / disabled
• Idle condition timer values (100ms increments) (default, saved, current, changeable)
Power Condition Vital Product Data (VPD) Page (VPD page 0x8A)
• Supported power conditions
• Typical recovery time from power conditions (1ms increments)
Start/Stop Cycle Counter Log Page reports (log page 0x0E)
• Specified and accumulated Start/Stops and Load/Unload cycles
Power Condition Transitions Log Page reports (log page 0x1A, subpage 0x00)
• Accumulated transitions to Active, Idle_A, Idle_B, Idle_C, Standby_Y, Standby_Z
6.2 AC power consumption
None.
6.3 DC power consumption
The DC current measurements below are based on an average of drives tested under nominal operating conditions using 5V and 12V
input voltage at the drive interface connector.
Standard and SED drive models have identical hardware, however the encryption block of the controller ASIC is active for SED
models. This represents a small additional current draw on the 5V supply of about 30mA. There is no additional current draw on the
12V supply.
Operation at 6.0Gb mode reduces the +5V supply load by 15mA with a commensurate power reduction of 75mW.
NOTE There is no measurable impact to the 12V supply load when running at lower interface speeds.

[1] Measured with average reading DC ammeter. Instantaneous +12V current peaks will exceed these values. Power supply at nominal voltage. N
(number of drives tested) = 6, 35 Degrees C ambient.
[2] For +12 V, a -10% tolerance is allowed during initial spindle start but must return to ±5% before reaching 9,936 RPM. The ±5% must be main-
tained after the drive signifies that its power-up sequence has been completed and that the drive is able to accept selection by the host initia-
tor.
[3] See +12V current profile in Figure 1 (for 1200GB models).
[4] This condition occurs after OOB and Speed Negotiation completes but before the drive has received the Notify Spinup primitive.
[5] See paragraph 6.3.1, "Conducted noise immunity." Specified voltage tolerance includes, noise, and transient response.
[6] Operating condition is defined as random 8 block reads.
[7] During idle, the drive heads are relocated every 30 seconds to a random location within the band from three-quarters to maximum track.

General DC power consumption notes.
1. Minimum current loading for each supply voltage is not less than 1.7% of the maximum operating current shown.
2. The +5V and +12V supplies should employ separate ground returns.
3. Where power is provided to multiple drives from a common supply, careful consideration for individual drive power consump-
tion should be noted. Where multiple units are powered on simultaneously, the peak starting current must be available to each
device.
4. Parameters, other than spindle start, are measured after a 10-minute warm up.
5. No terminator power.
6.3.1 Conducted noise immunity
Noise is specified as a periodic and random distribution of frequencies covering a defined frequency range. Maximum allowed noise
values given below are peak-to-peak measurements and apply at the drive power connector.
6.3.2 Power sequencing
The drive does not require power sequencing. The drive protects against inadvertent writing during power-up and down.
6.3.3 Current profiles
The +12V and +5V current profiles for the Enterprise Performance 10K HDD drives are shown below.

stabilize, read drive temperature from Temperature Log Page (0Dh).
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 39
6.5.4 Shock and vibration
Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is installed in an
enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur internally to the enclosure resulting in
drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the enclosure to minimize
drive movement.
The limits of shock and vibration defined within this document are specified with the drive mounted by any of the four methods
shown in Figure 9, and in accordance with the restrictions of Section 10.3.
6.5.4.1 Shock
a. Operating
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding:
• 40 Gs at a maximum duration of 11ms (half sinewave)
• 25 Gs at a maximum duration of 2ms (half sinewave)
Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.
b. Non-operating
The limits of non-operating shock shall apply to all conditions of handling and transportation. This includes both isolated drives
and integrated drives.
The drive subjected to nonrepetitive shock not exceeding the three values below, shall not exhibit device damage or perfor-
mance degradation.
• 80 Gs at a maximum duration of 11ms (half sinewave)
• 400 Gs at a maximum duration of 2ms (half sinewave)
• 300 Gs at a maximum duration of 0.5ms (half sinewave)
Shock may be applied in the X, Y, or Z axis.
c. Packaged
Seagate finished drive bulk packs are designed and tested to meet or exceed applicable ISTA and ASTM standards. Volume fin-
ished drives will be shipped from Seagate factories on pallets to minimize freight costs and ease material handling. Seagate fin-
ished drive bulk packs may be shipped individually. For less than full shipments, instructions are printed on the bulk pack carton
for minimum drive quantities and proper drive placement.

Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 40
6.5.4.2 Vibration
a. Operating—normal
The drive as installed for normal operation, shall comply with the complete specified performance while subjected to continuous
vibration not exceeding
5-500 Hz @ 0.5 G (zero to peak)
Vibration may be applied in the X, Y, or Z axis.
Operating normal translational random flat profile
10 - 500 Hz (translational random flat profile) 0.5 GRMS
b. Non-operating
The limits of non-operating vibration shall apply to all conditions of handling and transportation. This includes both isolated
drives and integrated drives.
The drive shall not incur physical damage or degraded performance as a result of continuous vibration not exceeding
5-500 Hz @ 3.0 G (zero to peak)
Vibration may be applied in the X, Y, or Z axis.
Non-operating translational random flat profile
10 - 500 Hz (translational random flat profile) 2.4 GRMS
6.5.5 Air cleanliness
The drive is designed to operate in a typical office environment with minimal environmental control.
6.5.6 Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial
environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing
cannot duplicate every potential application environment.
Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as
electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold films used
in hard disk drives are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the
most damaging. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be
minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with
sulfide-free alternatives.
Seagate recommends that data centers be kept clean by monitoring and controlling the dust and gaseous contamination. Gaseous
contamination should be within ANSI/ISA S71.04-2013 G2 classification levels (as measured on copper and silver coupons), and dust
contamination to ISO 14644-1 Class 8 standards, and MTBF rated conditions as defined in the Annualized Failure Rate (AFR) and
Mean Time Between Failure (MTBF) section.
6.5.7 Acoustics
Sound power during idle mode shall be 3.1 bels typical when measured to ISO 7779 specification.
There will not be any discrete tones more than 9 dB above the masking noise on typical drives when measured according to Seagate
specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive.
6.5.8 Electromagnetic susceptibility

7.0 About FIPS
The Federal Information Processing Standard (FIPS) Publication 140-2 is a U.S. Government Computer Security Standard used to
accredit cryptographic modules. It is titled 'Security Requirements for Cryptographic Modules (FIPS PUB 140-2)' and is issued by the
National Institute of Standards and Technology (NIST).
Purpose
This standard specifies the security requirements that will be satisfied by a cryptographic module utilized within a security system
protecting sensitive but unclassified information. The standard provides four increasing, qualitative levels of security: Level 1, Level 2,
Level 3 and Level 4. These levels are intended to cover the wide range of potential applications and environments in which
cryptographic modules may be employed.
Validation Program
Products that claim conformance to this standard are validated by the Cryptographic Module Validation Program (CMVP) which is a
joint effort between National Institute of Standards and Technology (NIST) and the Communications Security Establishment (CSE) of
the Government of Canada. Products validated as conforming to FIPS 140-2 are accepted by the Federal agencies of both countries
for the protection of sensitive information (United States) or Designated Information (Canada).
In the CMVP, vendors of cryptographic modules use independent, accredited testing laboratories to have their modules tested.
National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratories perform cryptographic module compliance/
conformance testing.
Seagate Enterprise SED
The SEDs referenced in this Product Manual have been validated by CMVP and have been thoroughly tested by a NVLAP accredited
lab to satisfy FIPS 140-2 Level 2 requirements. In order to operate in FIPS Approved Mode of Operation, these SEDs require security
initialization. For more information, refer to 'Security Rules' section in the 'Security Policy' document uploaded on the NIST website.
To reference the product certification visit - http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/1401vend.htm, and search for
“Seagate”.
Security Level 2
Security Level 2 enhances the physical security mechanisms of a Security Level 1 cryptographic module by adding the require-
ment for tamper-evidence, which includes the use of tamper-evident coatings or seals on removable covers of the module. Tam-
per-evident coatings or seals are placed on a cryptographic module so that the coating or seal must be broken to attain physical
access to the critical security parameters (CSP) within the module. Tamper-evident seals (example shown in Figure 11, page 42) are
placed on covers to protect against unauthorized physical access. In addition Security Level 2 requires, at a minimum, role-based
authentication in which a cryptographic module authenticates the authorization of an operator to assume a specific role and per-
form a corresponding set of services.

