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 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
the integrator to install a Serial ATA host adapter and Serial ATA disk drive in the current system and expect all 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.
The host adapter may, optionally, emulate a master/slave environment to host software where two
NOTE
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 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 International Organization: Serial ATA (Revision 3.0). The specification can be downloaded from
www.serialata.org.
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.

2.5 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 average of at least 5000 measurements of seeks between random tracks, less overhead.

Typical seek times (ms) Read
Track-to-track 1.5
Average 13.0
Average latency 5.6
These drives are designed to consistently meet the seek times represented in this manual. Physical
NOTE
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.

DRIVE SPECIFICATIONS
2.7 POWER SPECIFICATIONS
The drive receives DC power (+5V) through a native SATA power connector (refer to Figure 2).
2.7.1 Power consumption
Power requirements for the drives are listed in the table below. Typical power measurements are based on an average of drives tested,
under nominal conditions, at 25°C ambient temperature. These power measurements are done with Interface Power Management
modes like HIPM and DIPM enabled.
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 toward a specific position on the disk surface and does not execute a read or
write operation. Servo electronics are active. Seek mode power is measured based on three random seek operations every 100 ms.
This mode is not typical.
Read/write power and current
Read/write power is measured with the heads on track, based 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 the drive is not spinning, and the servo and read/write electronics are in powerdown mode.

1. 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.
2. Standby power is measured at steady state (after 200ms from transition)
