STORAGE VENDOR Western Digital has released its third generation 10,000 RPM 2.5in serial attached storage (SAS) hard disk drives.

In the midst of buying Hitachi's hard drive operations and trying to flog part of its business to Toshiba in order to please regulatory bodies, Western Digital announced that its S25 SAS hard drives have hit the shelves.

According to the firm the drives come in capacities of 300GB, 450GB, 600GB and 900GB and are designed for transaction processing and tiered storage arrays.

Darwin Kauffman, VP of enterprise storage solutions at Western Digital said, "Continuing our commitment to the industry's fastest-growing segment - 2.5-in drives - Western Digital is updating our small form factor SAS offering with the advanced technology of our third-generation drive, including a new 900 GB capacity point."

SAS drives have become extremely popular in edge servers where there are relatively modest capacity requirements but high data transfer rates. The drives also feature in tiered storage arrays that are usually comprised of solid state disk drives for high activity data and SAS hard disk drive units for the bulk of the storage space.

According to Western Digital, its S25 SAS drives use less than eight watts of power and have a 2 million hour mean time before failure rating. The firm said there are optional models that feature drive-level self encryption that meets the Trusted Computing Group's Enterprise Class A encryption standard. µ