8.0 About self-encrypting drives
Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as
“protection of data at rest.” These drives are compliant with the Trusted Computing Group (TCG) Enterprise Storage Specifications as
detailed in Section 2.4.
The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital
communications industry. Seagate’s SED models comply with the standards published by the TCG.
To use the security features in the drive, the host must be capable of constructing and issuing the following two SCSI commands:
• Security Protocol Out
• Security Protocol In
These commands are used to convey the TCG protocol to and from the drive in their command payloads.
8.1 Data encryption
Encrypting drives use one inline encryption engine for each port, employing AES 256-bit data encryption keys with AES-XTS mode to
encrypt all data prior to being written on the media and to decrypt all data as it is read from the media. The encryption engines are
always in operation and cannot be disabled.
The 32-byte Data Encryption Key (DEK) is a random number which is generated by the drive, never leaves the drive, and is
inaccessible to the host system. The DEK is itself encrypted when it is stored on the media and when it is in volatile temporary
storage (DRAM) external to the encryption engine. A unique data encryption key is used for each of the drive's possible16 data bands
(see Section 8.5).
8.2 Controlled access
The drive has two security providers (SPs) called the "Admin SP" and the "Locking SP”. These act as gatekeepers to the drive security
services. Security-related commands will not be accepted unless they also supply the correct credentials to prove the requester is
authorized to perform the command.
8.2.1 Admin SP
The Admin SP allows the drive's owner to enable or disable firmware download operations (see Section 8.4). Access to the Admin SP
is available using the SID (Secure ID) password or the MSID (Manufacturers Secure ID) password.
8.2.2 Locking SP
The Locking SP controls read/write access to the media and the cryptographic erase feature. Access to the Locking SP is available
using the BandMasterX or EraseMaster passwords. Since the drive owner can define up to 16 data bands on the drive, each data band
has its own password called BandMasterX where X is the number of the data band (0 through 15).
8.2.3 Default password
When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random value can only be read by
the host electronically over the interface. After receipt of the drive, it is the responsibility of the owner to use the default MSID
password as the authority to change all other passwords to unique owner-specified values.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 44
8.3 Random number generator (RNG)
The drive has a 32-byte hardware RNG that it is uses to derive encryption keys or, if requested to do so, to provide random numbers
to the host for system use, including using these numbers as Authentication Keys (passwords) for the drive’s Admin and Locking SPs.
8.4 Drive locking
In addition to changing the passwords, as described in Section 8.2.3, the owner should also set the data access controls for the
individual bands.
The variable "LockOnReset" should be set to "PowerCycle" to ensure that the data bands will be locked if power is lost. In addition
"ReadLockEnabled" and "WriteLockEnabled" must be set to true in the locking table in order for the bands "LockOnReset" setting of
"PowerCycle" to actually lock access to the band when a "PowerCycle" event occurs. This scenario occurs if the drive is removed from
its cabinet. The drive will not honor any data read or write requests until the bands have been unlocked. This prevents the user data
from being accessed without the appropriate credentials when the drive has been removed from its cabinet and installed in another
system.
When the drive is shipped from the factory, the firmware download port is unlocked.
8.5 Data bands
When shipped from the factory, the drive is configured with a single data band called Band 0 (also known as the Global Data Band)
which comprises LBA 0 through LBA max. The host may allocate Band1 by specifying a start LBA and an LBA range. The real estate for
this band is taken from the Global Band. An additional 14 Data Bands may be defined in a similar way (Band2 through Band15) but
before these bands can be allocated LBA space, they must first be individually enabled using the EraseMaster password.
Data bands cannot overlap but they can be sequential with one band ending at LBA (x) and the next beginning at LBA (x+1).
Each data band has its own drive-generated encryption key and its own user-supplied password. The host may change the
Encryption Key (see Section 8.6) or the password when required. The bands should be aligned to 4096 native LBA boundaries.
8.6 Cryptographic erase
A significant feature of SEDs is the ability to perform a cryptographic erase. This involves the host telling the drive to change the data
encryption key for a particular band. Once changed, the data is no longer recoverable since it was written with one key and will be
read using a different key. Since the drive overwrites the old key with the new one, and keeps no history of key changes, the user
data can never be recovered. This is tantamount to an instantaneous data erase and is very useful if the drive is to be scrapped or
redispositioned.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 45
8.7 Authenticated firmware download
In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts
download files which have been cryptographically signed by the appropriate Seagate Design Center.
