Product Features

24x7 reliability

These drives are designed to
last in high temperature always­on streaming digital audio/video
environments such as PVR/DVR,
IPTV, and video surveillance systems.

Advanced Format technology

Leading edge technology delivers
improved video quality and AV
performance through enhanced error
correction capability.

WIDTH/HEIGHT

2.75 in./0.27 to 0.37 in.
(69.85 mm/6.8 to 9.5 mm)

SilkStream™ technology

Optimized for smooth, continuous
digital video playback of up to ve
simultaneous HD streams. SilkStream
is compatible with the ATA streaming
command set so CE customers can
use standard streaming management
and error recovery options.

Ultra-cool operation

A cool drive is a more reliable drive.
WD continues to develop new and
innovative ways to keep drives cool
while they are operating.

ROTATIONAL SPEED

5400 RPM

Quiet

Noise levels have been minimized to
less than one sone* - virtually below
the threshold of human hearing.

Low power consumption

The drive draws less than 2 Watts
while operating and a mere 4.75
Watts during spin up.

CAPACITIES

160 GB to 1 TB

Note: Not all products may
be available in all regions of
the world.

1 million hours MTBF

Best-in-class reliability for small
form-factor AV storage.**

Preemptive Wear Leveling
(PWL)

The drive arm frequently sweeps
across the disk to reduce uneven
wear on the drive surface common to
audio video streaming applications.

* A sone is a subjective unit of loudness as perceived by a person
with normal hearing.

** Based upon dual tuner system operating in typical 30°C air ambient
environment.

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer

rate or interface, megabyte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 6 Gb/s transfer rate calculated according to the Serial ATA specication published by the SATA-IO organization as of the date of this specication
sheet. Visit www.sata-io.org for details.
