WD announces new 3,5-inch SAS hard drives

Apr 29, 2013

WD, a Western Digital company, has announced a new 3,5-inch SAS hard drive solution for legacy data centre 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.

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 data centres migrating from legacy drives nearing end-of-life.

“Delivering up to 50% higher capacity, similar or better maximum sequential performance, higher reliability and up to 67% lower power consumption versus 3,5-inch,15 000 RPM drives, the new WD XE drives are the answer for data centre server and storage solutions needing a transition strategy,” says Rich Rutledge, senior VP of WD’s data centres 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 6Gbps transfer rates, a best-in-class sequential data rate of 204Mbps, and outstanding random I/O performance;

* Low power consumption – this 3,5-inch SAS drive delivers up to 67% 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 a 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. It is designed for high-availability data centre systems;

* 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; and

* Industry’s highest reliability rating – two million hours mean time before failure (MTBF).