Three conditions must be met before the drive will allow the download operation:
1. The download must be an SED file. A standard (base) drive (non-SED) file will be rejected.
2. The download file must be signed and authenticated.
3. As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example it must be applicable to
the correct drive model, and have compatible revision and customer status.
8.8 Power consumption
The standard drive models and the SED drive models have identical hardware, however the security and encryption portion of the
drive controller ASIC is enabled and functional in the SED models. See Section 6.3 for additional information on power consumption.
8.9 Supported commands
The SED models support the following two commands in addition to the commands supported by the standard (non-SED) models as
listed in Section 8.9, "Supported commands":
• Security Protocol Out (B5h)
• Security Protocol In (A2h)
8.10 Sanitize - CRYPTOGRAPHIC ERASE
This command cryptographically erases all user data on the drive by destroying the current data encryption key and replacing it with
a new data encryption key randomly generated by the drive. Sanitize CRYPTOGRAPHIC ERASE is a SCSI CDB Op code 48h and
selecting the service action code 3 (CRYPTOGRAPHIC ERASE)
8.11 RevertSP
The SED models will support the RevertSP feature which erases all data in all bands on the device and returns the contents of all SPs
(Security Providers) on the device to their original factory state. In order to execute the RevertSP method the unique PSID (Physical
Secure ID) printed on the drive label must be provided. PSID is not electronically accessible and can only be manually read from the
drive label or scanned in via the 2D barcode.

9.0 Defect and error management
Seagate continues to use innovative technologies to manage defects and errors. These technologies are designed to increase data
integrity, perform drive self-maintenance, and validate proper drive operation.
SCSI defect and error management involves drive internal defect/error management and SAS system error considerations (errors in
communications between the initiator and the drive). In addition, Seagate provides the following technologies used to increase data
integrity and drive reliability:
• Background Media Scan (see Section 9.4)
• Deferred Auto-Reallocation (see Section 9.5)
• Idle Read After Write (see Section 9.6)
The read error rates and specified storage capacities are not dependent on host (initiator) defect management routines.
9.1 Drive internal defects/errors
During the initial drive format operation at the factory, media defects are identified, tagged as being unusable, and their locations
recorded on the drive primary defects list (referred to as the “P’ list and also as the ETF defect list). At factory format time, these
known defects are also reallocated, that is, reassigned to a new place on the medium and the location listed in the defects
reallocation table. The “P” list is not altered after factory formatting. Locations of defects found and reallocated during error recovery
procedures after drive shipment are listed in the “G” list (defects growth list). The “P” and “G” lists may be referenced by the initiator
using the Read Defect Data command.
Details of the SCSI commands supported by the drive are described in the SAS Interface Manual. Also, more information on the drive
Error Recovery philosophy is presented in the SAS Interface Manual.
9.2 Drive error recovery procedures
When an error occurs during drive operation, the drive, if programmed to do so, performs error recovery procedures to attempt to
recover the data. The error recovery procedures used depend on the options previously set in the Error Recovery Parameters mode
page. Error recovery and defect management may involve using several SCSI commands described in the SCSI Interface Manual. The
drive implements selectable error recovery time limits required in video applications.
The error recovery scheme supported by the drive provides a way to control the total error recovery time for the entire command in
addition to controlling the recovery level for a single LBA. The total amount of time spent in error recovery for a command can be
limited using the Recovery Time Limit bytes in the Error Recovery mode page. The total amount of time spent in error recovery for a
single LBA can be limited using the Read Retry Count or Write Retry Count bytes in the Error Recovery mode page.
The drive firmware error recovery algorithms consist of 20 levels for read recoveries and six levels for write. Each level may consist of
multiple steps, where a step is defined as a recovery function involving a single re-read or re-write attempt. The maximum level used
by the drive in LBA recovery is determined by the read and write retry counts.
Table 7 equates the read and write retry count with the maximum possible recovery time for read and write recovery of individual
LBAs. The times given do not include time taken to perform reallocations. Reallocations are performed when the ARRE bit (for reads)
or AWRE bit (for writes) is one, the RC bit is zero, and the recovery time limit for the command has not yet been met. Time needed to
perform reallocation is not counted against the recovery time limit.
