2.1 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
any jumpers or other configuration options.
• Thinner and more flexible cabling for improved enclosure airflow and ease of installation.
• Scalability to higher performanc
e levels.
In addition, Serial ATA makes the transition from parallel ATA easy by providing legacy software support. Serial
A
TA was designed to allow you to install a Serial ATA host adapter and Serial ATA disc drive in your current
system and expect all of your existing applications to work as normal.
The Serial ATA interface connects each disc 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.
connectivity. It is not normally necessary to set
Note. Th
e host adapter may, optionally, emulate a master/slave environment to host software where two
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 and drive share the function o
f 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 http://www.serialata.org.

3.2.1 LBA mode
When addressing these drives in LBA mode, all blocks (s
ectors) are consecutively numbered from 0 to n–1,
where n is the number of guaranteed sectors as defined above.
See Section 5.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48bit addressing support of drives with capacities over 137GB.
3.2.2 Solid State Hybrid feature
The Solid State Hybrid feature utilizes the addition of
NAND Flash memory to enhance the performance of the
drive. Short random accesses to the NAND Flash are faster than disc accesses due to the elimination of seek
and rotational latencies and therefore it is used to store more frequently accessed data. The Momentus XT
uses a proprietary algorithm which monitors drive activity and determines the optimum data to maintain in the
NAND Flash for peak responsiveness. The Solid State Hybrid feature is self contained in the drive firmware
and functions independent of the host hardware or operating system. There are no special host system
requirements. Momentus XT can be installed in any standard SATA environment and will automatically optimize.
Specifics of the Solid State Hybrid Feature:
• Powerful ECC correction on data read from the NAND Flash.
• Maintains a list of defective NAND Flash blocks and maps them out of use.
• Additional bad blocks added during us
• Storage functionality is preserved with no data
e will be added to the list of defective blocks and taken out of use.

• No user intervention required.
