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

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

Power dissipation (2 disk models) Avg (watts 25° C) Avg 5V typ. amps Avg 12V typ. amps

Spinup — — 2.0 (peak)

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.
