www.seagate.com Introduction
1.1 About the Serial ATA interface
The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary
advantages include:
Easy installation and configuration with true plug-and-play connectivity.
It is not necessary to set any jumpers or other configuration options.
Thinner and more flexible cabling for improved enclosure airflow and ease of installation.
Scalability to higher performance levels.
In addition, Serial ATA makes the transition from parallel ATA easy by providing legacy software support. Serial ATA
was designed to allow users to install a Serial ATA host adapter and Serial ATA disk drive in the current system and
expect all of the existing applications to work as normal.
The Serial ATA interface connects each disk drive in a point-to-point configuration with the Serial ATA host adapter.
There is no master/slave relationship with Serial ATA devices like there is with parallel ATA. If two drives are attached
on one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters” on two
separate ports. This essentially means both drives behave as if they are Device 0 (master) devices.
NOTE The host adapter may, optionally, emulate a master/slave environment to host software
where two devices on separate Serial ATA ports are represented to host software as a
Device 0 (master) and Device 1 (slave) accessed at the same set of host bus addresses. A
host adapter that emulates a master/slave environment manages two sets of shadow
registers. This is not a typical Serial ATA environment.
The Serial ATA host adapter and drive share the function of emulating parallel ATA device behavior to provide
backward compatibility with existing host systems and software. The Command and Control Block registers, PIO and
DMA data transfers, resets, and interrupts are all emulated.
The Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device registers,
referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For additional
information about how Serial ATA emulates parallel ATA, refer to the “Serial ATA: High Speed Serialized AT Attachment”
specification. The specification can be downloaded from www.serialata.org.

2.5.4 Extended Power Conditions - PowerChoice™
Utilizing the load/unload architecture a programmable power management interface is provided to tailor systems for
reduced power consumption and performance requirements.
The table below lists the supported power conditions available in PowerChoice. Power conditions are ordered from
highest power consumption (and shortest recovery time) to lowest power consumption (and longest recovery time)
as follows: Idle_a power >= Idle_b power >= Idle_c power >= Standby_z power. The further users go down in the
table, the more power savings is actualized. For example, Idle_b results in greater power savings than the Idle_a
power condition. Standby results in the greatest power savings.
Each power condition has a set of current, saved and default settings. Default settings are not modifiable. Default and
saved settings persist across power-on resets. The current settings do not persist across power-on resets. At the time
of manufacture, the default, saved and current settings are in the Power Conditions log match.
PowerChoice is invoked using one of two methods
Automatic power transitions which are triggered by expiration of individual power condition timers. These timer
values may be customized and enabled using the Extended Power Conditions (EPC) feature set using the
standardized Set Features command interface.
Immediate host commanded power transitions may be initiated using an EPC Set Features "Go to Power
Condition" subcommand to enter any supported power condition. Legacy power commands Standby Immediate
and Idle Immediate also provide a method to directly transition the drive into supported power conditions.
PowerChoice exits power saving states under the following conditions

2.6 Environmental limits
Temperature and humidity values experienced by the drive must be such that condensation does not occur on any
drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C).
NOTE To maintain optimal performance drives should be run at nominal drive
temperatures and humidity.
See Section 2.10, "Reliability" for rated MTBF device operating condition
requirements.
2.6.1 Temperature
a. Operating
41°F to 140°F (5°C to 60°C) temperature range with a maximum temperature gradient of 36°F (20°C) per hour as reported by the
drive.
The maximum allowable drive reported temperature is 140°F (60°C).
Air flow may be required to achieve consistent nominal drive temperature values (see Section 3.4). To confirm that the
required cooling is provided for the electronics and HDA, place the drive in its final mechanical configuration, and perform
random write/read operations. After the temperatures stabilize, monitor the current drive temperature using the SMART
temperature attribute 194 or Device Statistics log 04h page 5.
b. Non-operating
–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification assumes that
the drive is packaged in the shipping container designed by Seagate for use with drive.
2.6.2 Humidity

