Seagate Desktop HDD Product Manual, Rev. F 1
1.0 Introduction
This manual describes the functional, mechanical and interface specifications for the following
Seagate® Desktop HDD model drives:
ST4000DM000 ST3000DM003
These drives provide the following key features:
• High instantaneous (burst) data-transfer rates (up to 600MB per second).
• TGMR 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.
• 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
• Quiet operation.
• Compliant with RoHS requirements in China and Europe.
• 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.
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 SA TA 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 3.0”. The specification can be downloaded from www.sata-io.org.
The host adapter may, optionally, emulate a master/slave environment to host software where two
Note
Seagate Desktop HDD Product Manual, Rev. F 2
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.

Rated workload
55TB/year. Workloads exceeding the annualized rate may degrade the drive
AFR and impact product reliability. The average annualized workload rate limit
is in units of TB per year, or TB per 8760 power-on hours. Workload rate limit =
TB transferred × (8760/recorded power-on hours).

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 12.0 12.0
Average latency 5.1
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.