When the RC bit is one, reallocations are disabled even if the ARRE or AWRE bits are one. The drive will still perform data recovery
actions within the limits defined by the Read Retry Count, Write Retry Count, and Recovery Time Limit parameters. However, the
drive does not report any unrecovered errors.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 47
* For read retry count, every tick ~ 5% of total error recovery. Valid range setting is 1-20.
e.g. 1 ~ 5%
5 ~ 25%
20 ~ 100%
Setting these retry counts to a value below the default setting could result in degradation of the unrecovered error rate. For example,
suppose the read/write recovery page has the RC bit = 0 and if the read retry count is set to 5, this means ~ 25% of error recovery will
be executed which consumes 621.62 ms (please refer to the table above). If the limit is reached and a LBA has not yet been recovered
(i.e. requires retries beyond 621.62 ms), the command will end with Check Condition status report and unrecoverable read error will
be reported.
9.3 SAS system errors
Information on the reporting of operational errors or faults across the interface is given in the SAS Interface Manual. The SSP
Response returns information to the host about numerous kinds of errors or faults. The Receive Diagnostic Results reports the results
of diagnostic operations performed by the drive.
Status returned by the drive to the initiator is described in the SAS Interface Manual. Status reporting plays a role in systems error
management and its use in that respect is described in sections where the various commands are discussed.

Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 48
9.4 Background Media Scan
Background Media Scan (BMS) is a self-initiated media scan. BMS is defined in the T10 document SPC-4 available from the T10
committee. BMS performs sequential reads across the entire pack of the media while the drive is idle. In RAID arrays, BMS allows hot
spare drives to be scanned for defects prior to being put into service by the host system. On regular duty drives, if the host system
makes use of the BMS Log Page, it can avoid placing data in suspect locations on the media. Unreadable and recovered error sites will
be logged or reallocated per ARRE/AWRE settings.
With BMS, the host system can consume less power and system overhead by only checking BMS status and results rather than tying
up the bus and consuming power in the process of host-initiated media scanning activity.
Since the background scan functions are only done during idle periods, BMS causes a negligible impact to system performance. The
first BMS scan for a newly manufactured drive is performed as quickly as possible to verify the media and protect data by setting the
“Start time after idle” to 5ms, all subsequent scans begin after 500ms of idle time. Other features that normally use idle time to
function will function normally because BMS functions for limited time bursts then suspends activity to allow other background
functions to operate.
BMS interrupts immediately to service host commands from the interface bus while performing reads. BMS will complete any BMS-
initiated error recovery prior to returning to service host-initiated commands. Overhead associated with a return to host-servicing
activity from BMS only impacts the first command that interrupted BMS, this results in a typical delay of about 1ms.
9.5 Deferred Auto-Reallocation
Deferred Auto-Reallocation (DAR) simplifies reallocation algorithms at the system level by allowing the drive to reallocate
unreadable locations on a subsequent write command. Sites are marked for DAR during read operations performed by the drive.
When a write command is received for an LBA marked for DAR, the auto-reallocation process is invoked and attempts to rewrite the
data to the original location. If a verification of this rewrite fails, the sector is re-mapped to a spare location.
This is in contrast to the system having to use the Reassign Command to reassign a location that was unreadable and then generate
a write command to rewrite the data. DAR is most effective when AWRE and ARRE are enabled—this is the default setting from the
Seagate factory. With AWRE and ARRE disabled DAR is unable to reallocate the failing location and will report an error sense code
indicating that a write command is being attempted to a previously failing location.
9.6 Idle Read After Write
Idle Read After Write (IRAW) utilizes idle time to verify the integrity of recently written data. During idle periods, no active system
requests, the drive reads recently written data from the media and compares it to valid write command data resident in the drives
data buffer. Any sectors that fail the comparison result in the invocation of a rewrite and auto-reallocation process. The process
attempts to rewrite the data to the original location. If a verification of this rewrite fails, the sector is re-mapped to a spare location.
