Momentus Product Manual, Rev. C 1

2.0 Introduction

This manual describes the functional, mechanical and interface specifications for the following Seagate Momentus

model drives:

4K byte/sector models

• ST9640322AS • ST9400321AS • ST9320312AS

512 byte/sector models

• ST9640320AS • ST9320310AS • ST9160316AS

• ST9500320AS • ST9250310AS •

These drives provide the following key features:

• 5400-RPM spindle speed.

• 8-MB buffer.

• Quiet operation. Fluid Dynamic Bearing (FDB) motor.

• High instantaneous (burst) data-transfer rates (up to 3.0 Gb/s).

• Perpendicular recording technology provides the drives with increased areal density.

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

• Native Command Queuing (NCQ) with command ordering.

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

• 1000 Gs nonoperating shock and 350 Gs of operating shock.

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

• The 3D Defense System™, which includes Drive Defense, Data Defe nse and Diagnostic Defense, of fers the industry’s most comprehensive protection for disc drives.

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

• Support for Read Multiple and Write Multiple commands.

2.1 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 op tio ns .

• 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 devi ce 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 http://www.serialata.org.
