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 si ze, file format, features and application software. Actual data rates may var y 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 more

This manual describes the functional, mechanical and interface specifications for the following:

• Tarnish-resistant components to help protect drive from environmental elements, increasing field reliability
• Worldwide Name (WWN) capability uniquely identifies the drive.
1.1About 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 current systems and expect all 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
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.
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.or
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.
Unless otherwise noted, all specifications are measured under ambient conditions, at 25°C, and nominal power. For convenience, the
phrases the drive and this drive are used throughout this manual to indicate the following drive models:.

Average rate of <550TB/year
The MTBF specification for the drive assumes the I/O workload does not exceed the Average Annualized Workload
Rate of <550TB/year. Workloads exceeding the annualized rate may degrade the drive MTBF and impact product
reliability. The Average Annualized Workload Rate is in units of TB per year, or TB per 8760 power on hours. Work
load Rate = TB transferred * (8760 / recorded power on hours).

*All specifications above are based on native configurations.
** One GB equals one billion bytes and 1TB equals one trillion 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.
†Seagate does not recommend operating at sustained case temperatures above 60°C.
Operating at higher temperatures will reduce useful life of the product.