9.7 Protection Information (PI)
Protection Information is intended as a standardized approach to system level LRC traditionally provided by systems using 520 byte
formatted LBAs. Drives formatted with PI information provide the same, common LBA count (i.e. same capacity point) as non-PI
formatted drives. Sequential performance of a PI drive will be reduced by approximately 1.56% due to the extra overhead of PI being
transferred from the media that is not calculated as part of the data transferred to the host. To determine the full transfer rate of a PI
drive, transfers should be calculated by adding the 8 extra bytes of PI to the transferred LBA length, i.e. 512 + 8 = 520. PI formatted
drives are physically formatted to 520 byte sectors that store 512 bytes of customer data with 8 bytes of Protection Information
appended to it. The advantage of PI is that the Protection Information bits can be managed at the HBA and HBA driver level. Allowing
a system that typically does not support 520 LBA formats to integrate this level of protection.
Protection Information is valid with any supported LBA size. 512 LBA size is used here as common example.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 49
9.7.1 Levels of PI
There are 4 types of Protection Information.
Type 0 - Describes a drive that is not formatted with PI information bytes. This allows for legacy support in non-PI systems.
Type 1 - Provides support of PI protection using 10 and 16 byte commands. The RDPROTECT and WRTPROTECT bits allow for
checking control through the CDB. Eight bytes of Protection Information are transmitted at LBA boundaries across the interface if
RDPROTECT and WRTPROTECT bits are nonzero values. Type 1 does not allow the use of 32 byte commands.
Type 2 - Provides checking control and additional expected fields within the 32 byte CDBs. Eight bytes of Protection Information are
transmitted at LBA boundaries across the interface if RDPROTECT and WRTPROTECT bits are nonzero values. Type 2 does allow the
use of 10 and 16 byte commands with zero values in the RDPROTECT and WRTPROTECT fields. The drive will generate 8 bytes
(e.g.0xFFFF) 8 bytes of Protection Information to be stored on the media, but the 8 bytes will not be transferred to the host during a
read command.
Type 3 - Seagate products do not support Type 3.
9.7.2 Setting and determining the current Type Level
A drive is initialized to a type of PI by using the format command on a PI capable drive. Once a drive is formatted to a PI Type, it may
be queried by a Read Capacity (16) command to report the PI type which it is currently formatted to. PI Types cannot coexist on a
single drive. A drive can only be formatted to a single PI Type. It can be changed at anytime to a new Type but requires a low level
format which destroys all existing data on the drive. No other vehicle for changing the PI type is provided by the T10 SBC3
specification.
Type 1 PI format CDB command: 04 90 00 00 00 00, Write Buffer: 00 A0 00 00
Type 2 PI format CDB command: 04 D0 00 00 00 00, Write Buffer: 00 A0 00 00
9.7.3 Identifying a Protection Information drive
The Standard Inquiry provides a bit to indicate if PI is support by the drive. Vital Product Descriptor (VPD) page 0x86 provides bits to
indicate the PI Types supported and which PI fields the drive supports checking.
9.8 Seagate RAID Rebuild ™
Seagate RAID Rebuild is an industry standard feature to enable faster recovery from a failed drive in a RAID configuration. It improves
RAID rebuild performance by extracting easily readable data from a failing drive. It quickly identifies blocks that would take longer to
recover from the failed drive than to rebuild from the remaining drives in the RAID group.
This feature allows host control of error recovery, maximizes up time, and minimizes likelihood of 2nd drive failure in a RAID
configuration.
NOTE For further details with respect to PI, please refer to SCSI Block
Commands - 3 (SBC-3) Draft Standard documentation.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 50
10.0 Installation
Seagate Enterprise Performance 10K HDD disk drive installation is a plug-and-play process. There are no jumpers, switches, or
terminators on the drive.
SAS drives are designed to be used in a host system that provides a SAS-compatible backplane with bays designed to accommodate
the drive. In such systems, the host system typically provides a carrier or tray onto which the drive needs to be mounted. Mount the
drive to the carrier or tray provided by the host system using four M3 x 0.5 metric screws. When tightening the screws, use a
maximum torque of 4.5 in-lb +/- 0.45 in-lb. Do not over-tighten or force the screws. Mount the drive in any orientation.
Slide the carrier or tray into the appropriate bay in the host system using the instructions provided by the host system. This connects
the drive directly to the system’s SAS connector. The SAS connector is normally located on a SAS backpanel. See Section 11.4.1 for
additional information about these connectors.
