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.

addressing support of drives with capacities over 137GB.

2.3 Recording and interface technology

2.4 Start/stop times

Power-on to ready time is based on typical operating conditions, default full current spin-up profile, and clean

shutdown prior to measurement. To ensure a clean shutdown a Flush Cache, Standby, or Standby Immediate

command must be completed before removal of interface power.

NOTE An unexpected power loss event, spin up at cold or hot temperature extremes may

cause the drive to exceed the typical and max time to ready by 5 to 20 seconds.

Extended time to ready is dependent on cache state and environmental conditions

prior to the unexpected power loss and during the subsequent power on.

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.

+5v = 250 mV pp from 100 Hz to 20 MHz.

+12v = 800 mV pp from 100 Hz to 8 KHz.

450 mV pp from 8 KHz to 20 KHz.

250 mV pp from 20 KHz to 5 MHz.

Power Condition Name Power Condition ID Description

Idle_a 81HReduced electronics

Idle_b 82HHeads unloaded. Disks spinning at full RPM

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).

2.6.1 Temperature

a. Operating

32°F to 149°F (0°C ambient to 65°C drive reported) temperature range with a maximum temperature gradient of 36°F

(20°C) per hour.

The maximum allowable drive reported temperature is 149°F (65°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.

Seagate IronWolf Pro SATA +Rescue Product Manual, Rev. A 16

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 0.73% (MTBF of 1,200,000 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 (command controlled) 600,000 cycles

Maximum Rated Workload Maximum rate of <300TB/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 HDD and SSD Regulatory Compliance and Safety

For the latest regulatory and compliance information see: www.seagate.com/support scroll down

the page and click the Compliance, Safety and Disposal Guide link.

2.11.1 Regulatory Models

The following regulatory model number represent all features and configurations within the series:

Regulatory Model Numbers: STL020

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.

www.seagate.com Configuring and mounting the drive

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 5 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 3.

Figure 3. Attaching SATA cabling

Each cable is keyed to ensure correct orientation. IronWolf Pro SATA +Rescue 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.

www.seagate.com Configuring and mounting the drive

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 4 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 4 for detailed mounting configuration dimensions. See Section 3.4, “Drive mounting.”

4.3.4 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.

02HEnable write cache (default).

03HSet transfer mode (based on value in Sector Count register).

4.3.5 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.
