Addressing a large and fast-growing segment of the storage industry and
demand for notebook-class hard drives from independent, high-volume suppliers,
Western Digital Corp. (NYSE: WDC) today introduced its WD Scorpio™
high-performance, low-power 2.5 inch hard drive for notebooks and other portable
digital devices. With its new product, WD is delivering the features and
industry-leading specifications that offer the greatest benefits to its
customers: high reliability, low power and fast performance.

Currently shipping in volume, WD Scorpio delivers fast 5,400 RPM spin speed and
12 ms seek time, yet operates with power requirements comparable to 4,200 RPM
drives yielding lower power consumption for longer battery life and increased
long-term reliability.

Applying its proven high quality manufacturing and superior service to new
market sectors, WD’s entry into the 2.5-inch segment significantly expands its
addressable markets by an estimated $ 4.6 billion a year.

According to research firm TrendFOCUS, 2.5-inch hard drives represent a
fast-growing segment of the hard drive market with unit shipments forecasted to
grow from 47 million units in 2003 to 60 million units in 2004, and the compound
annual growth rate of 2.5-inch hard drives is estimated to be 22.2 percent from
2003 through 2007.

"Western Digital’s 2.5-inch entry strategy centers on the highest-volume core of
the market," said John Donovan, vice president of research firm TrendFOCUS, an
industry analyst firm. "More than 80 percent of 2.5-inch drives sold now and in
the near future range in capacity from 40 to 80 gigabytes. WD has consistently
proven its ability to deliver the products and support that customers want in
high volume markets, making them a very capable contender for the growing
2.5-inch demand."

"WD’s entry into the mobile hard drive market is a significant strategic move to
increase the company’s opportunities for growth," said Arif Shakeel, president
and chief operating officer for Western Digital Corp. "Our operating model and
manufacturing efficiencies enable us to produce high quality, cost-effective
products in high volumes. Existing customers have been asking when WD would
enter the mobile market and, with the launch of the WD Scorpio product line, we
have delivered what they asked for."

WD Scorpio Exclusive Features

WD’s exclusive WhisperDrive™ technology with SoftSeek™ algorithms helps make WD
Scorpio the quietest 2.5 inch drive available on the market regardless of spin
speed. Leading-edge ShockGuard™ technology combines firmware and hardware
advancements to protect the drive mechanics and delicate platter surface to meet
the highest combined shock tolerance specifications (250 Gs while in operation,
900 Gs while idle) of any 2.5-inch drive in its class.

Additional shock protection by locking the heads off the disk is provided with
DuraStep Ramp™, which uses the most technologically advanced material available
on the market to allow the drive to execute a minimum of 600,000 load/unload
cycles without contamination. A rigid stainless steel cover withstands greater
than 5 pounds of pressure – nearly 1.5 times the industry average — without
pinching the motor hub or other internal components.

WD Scorpio’s lower power consumption leads to a cooler running drive, an
important factor contributing to increased hard drive reliability. Testing
performed by Western Digital’s Functional Integrity Testing Lab (FIT Lab™) shows
WD Scorpio runs cooler than competitors’ drives.

WD Scorpio mobile hard drives are offered in capacities of 40, 60 and 80 GB and
feature standard 2 MB cache and optional 8 MB cache; EIDE interface; and a
three-year warranty.
