Constellation.2 Serial ATA Product Manual, Rev. B 1

2.0 Introduction

This manual describes the functional, mechanical and interface specifications for the following Seagate Constellation.2

Serial ATA model drives:

Model Number Self-Encrypting Drive (SED) FIPS 140-2 Level 2 certified

ST91000640NS No No ST91000641NS Yes No ST91000642NS Yes Yes ST9500620NS No No ST9500621NS Yes No ST9500622NS Yes Yes ST9250610NS No No ST9250611NS Yes No ST9250612NS Yes Yes

Note. 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 encryp tion was necessary.

Note. The Self-Encrypting Drive models indicated on the cover of this product manual have provisio ns for

“Security of Data at Rest” based on the standards defined by the Trusted Computing G roup (see www.trustedcomputinggroup.org).

For more information on FIPS 140-2 Level 2 certification see See Section 5.0 on page 29. These drives provide the following key features:

• 7200 RPM spindle speed.

• High instantaneous (burst) data-transfer rates (up to 600MB/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 Queueing with command ordering to increase performance in demanding applications.

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

• Quiet operation.

• 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.

2 Constellation.2 Serial ATA Product Manual, Rev. B

Constellation.2 Serial ATA Self-Encrypting Drive models have the following additional features:

• Automatic data encryption/decryption

• Controlled access

• Random number generator

• Drive locking

• 16 independent data bands

• Cryptographic erase of user data for a drive that will be repurposed or scrapped

• Authenticated firmware download Note. There is no significant performance difference between Self-Encrypting Drive and standard (non-

Self-Encrypting Drive) models.

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 necessary to set any jump-

ers 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 content s of the traditional de vice 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.

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 7.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48-

bit addressing support of drives with capacities over 137 Gbytes.

3.6 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

• Average seek time is a true s tatistical random average of at le ast 5,000 measurements of seek s between r

andom tracks, less overhead.

*Typical seek times (ms) Read Write

Track-to-track 0.7 0.85 Average 8.5 9.5 Full Stroke 16.96 17.96

possible single-track seeks in both directions.

Average latency: 4.16

*Measured in performance mode. Note. T

hese 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.

3.8 Power specifications

The drive receives DC power (+5V or +12V) through a na tive SATA power con nector. See Figure 5 on page 26.

3.8.1 Power consumption

Power requirements for the drives are listed in the t able on pag e 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.

• 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.

The standard drive models and the SED drive models have identical hardware, however the security and encryption portion of the drive controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on the 12V supply.
