LAKE FOREST, Calif. - July 17, 2007 - Addressing the needs for the growing enterprise market for high-capacity, highly-reliable storage, Western Digital Corp. (NYSE: WDC) today announced it will be shipping its WD RE2 (RAID Edition) 750 GB hard drive this month. With 3.0 Gb/s data transfer rate, WD RE2 hard drives feature Native Command Queuing (NCQ) and 16 MB cache for high system performance.

"WD has continued to leverage its extensive experience from previous RAID Edition drives, to develop a hard drive perfectly suited for a variety of high-capacity enterprise applications. These drives demand high capacity, reliability, performance and advanced features," said Tom McDorman, vice president and general manager of enterprise storage, WD.

Combined with a new 750 GB capacity, this provides enterprise-class drives with reliability and other required attributes for demanding server and network-attached storage environments, such as file servers, e-mail servers and Web servers. Other proven features incorporated in the new WD RE2 750 GB hard drives include:
