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 more

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.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 3.0”. The specification can be downloaded from www.sata-io.org.
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.
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:

Annualized Failure Rate (AFR)0.55%
Average annualized workload rating: <180 TB/year.
The AFR specification for the product assumes the I/O workload does
not exceed the average annualized workload rate limit of 180 TB/year.
Rated Workload
Workloads exceeding the annualized rate may degrade the product AFR
and impact reliability as experienced by the particular application.
The average annualized workload rate limit is in units of TB per calendar
year.
