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 information, visit www.bis.doc.gov), and controlled for import

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
the integrator to install a Serial ATA host adapter and Serial ATA disk drive in the current system 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
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.serialata.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.

2.5 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

These drives are designed to consistently meet the seek times represented in this manual. Physical
NOTE
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.
