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 jump-
ers 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 disk drive in your current
system and expect all of your 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.
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 adapter contains a set of registers that shadow the contents of the traditional device regis-
ters, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For addi-
tional information about how Serial ATA emulates parallel ATA, refer to the Serial ATA International
Organization: Serial ATA Revision 2.6”. The specification can be downloaded from www.sata-io.org.

When addressing the drive 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.

2.6 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 avera
ge of at least 5,000 measurements of seeks between
random tracks, less overhead.
Typical seek times (ms) Read Write
Track-to-track <1.0 <1.2
Average <14.0 <15.0
*Measured in performance mode.
**Measured in quiet mode.
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.

2.8 Power specifications
The drive receives DC power (5V or 12V) through a native SATA power connector. Refer to Figure 2 on
page 22.
2.8.1 Power consumption
Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on
a
n average of drives tested, under nominal conditions, using 5V and 12V input voltage at 25°C ambient tem-
perature.
Spinup power
Spinup power is measured from the time of power-on to
the time that the drive spindle reaches operating
speed.
Idle mode power
Idle mode power is measured with the drive up to speed, with ser
vo electronics active and with the heads in
a random track location.
Operating (CE seek profile)
Operating power is measured by simulating a typical PVR op
erating environment, using a 50% write, 50%
read algorithm.
Standby mode
During Standby mode, the drive accepts commands, but th
e drive is not spinning, and the servo and read/
write electronics are in power-down mode.
Table 4: DC power requirements

Operating 4.107 0.295 0.219
Standby 0.699 0.121 0.008
Sleep 0.811 0.131 0.012
*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and
power to operational levels.
Note. Drive supports PHY layer power management. When enabled, a power savings of ~300mw can be
achieved in Idle, Standby and Sleep modes.