Power is supplied through the SAS connector.
The drive is shipped from the factory low-level formatted in 512-byte logical blocks for 512 emulation and native drives and 4096-byte
logical blocks for 4096 native drives. Reformat the drive only if a different logical block size needs to be selected.
Figure 12. Physical interface
10.1 Drive orientation
The drive may be mounted in any orientation. All drive performance characterizations, however, have been done with the drive in
horizontal (discs level) and vertical (drive on its side) orientations, which are the two preferred mounting orientations.
10.2 Cooling
Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding the drive does not
result in the drive exceeding temperature conditions specified in Section 6.5.1, "Temperature".
The rack, cabinet, or drawer environment for the drive must provide heat removal from the electronics and head and disk assembly
(HDA). Confirm that adequate heat removal is provided using the temperature measurement guidelines described in Section 6.5.1.
Forced air flow may be required to keep temperatures at or below the temperatures specified in Section 6.5.1 in which case the drive
should be oriented, or air flow directed, so that the least amount of air flow resistance is created while providing air flow to the
electronics and HDA. Also, the shortest possible path between the air inlet and exit should be chosen to minimize the travel length of
air heated by the drive and other heat sources within the rack, cabinet, or drawer environment.
NOTE
SAS drives are designed to be attached to the host system without I/O or power cables. If the
intent is to use the drive in a non-backplane host system, connecting the drive using high-quality
cables is acceptable as long as the I/O cable length does not exceed 10 meters (32.8 feet).
NOTE Image is for reference only, may not represent actual drive.
Seagate Enterprise Performance 10K HDD v8 w/TurboBoost Product Manual, Rev. D 51
If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 13. The air-flow patterns are created by one
or more fans, either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced air-flow patterns are
acceptable as long as the temperature measurement guidelines of Section 6.5.1 are met.
Figure 13. Air flow
10.3 Drive mounting
Mount the drive using the bottom or side mounting holes. If mounting the drive using the bottom holes, ensure to not physically
distort the drive by attempting to mount it on a stiff, non-flat surface.
The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm). The following equation and paragraph define the allowable
mounting surface stiffness:
where K is the mounting surface stiffness (units in lb/in or N/mm) and X is the out-of-plane surface distortion (units in inches or
millimeters). The out-of-plane distortion (X) is determined by defining a plane with three of the four mounting points fixed and
evaluating the out-of-plane deflection of the fourth mounting point when a known force (F) is applied to the fourth point.
10.4 Grounding
Signal ground (PCBA) and HDA ground are connected together in the drive and cannot be separated by the user. The equipment in
which the drive is mounted is connected directly to the HDA and PCBA with no electrically isolating shock mounts. If it is desired for
the system chassis to not be connected to the HDA/PCBA ground, the systems integrator or user must provide a nonconductive
(electrically isolating) method of mounting the drive in the host equipment.
Increased radiated emissions may result if maximum surface area ground connection is not provided between system ground and
drive ground. This is the system designer’s and integrator’s responsibility.
NOTE Image of the HDA may not represent actual product, for reference only.

11.3.2 Mode Sense data
The Mode Sense command provides a way for the drive to report its operating parameters to the initiator. The drive maintains four
sets of mode parameters:
1. Default values
Default values are hard-coded in the drive firmware stored in flash E-PROM (nonvolatile memory) on the drive’s PCB. These
default values can be changed only by downloading a complete set of new firmware into the flash E-PROM. An initiator can
request and receive from the drive a list of default values and use those in a Mode Select command to set up new current and
saved values, where the values are changeable.
2. Saved values
Saved values are stored on the drive’s media using a Mode Select command. Only parameter values that are allowed to be
changed can be changed by this method. Parameters in the saved values list that are not changeable by the Mode Select com-
mand get their values from default values storage.
When power is applied to the drive, it takes saved values from the media and stores them as current values in volatile memory. It
is not possible to change the current values (or the saved values) with a Mode Select command before the drive achieves operat-
ing speed and is “ready.” An attempt to do so results in a “Check Condition” status.
On drives requiring unique saved values, the required unique saved values are stored into the saved values storage location on
the media prior to shipping the drive. Some drives may have unique firmware with unique default values also.
On standard OEM drives, the saved values are taken from the default values list and stored into the saved values storage location
on the media prior to shipping.