noise specified below.
Seagate Exos X18 SATA Product Manual, Rev. C 21
www.seagate.com Drive specifications
2.7 Acoustics
Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements
are consistent with ISO document 7779. Sound power measurements are taken under essentially free-field conditions
over a reflecting plane. For all tests, the drive is oriented with the cover facing upward.
NOTE For seek mode tests, the drive is placed in seek mode only. The number of seeks
per second is defined by the following equation:
(Number of seeks per second = 0.4 / (average latency + average access time
)
*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which
may increase acoustic and power to operational levels.
2.8 Test for Prominent Discrete Tones (PDTs)
Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this process is
the use of the absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 389-7) to discern
tone audibility and to compensate for the inaudible components of sound prior to computation of tone ratios
according to Annex D of the ECMA-74 standards.
2.9 Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in
performance when subjected to the radio frequency (RF) environments defined in the following table:

2.10 Reliability
2.10.1 Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)
The production disk drive shall achieve an annualized failure-rate of 0.35% (MTBF of 2,500,000 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 <= 30°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.
Nonrecoverable read errors 1 per 1015 bits read, max
Load unload cycles 600,000 cycles
Maximum Rated Workload Maximum rate of <550TB/year
Workloads exceeding the annualized rate may degrade the drive MTBF and impact product
reliability. The Annualized Workload Rate is in units of TB per year, or TB per 8760 power on hours.
Workload Rate = TB transferred * (8760 / recorded power on hours).

2.11.1 Regulatory Models
The following regulatory model number represent all features and configurations within the series:
Regulatory Model Numbers: STL014
2.12 Corrosive environment
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.

Seagate warrants that each product (including components and subassemblies) that fails to function properly under
normal use due to defect in materials or workmanship or due to nonconformance to the applicable specifications will
be repaired or replaced, at Seagate’s option and at no charge to the customer, if returned by customer at customer’s
expense to Seagate’s designated facility in accordance with Seagate’s warranty procedure. Seagate will pay for
transporting the repair or replacement item to the customer. For more detailed warranty information, refer to the
standard terms and conditions of purchase for Seagate products on the purchase documentation.
The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at 1-800-468-
3472. Users can also determine remaining warranty using the Seagate web site (www.seagate.com). The drive serial
number is required to determine remaining warranty 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 the authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping by an air-
ride carrier experienced in handling computer equipment.
Storage
Maximum storage periods are 180 days within original unopened Seagate shipping package or 60 days unpackaged
within the defined non-operating limits (refer to environmental section in this manual). Storage can be extended to 1
year packaged or unpackaged under optimal environmental conditions (25°C, <40% relative humidity non-
condensing, and non-corrosive environment). 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.

3.0 Configuring and mounting the drive
This section contains the specifications and instructions for configuring and mounting the drive.
3.1 Handling and static-discharge precautions
After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge
(ESD) hazards. Observe the following standard handling and static-discharge precautions:
3.2 Configuring the drive
Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no master/
slave relationship because each drive is considered a master in a point-to-point relationship. If two drives are attached
on one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters” on two
separate ports. Both drives behave as if they are Device 0 (master) devices.
3.3 Serial ATA cables and connectors
The Serial ATA interface cable consists of four conductors in two differential pairs, plus three
ground connections. The cable size may be 30 to 26 AWG with a maximum length of one
meter (39.37 in).
See Table 12 for connector pin definitions. Either end of the SATA signal cable can be
attached to the drive or host.
For direct backplane connection, the drive connectors are inserted directly into the host
receptacle. The drive and the host receptacle incorporate features that enable the direct
connection to be hot pluggable and blind mateable.
For installations which require cables, users can connect the drive as illustrated in Figure 2.
Figure 2. Attaching SATA cabling
Each cable is keyed to ensure correct orientation. Exos X18 SATA drives support latching SATA connectors.
Caution
• Before handling the drive, put on a grounded wrist strap, or ground oneself frequently by touching the metal chassis of a
computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire installation procedure.
• Handle the drive by its edges or frame only.
• The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until mounting it in the computer.
• Do not touch the connector pins or the printed circuit board.
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty.
Some factory-installed labels contain information needed to service the drive. Other labels are used to seal out dirt and
contamination.

