WD(R) Adds 2 TB Hard Drives to Meet Demands for Today's AV/Surveillance Markets

WD AV-GP Hard Drives with WD GreenPower Technology(TM) Provide Cooler, Quieter
Operation with Lower Power Consumption

LAKE FOREST, Calif., May 19 /PRNewswire-FirstCall/ -- As demand for higher
capacity storage continues to increase due to large video applications,
including high-definition video, WD(R) (NYSE: WDC) today expanded its WD AV-GP
line of hard drives to include a 2 TB capacity, the industry's largest
available drive to-date. WD AV-GP hard drives with WD GreenPower
Technology(TM) provide cooler and quieter operation and lower power
consumption.

Designed to withstand the stringent environment of the surveillance and
security markets, the WD AV-GP line of hard drives for audio and video
applications reduces power consumption by as much as 40 percent over standard
drives in their respective classes. The new WD AV-GP 2 TB hard drive is
perfect for applications such as DVRs (digital video recorders), media
centers, media servers, as well as surveillance video recording that demand a
higher capacity hard drive and exceptional reliability.

"Our consumer electronics customers require hard drives that consume less
power, generate less heat and operate quietly," said Jim Welsh, senior vice
president and general manager of WD's branded products and consumer
electronics groups. "Audio and video recording applications, such as DVRs,
media servers, media centers and mainstream surveillance systems, often demand
24x7 operation from hard drives. Our drives meet the demanding requirements of
these markets including higher reliability, universal compatibility, low power
consumption and the ability to simultaneously record multiple audio and/or
high-definition video streams."

AV Intelligent Drive Technology
Following are several features of the WD AV-GP line of hard drives:

-- Long-term Reliability - Designed to last in high-temperature always-on
streaming digital audio/video environments such as PVR/DVR recorders
and
surveillance video recorders.
-- Quiet - Noise levels have been minimized to less than one sone(1) -
virtually below the threshold of human hearing.
-- Reduced Power Consumption - With the combination of WD's
IntelliSeek(TM), IntelliPark(TM), and IntelliPower(TM) technologies,
WD
has reduced power consumption by up to 40 percent compared to
competitors' drives.
-- IntelliPark - Delivers lower power consumption by automatically
unloading the heads during idle to reduce aerodynamic drag.
IntelliPark
improves non-operating shock characteristics, providing enhanced
robustness in environments where excessive transportation and handling
occurs.
-- Compatible - Tested for compatibility in a broad range of AV products
including set-top boxes, DVD recorders and mainstream surveillance
systems.
-- SilkStream(TM) - Optimized for smooth, continuous digital video
playback
of up to 12 simultaneous HD streams. SilkStream is compatible with the
ATA streaming command set so CE customers can use standard streaming
management and error recovery options.

-- 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.
