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

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 you to install a Serial ATA host adapter and Serial ATA disk drive in your current system and expect all of your 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.

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

NOTE

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.

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 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 International Organization: Serial ATA (Revision 2.6). The specification can be downloaded from

www.serialata.org.

2.5 SEEK TIME

Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The
specifications in the table below are defined as follows:

 Track-to-track seek time is an average of all possible single-track seeks in both directions.
 Average seek time is a true statistical random average of at least 5000 measurements of seeks between random tracks, less overhead.

Table 2 Typical seek times

Typical seek times (ms) Read

Track-to-track 1.5
Average 12.0
Average latency 5.6

These drives are designed to consistently meet the seek times represented in this manual. Physical
seeks, regardless of mode (such as track-to-track and average), are expected to meet the noted

NOTE

values. However, due to the manner in which these drives are formatted, benchmark tests that
include command overhead or measure logical seeks may produce results that vary from these
specifications.

2.7 POWER SPECIFICATIONS

The drive receives DC power (+5V) through a native SATA power connector (refer to Figure 2).

2.7.1 Power consumption

Power requirements for the drives are listed in the table in
tested, under nominal conditions, at 25°C ambient temperature. These power measurements are done with Interface Power
Management modes like HIPM and DIPM enabled.

 Spinup power

Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.

 Seek mode

During seek mode, the read/write actuator arm moves toward a specific position on the disk surface and does not execute a read or
write operation. Servo electronics are active. Seek mode power is measured based on three random seek operations every 100 ms. This
mode is not typical.

 Read/write power and current

Read/write power is measured with the heads on track, based on three 63 sector read or write operations every 100 ms.

Table 4. Typical power measurements are based on an average of drives

 Idle mode power

Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track location.

 Standby mode

During standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/write electronics are in
power-down mode.

 Active mode

The drive is in active mode during the read/write and seek operations.

 Idle mode

The buffer remains enabled, and the drive accepts all commands and returns to active mode any time disk access is necessary.

 Standby mode

The drive enters standby mode when the host sends a standby Immediate command. If the host has set the standby timer, the drive can
also enter standby mode automatically after the drive has been inactive for a specifiable length of time. The standby timer delay is
established using a standby or idle command. In standby mode, the drive buffer is enabled, the heads are parked and the spindle is at
rest. The drive accepts all commands and returns to active mode any time disk access is necessary.

 Sleep mode

The drive enters sleep mode after receiving a sleep command from the host. In sleep mode, the drive buffer is disabled, the heads are
parked and the spindle is at rest. The drive leaves sleep mode after it receives a hard reset or soft reset from the host. After receiving a
reset, the drive exits sleep mode and enters standby mode with all current translation parameters intact.

 Idle and standby timers

Each time the drive performs an active function (read, write or seek), the standby timer is reinitialized and begins counting down from
its specified delay times to zero. If the standby timer reaches zero before any drive activity is required, the drive makes a transition to
standby mode. In both Idle and standby mode, the drive accepts all commands and returns to active mode when disk access is
necessary.

2.14 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 Seagate
products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging.
In addition, electronic components should never be exposed to condensing water on the surface of the printed circuit board assembly
(PCBA) or exposed to an ambient relative humidity greater than 95%. 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.

MOMENTUS THIN SATA PRODUCT MANUAL, REV. G 14

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.

• Keep the drive in the electrostatic discharge (ESD) bag until you are ready for installation to limit the
drive’s exposure to ESD.

• Before handling the drive, put on a grounded wrist strap, or ground yourself 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.

CAUTION

3.2 CONFIGURING THE DRIVE

Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host adapter. There is no master/
slave relationship because each drive is considered a master in a point-to-point relationships. 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.

• 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 you mount 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.

3.2.1 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). Refer to Table 8 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, you
can connect the drive as shown in Figure 2.

MOMENTUS THIN SATA PRODUCT MANUAL, REV. G 15

CONFIGURING AND MOUNTING THE DRIVE

3.3 DRIVE MOUNTING

You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-mounting holes.
Refer to Figure 3 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive:

 Allow a minimum clearance of 0.030 in (0.76 mm) around the entire perimeter of the drive for cooling.
 Use only M3 x 0.5 mounting screws.
 Do not overtighten the mounting screws. Maximum torque: 4.0 in-lb (0.4519 N-m).
 Four (4) threads (0.080 in, 2.032 mm) minimum screw engagement recommended.
 Avoid excessive drive distortion when mounting. Refer to the following specifications for stiffness/deflection information:

Top cover stiffness/deflection

Operating: no performance degradation, emitted noise,
mechanical damage, or hard errors

10 mm probe: 1.02kgf or
5 mm probe: 0.92kgf

ABOUT FIPS

4.0 ABOUT FIPS

The Federal Information Processing Standard (FIPS) Publication 140-2, FIPS PUB 140-2, is a U.S. government computer security
standard used to accredit cryptographic modules. It is titled “Security Requirements for Cryptographic Modules”. The initial publication
was on May 25, 2001 and was last updated December 3, 2002.

Purpose.

The National Institute of Standards and Technology (NIST) issued the FIPS 140 Publication Series to coordinate the requirements and
standards for cryptography modules that include both hardware and software components.

Federal Information Processing Standard (FIPS) 140-2 Level 2 Certification requires drives to go through government agencies
certifications to add requirements for physical tamper-evidence and role-based authentication. 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 requirement for
tamper-evidence, which includes the use of tamper-evident coatings or seals on removable covers of the module. Tamper-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 5, page 19) 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 perform a corresponding set of
services.

5.3.2 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:

5.3.3 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 D4

) that eliminates unnecessary drive

H

returns. The diagnostic software ships with all new drives and is also available at:

http://www.seagate.com/support/downloads/seatools/.

This drive is shipped with S.M.A.R.T. features disabled. You 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.
