• High instantaneous (burst) data-transfer rates (up to 150 Mbytes per second).
• Giant magnetoresistiv e (GMR) recording heads and EPRML technology, provide the drives with increase d
areal density.
• State-of-the-art cache and on-the-fly error-correction algorithms.
• Full-track multiple-sector transfer capability without local processor intervention.
• Quiet operation.
• 800 Gs nonoperating shock and 250 Gs of operating shock.
• SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.
• The 3D Defense System™, which includes Drive Defense, Data Defense and Diagnostic Defense, offers the
industry’s most comprehensive protection for disc drives.
• Support for S.M.A.R.T. drive monitoring and reporting.
• Support for Read Multiple and Write Multiple commands.

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 c onfiguration with tru e plug-and- play conn ectivity. 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 A TA easy by providing legacy software support. Serial
ATA was designed to allow you t o install a Serial ATA host adapter and Serial ATA disc drive in your curren t
system and expect all of your existing applications to work as normal.
The Serial ATA interface co nnects each disc drive in a point-to-point c onfiguration with the Serial ATA host
adapter. There is no master/slave relationship with Seria l ATA devices like there is with para llel 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 essenti ally mean s both dr ives behav e as if they are Dev ice 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 repres ented to host so ftware as a Device 0 ( maste r) and
Device 1 (slave) acce ssed at the s ame set of ho st bus addr esses. A h ost adapter tha t emulat es a
master/slave environment manages two sets of shadow register s. This is not a typical Serial ATA
environment.
The Serial ATA host adapter and driv e shar e the funct ion of emul ating parall el ATA device beh avior to provid e
backward compatibility with existing host systems an d software. The Command and Contr ol 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 th e Shadow Register Block. A ll Se ri al ATA dev ic es beh av e l ike Device 0 devices . For add itional information about how Ser ial ATA emulates parallel ATA, refer to the “Serial ATA: High Speed Serialized
AT Attachment” specification. The specification can be downloaded from http://www.serialata.org.
