When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your computer’s operating system may use a different standard of measurement and report a lower capacity. In addition, some of the listed capacity is used for formatting and other functions, and thus will not be available for data storage. Actual quantities will vary based on various factors, including file size, file format, features and application software. Actual data rates may vary depending on operating environment and other factors. The export or re-export of hardware or software containing encryption may be regulated by the U.S. Department of Commerce, Bureau of Industry and Security (for more information, visit www.bis.doc.gov), and controlled for import and use outside of the U.S. Seagate reserves the right to change, without notice, product offerings or specifications.

These drives provide the following key features:

•7200 RPM spindle speed.

•128 MB data buffer.

•PowerChoice™ for selectable power savings

•Top Cover Attached motor for excellent vibration tolerance

•High instantaneous (burst) data-transfer rates (up to 600MB per second).

•Perpendicular recording technology provides the drives with 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.

•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.

Note	Seagate recommends validating the configuration with the selected HBA/RAID
	controller manufacturer to ensure use of full capacity is supported.

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 users to install a Serial ATA host adapter and Serial ATA disk drive in the current system and expect all of the 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 devices

on separate Serial ATA ports are represented to host software as a Device 0 (master) and Device 1 (slave) Note 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: High Speed Serialized AT Attachment” specification. The specification can be downloaded from www.serialata.org.

*One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.

2.2.1LBA mode

When addressing these drives 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.

See Section 6.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48-bit addressing support of drives with capacities over 137GB.

2.5Power specifications

The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 8 on page 22.

2.5.1Power consumption

Power requirements for the drives are listed in Table 2 through Table 4. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature.
