SATA Hard Drives

WD AV hard drives take advantage of significant design 

advances in WD's storage technology by incorporating 

SilkStream

™

 streaming with whisper-quiet acoustics and 

thermally optimized operation. These design advances, 

coupled with 7200 RPM performance enable unparalleled 

reliability and low cost of ownership for manufacturers of 

digital video recording devices that require 24x7 reliability.

SATA 6 Gb/s

3.5-inch/1-inch

7200 RPM

80 GB to 500 GB

With a MTBF of 1 million hours, 
these drives are designed to last in 
always-on streaming digital 
audio/video environments such as 
PVR/DVR, DVR recorders, and 
surveillance video recorders.

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

Tested for compatibility in a broad 
range of AV products including set 
top boxes, DVD recorders, and 
mainstream surveillance systems.

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

™

The recording head never touches 
the disk media ensuring significantly 
less wear to the recording head and 
media as well as better drive 
protection in transit.

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

Best-in-class reliability for 
mainstream 3.5-inch form-factor AV 
storage.***

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

** Assumes Host Transfer Block size of 2 MB per stream.

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