MB, equals one million bytes. Your computer’s operating system may use a different standard of mea
surement 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. Seagate reserves the right to change,

2.1About 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 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.
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 content s of the traditional de vice 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 www.serialata.org.

Note.Th
ese 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.

3.8Power specifications
The drive receives DC power (+5V or +12V) through a na tive SATA power con nector. See Figure 3 on page 24.
3.8.1Power consumption
Power requirements for the drives are listed in the t able on p ag e 9. Typical power measurements are based on
an average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage 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 op erating
speed.
• Seek mode
During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and
does not execute a read or write operation. Servo electronics are active. Seek mode power represents the
worst-case power consumption, using only random seeks with read or write latency time. This mode is not
typical and is provided for worst-case information.
• Read/write power and current
Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-ms
delay, then a 16-sector read followed by a 32ms delay.
• Operating power and current
Operating power is measured using 40 percent random seeks, 40 per cent read/write mode (1 write for each
10 reads) and 20 percent drive idle mode.
• Idle mode power
Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads i n
a random track location.
• Standby mode
During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/
write electronics are in power-down mode.
