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

1.1 About the SATA interface
The Serial ATA (SATA) 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, SA TA makes the transition from parallel ATA easy by providing legacy software support. SATA was designed to allow users
to install a SATA host adapter and SATA disk drive in the current system and expect all of the existing applications to work as normal.
The SATA interface connects each disk drive in a point-to-point configuration with the SATA host adapter. There is no master/slave
relationship with SATA devices like there is with parallel ATA. If two drives are attached on one SATA 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 SATA 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 SATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the
Shadow Register Block. All SATA devices behave like Device 0 devices. For additional information about how SATA emulates parallel
A TA, refer to the “Serial ATA International Organization: Serial ATA Revision 3.0”. The specification can be downloaded from www.sata-
io.org.
The host adapter may, optionally, emulate a master/slave environment to host software where two
Note
devices on separate SA TA 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 SATA environment.

2.6 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.
Typical seek times (ms) Read Write
Track-to-track 1.0 1.2
Average 8.5 9.5
Average latency 4.0
These drives are designed to consistently meet the seek times represented in this manual. Physical seeks,
Note
regardless of mode (such as track-to-track and average), are expected to meet the noted 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 Start/stop times

2.8 Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to Figure 1 on page 16.
2.8.1 Power consumption
Power requirements for the drives are listed in Table 2. Typical power measurements are based on an average of drives tested, under
nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature.
• Spinup power
Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.
• Read/write power and current
Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-ms delay , then a 16-sector read
followed by a 32-ms delay.
• Operating power and current
Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each 10 reads) and 20 percent drive idle mode.
• 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.

2.8.2 Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt line or an
equivalent 15-ohm resistive load on the +5 volt line.
• Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected noise at up to
10MHz.
• Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave injected noise at up to
10MHz.
Note
Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

2.8.4 Power-management modes
The drive provides programmable power management to provide greater energy efficiency. In most systems, users can control power
management through the system setup program. The drive features the following power-management modes:
Power modes Heads Spindle Buffer
Active Tracking Rotating Enabled
Idle Tracking Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled
• 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.

2.10.1 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.

2.14 Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting certain
chemical substances.
2.14.1 European Union Restriction of Hazardous Substances (RoHS) Directive
The European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemical substances, including
Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE, in electronic products, effective July 2006. This drive is
manufactured with components and materials that comply with the RoHS Directive.
2.14.2 China Restriction of Hazardous Substances (RoHS) Directive
This product has an Environmental Protection Use Period (EPUP) of 20 years. The following table contains information
mandated by China's "Marking Requirements for Control of Pollution Caused by Electronic Information Products"
Standard.
"O" indicates the hazardous and toxic subst ance content of the part (at th e homogeneous material level) is lower than the threshold
defined by the China RoHS MCV Standard.
"X" indicates the hazardous and toxic substance content of the part (at the homogeneous material level) is over the threshold defined
by the China RoHS MCV Standard.
2.15 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 sulfidefree alternatives.

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:
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.
3.2 Configuring the drive
Each drive on the SATA interface connects point-to-point with the SATA 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 SATA 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.
SA TA drives are designed for easy installation. It is usually not necessary to set any jumpers on the drive for proper operation; however,
if users connect the drive and receive a “drive not detected” error, the SATA-equipped motherboard or host adapter may use a chipset
that does not support SATA speed autonegotiation.
3.3 SATA cables and connectors
The SATA 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 inches). See
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 1 Attaching SATA cabling
Signal connector
Power connector
Signal cable
Power cable
Each cable is keyed to ensure correct orientation. Enterprise NAS HDD v2 drives support latching SATA connectors.
Table 7 for connector pin definitions. Either end of the SATA
Figure 1.
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.
Refer to
• Allow a minimum clearance of 0.030 inches (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 0.150 inch (3.81mm) into the bottom or side mounting holes.
• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

4.3.2 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:

4.3.3 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
returns. The diagnostic software ships with all new drives and is also available at:
http://seatools.seagate.com.
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.
