Western Digital Corp., a world leader in hard disk drive production, on Monday announced WD XE, a 10 000rpm hard drive in 2.5” form-factor that comes mounted in a 3.5” adapter. The WD XE hard drives provide best-in-class performance, low power consumption, and an easier upgrade path for existing 3.5” storage systems.


The WD XE SAS enterprise hard drives in 3.5” performance adapters, shipping in 300GB, 600GB and 900GB capacities (models: WD3001HKHG, WD6001HKHG, and WD9001HKHG); are available through select distributors and resellers. Eventually, WD will also make available 450GB version of the drive (WD4501HKHG) All the drives offer 2 million hours MTBF.

WD XE 3.5” hard drives with 32MB cache and 10 000rpm spindle speed deliver up to 67% lower power versus 3.5” 15 000rom drives, which can result in substantially lower total cost of ownership (TCO) while increasing capacity and reliability. WD XE delivers 6Gb/s interface transfer rates, best-in-class sequential data rate of 204 MB/s, and outstanding random I/O performance, according to Western Digital.

The WD XE also comes with dual port, full duplex connectivity, which offers higher reliability, performance and data availability by eliminating single points of failure, designed for high-availability datacenter system.

WD XE comes with NoTouch ramp load technology, the recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.

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

While demand for 3.5”, 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.

Manufacturer’s suggested retail price (MSRP) for the WD XE hard drives in performance adapters range from $229.99 to $599.99 USD. WD XE drives are covered by a five-year limited warranty.
