1.0Introduction

This manual describes the functional, mechanical and interface specifications for the following Seagate Barracuda® 7200.12 Serial ATA model drives:

ST31000528AS	ST3500418AS	ST3320418AS	ST3160318AS
ST3750528AS	ST3500410AS	ST3250318AS

These drives provide the following key features:

•7,200 RPM spindle speed.

•High instantaneous (burst) data-transfer rates (up to 300 Mbytes per second).

•Perpendicular recording, Tunneling Magnetoresistive (TMR) recording heads and EPRML technology, for increased areal density.

•State-of-the-art cache and on-the-fly error-correction algorithms.

•Native Command Queueing with command ordering to increase performance in demanding applications.

•Full-track multiple-sector transfer capability without local processor intervention.

•Quiet operation.

•Compliant with RoHS requirements in China and Europe.

•SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.

•Support for S.M.A.R.T. drive monitoring and reporting.

•Supports latching SATA cables and connectors.

•Worldwide Name (WWN) capability uniquely identifies the drive.

1.1About 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 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 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 2.6”. The specification can be downloaded from www.sata-io.org.
