IRVINE, Calif., April 22, 2013

IRVINE, Calif., April 22, 2013 /PRNewswire/ --WD^®, a Western Digital
(NASDAQ: WDC) company and a world leader in storage, today announced a new
3.5-inch SAS hard drive solution for legacy datacenter storage systems with
the release of the WD XE™, 2.5-inch, 10,000 RPM SAS hard drive, now available
mounted in a 3.5-inch WD performance adapter. Shipping immediately, the WD XE
hard drives provide best-in-class performance, low power consumption, and an
easier upgrade path for existing 3.5-inch storage systems.

While demand for 3.5-inch, high-performance enterprise-class hard drives
slows, a need remains for an alternate high-performance storage device as a
transitional solution for legacy systems. WD XE hard drives offer
best-in-class sequential performance and provide a compelling upgrade for
datacenters migrating away from legacy drives nearing end-of-life.

"Delivering up to 50 percent higher capacity, similar or better maximum
sequential performance, higher reliability and up to 67 percent lower power
consumption versus 3.5-inch, 15,000 RPM drives, the new WD XE drives are the
answer for data center server and storage solutions needing a transition
strategy," said Rich Rutledge, senior vice president of WD's datacenters
business unit. "IT managers now have a worry-free migration path to the latest
enterprise performance drives from WD, while preserving their chassis and
solution investments."

WD XE 2.5-inch SAS hard drives in 3.5-inch performance adapters feature:

Highest performance in its class – WD XE delivers ultra-fast 6 Gb/s transfer
rates, best-in-class sequential data rate of 204 MB/s, and outstanding random
I/O performance;

Low power consumption – This 3.5-inch SAS drive delivers up to 67 percent
lower power versus 3.5-inch 15,000 RPM drives, which can result in
substantially lower total cost of ownership (TCO) while increasing capacity
and reliability;

Form factor – 2.5-inch drive mounted in 3.5-inch performance adapter for ease
of upgrade and ultra-cool operation;

Dual port, full duplex connectivity – Offers higher reliability, performance
and data availability by eliminating single points of failure, designed for
high-availability datacenter systems;

media ensuring significantly less wear to the recording head and media as well
as better drive protection in transit; and
