and other demanding multimedia
applications.
Advanced Format
Technology
Leading edge technology delivers
improved video quality and AV
performance through enhanced
error correction capability.
SilkStream™technology
Optimized for smooth, continuous
digital video playback of up to five
simultaneous HD streams.
SilkStream is compatible with the
ATA streaming command set so AV
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.
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.
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.

1As 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 3 Gb/s transfer rate calculated according to the Serial ATA specification published by the SATA-
IO organization as of the date of this specification sheet. Visit www.sata-io.org for details.
2Maximum burst rate running the Mode 5 Ultra ATA transfer mode.
