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

ST32000645NS No No

These drives provide the following key features:

• 7200 RPM spindle speed.

• 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 your configuration with the selected HBA/RAID controller manufacturer to

ensure full 3TB capacity capabilities.

CONSTELLATION ES.2 SERIAL ATA PRODUCT MANUAL, REV. H 3

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 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: High Speed Serialized AT Attachment” specification. The specification can be downloaded from
www.serialata.org.

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.

2.6 SEEK TIME

Seek measurements are taken with nominal power at 25°C ambient 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 possible single-track seeks in both directions.

• Average seek time is a true statistical random average of at least 5000 measurements of seeks between random tracks,
less overhead.

*TYPICAL SEEK TIMES (MS) READ WRITE

Track-to-track 0.50 0.50

Average 8.5 9.5

Average latency: 4.16

*Measured in performance mode.

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.

2.8 POWER SPECIFICATIONS

The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 4 on page 22.

2.8.1 Power consumption

Power requirements for the drives are listed in the table on page 9. 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.

• 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 toward a specific position on the disc surface and does not execute
a

read or write operation. Servo electronics are active. Seek mode power represents the worst-case power consumption,
using only random seeks with read or write latency time. This mode is not typical and is provided for worst-case informa­tion.

• Read/write power and current

Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-ms delay, then a 16­sector read followed by a 32ms delay.

• Operating power and current

Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each 10 reads)
and 20 percent drive idle mode.

• Idle mode power

Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random
track location.

• Standby mode

During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/write electron­ics are in power-down mode.
