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 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 traditio nal device regi s­ters, 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.

**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.
***Typical notebooks will pull power to the drive when entering S3 and S4; while in the S3 and S4 states, drive sleep and drive standby

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.

Typical seek times (msec) Read
Track-to-track 1.5 Average 11.0 Full-stroke 22.0 Average latency 4.17
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 msecs. This mode is not typical.
