When referring to drive capacity one gigabyte, or GB, equals one billion bytes and one megabyte, or MB, equals one million 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 format ting and other functions, and thus will not be available for data storage.

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 normally 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 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 AT A ho st 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.

Note. The 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 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 adapte r cont ains a set of regi sters that shadow the conte nt s 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.

*One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment

2.2.1 LBA mode

When addressing these drives in LBA mode, all blocks (

sectors) are consecutively numbered from 0 to n–1,

where n is the number of guaranteed sectors as defined above. See Section 4.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48-

bit addressing support of drives with capacities over 137GB.

2.2.2 Solid State Hybrid feature

The Solid State Hybrid feature utilizes the addition of NAND Flash mem

ory 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 whic h monitors dr ive activity a nd determine s the optimu m data to maintain in the NAND Flash for peak respons iveness. 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

• Storage functionality is preserved with no dat

2.7 Seek time

Seek measurements are taken with nominal power at 25°C am bient 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

• Average seek time is a true statistical random average

random tracks, less overhead.

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

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.

2.9 Power specifications

The drive receives DC power (+5V) through a native SATA power connector.

2.9.1 Power consumption

Power requirements for the drives are listed in the t ab le on

page 8. T ypi cal powe r measur ements are based on

an average of drives tested, under nominal conditions, at 25°C ambient temperature.

• Spinup power

Spinup power is measured from the time of power-on to the

time that the drive spindle reaches operating speed.

• Seek mode

During seek mode, the read/write actuator arm moves towar

d a specific position on the disc surface and does not execute a read or write operation. Servo electronics a re active . Seek m ode p ower is measur ed based on three random seek operations every 100 ms. This mode is not typical.

• Read/write Read/write power is measured with the heads on track, ba

power and current

sed on three 63 sector read or write operations

every 100 ms.

• Idle mode power

Idle mode power is measured with the drive up to speed, with

servo electronics active and with the heads in

a random track location.

• Standby mode

During Standby mode, the drive accepts commands, but th

e drive is not spinning, and the ser vo and read/

write electronics are in power-down model