3.4 Drive mounting
Users can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the
bottom-mounting holes. See Figure 3 for drive mounting dimensions. Follow these important mounting precautions
when mounting the drive:
Allow a minimum clearance of 0.030 in (0.76mm) around the entire perimeter of the drive for cooling.
Use only 6-32 UNC mounting screws.
The screws should be inserted no more than 0.140 in (3.56mm) into the bottom or side mounting holes.
Do not overtighten the mounting screws (maximum torque: 6 in-lb).
3.4.1 Mechanical specifications
Refer to Figure 3 for detailed mounting configuration dimensions. See Section 3.4, “Drive mounting.”

www.seagate.com About self-encrypting drives
4.0 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 2.13.
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 ATA
commands:
Trusted Send
Trusted Receive
These commands are used to convey the TCG protocol to and from the drive in their command payloads.
4.1 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 4.5).
4.2 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.
4.2.1 Admin SP
The Admin SP allows the drive's owner to enable or disable firmware download operations (see Section 4.4). Access
to the Admin SP is available using the SID (Secure ID) password or the MSID (Manufacturers Secure ID) password.
4.2.2 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).
4.2.3 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 Exos X18 SATA Product Manual, Rev. C 28
www.seagate.com About self-encrypting drives
4.3 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.
4.4 Drive locking
In addition to changing the passwords, as described in Section 4.2.3, 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.
4.5 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 30 Data Bands may be
defined in a similar way (Band2 through Band31) 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 4.6) or the password when required. The bands should be aligned to 4K LBA
boundaries.
4.6 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.
4.7 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.
Seagate Exos X18 SATA Product Manual, Rev. C 29
www.seagate.com About self-encrypting drives
4.8 Power requirements
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. This represents a small additional
drain on the 5V supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is
no additional drain on the 12V supply. See the tables in Section 2.5 for power requirements on the standard (non-
SED) drive models.
4.9 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 Table 13:
Trusted Send (5Eh) or Trusted Send DMA (5Fh)
Trusted Receive (5Ch) or Trusted Receive DMA (5D)
4.10 RevertSP
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.
4.11 ATA Security Erase Unit Command on SED SATA drives
The ATA SECURITY ERASE UNIT command shall support both the Normal and Enhanced erase modes with the
following modifications/additions:
Normal Erase: Normal erase shall be accomplished by changing the media encryption key for the drive followed
by an overwrite operation that repeatedly writes a single sector containing random data to the entire drive. The
write operation shall bypass the media encryption. On reading back the overwritten sectors, the host will receive
a decrypted version, using the new encryption key, of the random data sector (the returned data will not match
what was written).
Enhanced Erase: Enhanced erase shall be accomplished by changing the media encryption key for the drive.
4.12 Sanitize Device - CRYPTO SCRAMBLE EXT
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 Device is a command field B4h
and Feature field 0011h (CRYPTO SCRAMBLE EXT).
The drive shall support the Sanitize Feature Set as defined in ANSI/INCITS ACS-2 with the exceptions and/or
modifications described in this section.
Support of the SANITIZE FREEZE LOCK EXT command shall be determined on a customer-specific basis. OEM drives
shall support the command.

5.3.4 Set Features command
This command controls the implementation of various features that the drive supports. When the drive receives this
command, it sets BSY, checks the contents of the Features register, clears BSY and generates an interrupt. If the value
in the register does not represent a feature that the drive supports, the command is aborted. Power-on default has the
read look-ahead and write caching features enabled. The acceptable values for the Features register are defined as
follows:
NOTE At power-on, or after a hardware or software reset, the default values of the
features are as indicated above.

5.3.5 S.M.A.R.T. commands
S.M.A.R.T. provides near-term failure prediction for disk drives. When S.M.A.R.T. is enabled, the drive monitors
predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines that a
failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable. S.M.A.R.T.
predictability is limited to the attributes the drive can monitor. For more information on S.M.A.R.T. commands and
implementation, see the Draft ATA-5 Standard.
SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4H) that eliminates
unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:
www.seagate.com/support/downloads/seatools/.
This drive is shipped with S.M.A.R.T. features disabled. Users must have a recent BIOS or software package that
supports S.M.A.R.T. to enable this feature. The table below shows the S.M.A.R.T. command codes that the drive uses.
NOTE If an appropriate code is not written to the Features Register, the command is
aborted and 0x 04 (abort) is written to the Error register.
