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

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 users to install a Serial ATA host adapter and Serial ATA disk drive in the current system and expect all of
the existing applications to work as normal.
The Serial ATA interface connects each disk 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.
The host adapter may, optionally, emulate a master/slave environment to host software where two devices on
Note
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
International Organization: Serial ATA Revision 3.2”. The specification can be downloaded from www.sata-io.org.
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.

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.
3TB & 2TB 1TB
Typical seek times (ms) Read Write Read Write
Track-to-track <1.0 <1.2 <1.0 <1.2
Average <8.5 <9.0 <8.5 <9.0
Average latency 5.1 5.1 5.1 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.

2.8 Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. (Refer to Figure 3).
2.8.1 Power consumption
Power requirements for the drives are listed in Table 3 on page 12. 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 (CE profile)
Operating power is measured by simulating a typical PVR operating environment, using a 50% write, 50% read algorithm.
• 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.
