WD XE SAS 10K RPM Hard Drives Now Available
Published on May 15th, 2013
Western Digital has released a new SAS hard drive for enterprise and server use, called the WD XE SAS hard drive. It’s an enterprise class hard drive with 10,000 RPM spindle speed and 6Gbps SAS interface. The main drive has a 2.5-inch form factor. But a WD XE 3.5-inch is also available, which is the mounted version of this drive. It basically looks like the WD Velociraptor, but instead of a Serial ATA interface, it’s using Series Attached SCSI connectivity. Check out more details below and where you can get one.
Western Digital claims that the WD XE consumes up to 67% lesser power consumption compared to the 15,000 RPM rivals. However the WD XE lacks in variety of storage capacity. It’s only available in 300GB, 600GB and 900GB. Unlike the Velociraptor which has a 1TB version, and the WD RE Enterprise drives that has a 4TB storage capacity.
