Western Digital, which makes desktop, mobile and high-capacity enterprise hard drives, is offering its second-generation WD S25 SAS drives and its latest WD RE SAS 3.5-inch drives for the traditional enterprise market.

Shipping now, the 2.5-inch, 10,000 RPM, WD S25 with SAS 6 Gb/s interface hard drives offer IT professionals expanded storage with new 450 GB and 600 GB capacities. The WD S25 line, including the previously released 147 GB and 300 GB capacities, is designed for mission-critical server and storage systems. It was announced Jan. 18.

Features include RAFF (Rotary Acceleration Feed Forward), which optimizes operation and performance when the drives are used in vibration-prone, multi-drive chassis and requires less than 8 watts to operate. NoTouch ramp load technology assures the recording head never touches the disk media, and in addition to being ROHS (Restriction of Hazardous Substances) compliant, these drives also incorporate a halogen-free design. Like all of the company’s enterprise storage hard drives, WD S25 carry a standard five-year limited warranty worldwide.

Also shipping now to OEMs (original equipment manufacturers) is the new 3.5-inch, 7,200 RPM, WD RE SAS with 6 Gb/s interface hard drives, which offer 1 TB and 2 TB capacity points, and represent what the company called “a key addition” to WD’s expanding enterprise product portfolio. The company also said the WD RE SAS drives mark an important commitment to the expansion of WD’s SAS portfolio for high-capacity data center storage, SANs (storage area networks), NAS (network-attached storage), DAS (direct-attach storage), networked surveillance systems and cloud storage.
