Product Overview

Western Digital HC320 SAS 12Gb/s Hard Drive:

Rotational Vibration Safeguard (RVS) technology utilizes sophisticated electronics to monitor the drive and correct both linear and rotational vibration disturbances in real time especially helpful in multi-drive arrays and rack-mounted systems maintaining high read/write performance. Ultrastar DC HA200 series is offered with a SATA 6 Gb/s interface and native 512-byte (512n) sector size for compatibility with legacy data center applications.
