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 Queuing 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.

Self-Encrypting Drive

(SED) models

Note

Note

Note

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

Previous generations of Seagate Self-Encrypting Drive models were called Full
Disk Encryption (FDE) models before a differentiation between drive-based
encryption and other forms of encryption was necessary

The Self-Encrypting Drive models indicated on the cover of this product manual
have provisions for “Security of Data at Rest” based on the standards defined by
the Trusted Computing Group (see www.trustedcomputinggroup.org).

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 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

Note

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: High Speed Serialized AT Attachment” specification. The

specification can be downloaded from www.serialata.org.

2.2.1 LBA 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 5.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48-bit addressing
support of drives with capacities over 137GB.

2.5 Power specifications

The drive receives DC power (+5V and +12V) through a native SATA power connector. See Figure 4 on page 25.

2.5.1 Power consumption

Power requirements for the drives are listed in Table 2 and Table 3. 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.

Operation at 3 Gb mode reduces the +5V supply load by 3mA with a commensurate power reduction of 15mW.

Note

There is no measurable impact to the 12V supply load when running at lower interface speeds.

*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.
