WD ships low-cost high-grade 4TB hard drive

From CNET News.com: Western Digital announced today the WD Se SATA 3.5-inch standard hard drive, which offers up to 4TB of storage space.

While it's not the first hard drive with this top capacity -- both WD and Seagate have had other 4TB hard drives -- WD says that the new WD Se is the first that's designed for scale-out data center deployments, yet is still affordable. The hard drive supports the latest SATA 3 (6Gbps) standard, comes with 64MB of cache memory, and spins at 7,200rpm.

According to WD, the new hard drive uses enterprise components and technologies to offer reliable always-on operation. For this reason, the new hard drive works best inside a storage system, such as a NAS server, where data needs to be available 24 hours a day, 365 days a year.

WD says the WD Se hard drive undergoes at least 5 million hours of functional and thermal testing and more than 20 million hours of additional testing under actual workloads in server and storage systems.

The new WD Se is available now in 2TB, 3TB, and 4TB capacities slated to cost between $160 and $310. The hard drive comes with a five-year warranty.
