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.

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

The MTBF specification for the drive assumes the I/O workload does not exceed the average annualized workload rate limit of 55TB/year. Workloads exceeding the annualized rate
may degrade the drive MTBF and impact product reliability. The average annualized workload rate limit is in units of TB per year, or TB per 8760 power-on hours. Workload rate limit
= TB transferred × (8760/recorded power-on hours).

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.

Note
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 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.

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

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.

Reliability
2.11.1 Annualized Failure Rate (AFR)
The product will achieve an Annualized Failure Rate (AFR) of 0.55% when operated in an environment of ambient air
temperatures of 25°C. Operation at temperatures outside the specifications in Section 2.8, Environmental Specifications may
increase the product AFR. AFR is a population statistics that is not relevant to individual units.
AFR specifications are based on the following assumptions for consumer electronics environments:
• 8760 power-on-hours per year
• 10,000 average motor start/stop cycles per year
• Operations at nominal voltages
• Temperatures outside the specifications in Section 2.8, Environmental Specifications may reduce the product reliability.
• Normal I/O duty cycle for consumer electronics environments. Operation at excessive I/O duty cycle may degrade
product reliability.
The consumer electronics environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR. The AFR
will be degraded if used in a enterprise application

Environmental Protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting certain chemical
substances.
2.13.1
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.
2.13.2
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 substance content of the part (at the homogenous 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 homogenous material level) is over the threshold defined by the
China RoHS MCV Standard.
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.

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
3.2
• 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.
• 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.
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.
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.

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:
Table 12 Set Features command values
02H
Enable write cache (default).
03H
Set transfer mode (based on value in Sector Count register).
Sector Count register values:
00H Set PIO mode to default (PIO mode 2).
01H Set PIO mode to default and disable IORDY (PIO mode 2).
08H PIO mode 0

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: 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.
