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

Seagate FireCuda Product Manual, Rev. E 5

1.0 Introduction

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

ST2000DX002 ST1000DX002

These drives provide the following key features:

• 7200 RPM spindle speed

•8GB NAND flash

• 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

• 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.

• Scalability to higher performance levels.

• Thinner and more flexible cabling for improved enclosure airflow and ease of installation.

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

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

Note

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.

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 4.3.1, "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 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.

2.7 Start/stop times

Time-to-ready may be longer than normal if the drive power is removed without going through normal OS powerdown
procedures.

Power-on to ready* (in seconds) <1

Standby to ready* (in seconds) <1

Ready to spindle stop (in seconds) 10 (typical) / 11 (max)

* Hybrid time-to-ready specification assumes all needed data files are pinned to flash, Windows 8 environment, and fast BIOS implemented

2.8 Power specifications

The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to Figure 1 on page 21.

2.8.1 Power consumption

Power requirements for the drives are listed in Table 1, 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.

• Spinup power
Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.

• 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
16-sector read followed by a 32-ms 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.
