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.

1.0 Introduction

This manual describes the functional, mechanical and interface specifications for the following:
Seagate® BarraCuda® model drives:

Standard models Self-Encryption models

ST3000DM008 ST1000DM010 ST3000DM009

ST2000DM006 ST500DM009 ST2000DM007

Previous generations of Seagate Self-Encrypting Drive models were called Full Disk Encryption (FDE) models

Note

before a differentiation between drive-based encryption and other forms of encryption was necessary.

These drives provide the following key features:

• 7200 RPM spindle speed.

• Compliant with RoHS requirements in China and Europe.

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

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

• Native Command Queuing with command ordering to increase performance in demanding applications.

•Quiet operation.

• Seagate AcuTrac™ servo technology delivers dependable performance, even with hard drive track widths of only 75
nanometers.

• Seagate OptiCache™ technology boosts overall performance by as much as 45% over the previous generation.

• Seagate SmartAlign™ technology provides a simple, transparent migration to Advanced Format 4K sectors

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

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

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

• Supports latching SATA cables and connectors.

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

• Worldwide Name (WWN) capability uniquely identifies the drive.

www.seagate.com Introduction

1.1 About the SATA interface

The Serial ATA (SATA) 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, SATA makes the transition from parallel ATA easy by providing legacy software support. SATA was designed to
allow users to install a SATA host adapter and SATA disk drive in the current system and expect all of the existing
applications to work as normal.

The SATA interface connects each disk drive in a point-to-point configuration with the SATA host adapter. There is no
master/slave relationship with SATA devices like there is with parallel ATA. If two drives are attached on one SATA 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 SATA 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 SATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as
the Shadow Register Block. All SATA devices behave like Device 0 devices. For additional information about how SATA
emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA Revision 3.2”. The specification can be
downloaded from www.sata-io.or

g.

Note

The host adapter may, optionally, emulate a master/slave environment to host software where two
devices on separate SATA 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 SATA environment.

The AFR specification for the product assumes the I/O workload does not exceed the average
annualized workload rate limit of 55 TB/year. Workloads exceeding the annualized rate may
degrade the product AFR and impact reliability as experienced by the particular application.
The average annualized workload rate limit is in units of TB per calendar year.

* All specifications above are based on native configurations.
** One GB equals one billion bytes and 1TB equals one trillion bytes when referring to hard drive capacity.

Accessible capacity may vary depending on operating environment and formatting.

*** 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.

† Seagate does not recommend operating at sustained case temperatures above 60°C.

Operating at higher temperatures will reduce useful life of the product.

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 1.0 1.2

Average 8.5 9.5

Average latency 4.16

These drives are designed to consistently meet the seek times represented in this manual. Physical seeks,

Note

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.
