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. Department of Commerce, Bureau of Industry and Security (for

These drives provide the following key features:
• 7200 RPM spindle speed.
• Full-track multiple-sector transfer capability without local processor intervention.
• High instantaneous (burst) data-transfer rates (up to 600MB per second).
• Native Command Queuing with command ordering to increase performance in demanding applications.
• Perpendicular recording technology provides the drives with increased areal density.
• PowerChoice™ for selectable power savings
• SeaTools™ diagnostic software performs a drive self-test that eliminates unnecessary drive returns.
• State-of-the-art cache and on-the-fly error-correction algorithms.
• Support for S.M.A.R.T. drive monitoring and reporting.
• Supports latching SATA cables and connectors.
• Tarnish-resistant components to help protect drive from environmental elements, increasing field reliability.
• Top Cover Attached motor for excellent vibration tolerance
• Worldwide Name (WWN) capability uniquely identifies the drive.
Note
Seagate recommends validating the configuration with the selected HBA/
RAID controller manufacturer to ensure use of full capacity is supported.

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.
The host adapter may, optionally, emulate a master/slave environment to host software where two
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.
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 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

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).

*One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.
**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.

2.5 Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 5 on page 24.
2.5.1 Power consumption
Power requirements for the drives are listed in Table 2 through Table 4. 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.
