Western Digital Unveils 4 Terabyte WD RE SAS and SATA Drives, Eyes Public and Private Clouds

Western Digital has announced a line of SAS and SATA hard drives designed for both the consumer and enterprise markets, and they’re designed for high-capacity and longevity.

The 3.5-inch, 7,200RPM WD RE SATA drives are available in capacities of 2TB, 3TB, and 4TB capacities, and the SAS drives come in 1TB, 2TB, 3TB, or 4TB. Western Digital sees the drives as ideal for public and private cloud environments.

The higher storage density allows companies to include more storage capacity in a smaller footprint, which is always a plus, and the drives are designed to last, thereby cutting down on lifecycle management costs.


The drives boast reliability features including 1.4M hours MTBF and 1.2M hours MTBF (for the SAS and SATA drives, respectively), NoTouch road lamp technology so the heads never touch the disk, Dual Stage Actuation (DSA) and Rotary Acceleration Feed Forward (RAFF).