3. Current values
Current values are volatile values being used by the drive to control its operation. A Mode Select command can be used to
change the values identified as changeable values. Originally, current values are installed from saved or default values after a
power on reset, hard reset, or Bus Device Reset message.
4. Changeable values
Changeable values form a bit mask, stored in nonvolatile memory, that dictates which of the current values and saved values can
be changed by a Mode Select command. A one (1) indicates the value can be changed. A zero (0) indicates the value is not
changeable. For example, in the table in Section 11.3.2, refer to Mode page 81, in the row entitled “CHG.” These are hex numbers
representing the changeable values for Mode page 81. Note in columns 5 and 6 (bytes 04 and 05), there is 00h which indicates
that in bytes 04 and 05 none of the bits are changeable. Note also that bytes 06, 07, 09, 10, and 11 are not changeable, because
those fields are all zeros. In byte 02, hex value FF equates to the binary pattern 11111111. If there is a zero in any bit position in
the field, it means that bit is not changeable. Since all of the bits in byte 02 are ones, all of these bits are changeable.
The changeable values list can only be changed by downloading new firmware into the flash E-PROM.
The following tables list the values of the data bytes returned by the drive in response to the Mode Sense command pages for SCSI
implementation (see the SAS Interface Manual ).
DEF = Default value. Standard OEM drives are shipped configured this way.
CHG = Changeable bits; indicates if default value is changeable.
NOTE Because there are often several different versions of drive control firmware in the total population of drives in
the field, the Mode Sense values given in the following tables may not exactly match those of some drives.

future revision of this publication when production parts are available from major connector manufacturers.
The SAS device connector is illustrated in Figures 15 and 16.
11.4.4 Electrical description
SAS drives use the device connector for:
•DC power
•SAS interface
•Activity LED
This connector is designed to either plug directly into a backpanel or accept cables.
11.4.5 Pin descriptions
This section provides a pin-out of the SAS device and a description of the functions provided by the pins.
Table 19 SAS pin descriptions
* - Short pin to support hot plugging
** - Power Disable (T10 Industry Standard) for remote management of the end device.
Allows power cycling / power saving to be controlled by the host via interface pin 3.
Pin P3 of the power connector on the interface may be pulled high, above 1.8V, to shut off power to the drive.
Pulling pin p3 low, below 0.7V (but not negative), allows the drive to run.
NC - No connection in the drive.

11.4.6 SAS transmitters and receivers
A typical SAS differential copper transmitter and receiver pair is shown in Figure 17. The receiver is AC coupling to eliminate ground
shift noise.
Figure 17. SAS transmitters and receivers
11.4.7 Power
The drive receives power (+5 volts and +12 volts) through the SAS device connector.
Three +12 volt pins provide power to the drive, 2 short and 1 long. The current return for the +12 volt power supply is through the
common ground pins. The supply current and return current must be distributed as evenly as possible among the pins.
Three +5 volt pins provide power to the drive, 2 short and 1 long. The current return for the +5 volt power supply is through the
common ground pins. The supply current and return current must be distributed as evenly as possible among the pins.
Current to the drive through the long power pins may be limited by the system to reduce inrush current to the drive during hot
plugging.
11.5 Signal characteristics
This section describes the electrical signal characteristics of the drive’s input and output signals. See Section 11.4.5 for signal type
and signal name information.
11.5.1 Ready LED Out
The Ready LED Out signal is driven by the drive as indicated in the table below.

The Ready LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +3.3 volt supply
through an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive. See the next table
for the output characteristics of the LED drive signals.
11.5.2 Differential signals
The drive SAS differential signals comply with the intra-enclosure (internal connector) requirements of the SAS standard.
The table below defines the general interface characteristics
11.6 SAS-3 Specification compliance
Seagate SAS-3 compatible drives are compliant with the latest SAS-3 Specification (T10/BSR INCITS 519 rev. 06).
The main difference from SAS-2 is the Tx and Rx training that allows the host and drive to adjust the amplitude and emphasis values
to the channel. The receiver still employs Decision Feedback Equalizer (DFE) and Feed Forward Equalizer (FFE) circuitry to accomplish
this training.
11.7 Additional information
Please contact the Seagate representative for SAS electrical details, if required.
