Western Digital Corp. (NYSE: WDC) today announced a new family of hard drives
for audio and video recording products, one of today’s fastest growing digital
storage markets. Drawing on its expertise as a leading supplier to major
consumer electronics and surveillance manufacturers worldwide, WD has designed
its new 3.5-inch WD AV hard drives with technologies that provide the increased
reliability, cooler and quieter operation and low power consumption required for
these demanding environments. The WD AV drives in capacities ranging from 80 GB
to 500 GB are available through the company’s distribution network.

"WD has been a high-volume supplier of best-in-class drives to our video
recording OEM customers since the digital video recording market was in its
infancy," said Jim Welsh, vice president and general manager, Branded Products
and Consumer Business units. "As the market for drives designed specifically for
these applications has expanded, so has the number of end-product manufacturers
worldwide. The best way to serve this diverse and growing customer base is to
offer our new WD AV drive directly and through our distribution network."

WD AV Hard Drives
The high capacities, high reliability and cost effectiveness of hard drive
technology have enabled a range of audio and video recording applications,
including digital set-top boxes, personal video recorders, IP gateways and
mainstream surveillance systems. These applications, which often demand 24×7
operation from hard drives, have different requirements than personal computers,
such as higher reliability, universal compatibility, low power consumption and
the ability to simultaneously record multiple audio and/or video streams.
Consumer applications such as set-top boxes and DVD recorders place additional
demands on hard drives to consume less power, generate less heat and operate
quietly.

Reliability That Can Be Counted On
With advanced features, WD AV hard drives are built specifically to operate in
24×7 environments, where the drive is always on, streaming audio and video
content. WD AV drives are rated for reliability at one million hours MTBF, which
is higher than standard desktop drives.

WD AV drives incorporate WD’s ramp load feature, which parks the recording heads
off the disk surface during spin up, spin down and when the drive is not
operating. Contrary to drives without ramp load, the feature in WD AV drives
improves non-operational shock tolerance and ensures that the recording head
never touches the disk surface, reducing head and surface wear and enhancing
long-term reliability.

WD’s preemptive wear leveling (PWL) frequently sweeps the drive arm across the
disk to reduce uneven wear on the drive surface, which is common in
audio-video-streaming applications.

Smart Power Reduction
WD’s unique IntelliSeek™ technology proactively calculates an optimum seek speed
to eliminate hasty movement of the actuator that produces noise and requires
power, which is common in other drives. With IntelliSeek, the actuator’s
movement is controlled so the head reaches the next target sector just in time
to read the next piece of information, rather than rapidly accelerating and
waiting for the drive rotation to catch up. This smooth motion reduces power
usage of WD AV hard drives by more than 60 percent compared with standard
drives, as well as quiets seek operation and lowers vibration. Additionally, the
ramp load feature reduces power consumption during spin up and the drive’s
electronics have been optimized to save power for audio and video applications.

Quiet as a Mouse
In addition to the sound-reducing properties of IntelliSeek and ramp load, WD
utilizes multi-stage formed stainless steel top covers and precision-designed
base castings that minimize sound levels for consumer sound-sensitive
applications. The result is WD AV drives emit less than one sone, which is
virtually below the threshold of human hearing.

High Definition Multitasking
Smooth audio-video recording and playback of today’s high-definition content is
essential for consumer PVR applications. The SilkStream™ technology in WD AV
drives effortlessly delivers those qualities in as many as 12 simultaneous
high-definition streams1 and is based on the industry-standard ATA specification
for universal compatibility. Mainstream surveillance video recorders save images
at a slower pace than high-definition video, and in that application WD AV hard
drives record up to 16 standard-definition streams.

Compatibility
To ensure broad compatibility, WD AV drives have been tested in a wide range of
audio and video products including set-top boxes, DVD recorders and mainstream
surveillance systems.

WD AV drives are currently available with EIDE and SATA interfaces in capacities
ranging from 80 GB to 500 GB through WD’s worldwide distribution network.
