The Western Digital 320GB WD Caviar Blue SATA 3.5" Hard Drive features ample storage, quiet operation and low power consumption. With a 320GB storage capacity, SATA interface and transfer speeds up to 6 Gb/s, it's ideal for demanding desktop applications that require high performance. The Caviar Blue benefits from ShockGuard technology that protects the drive mechanics from shocks. It also uses NoTouch, which prevents the recording heads from resting on the disk during spin up, spin down, and when the drive is off. This results in a more reliable drive due to the limited head wear. The Caviar Blue is also tested rigorously to ensure compatibility with most systems.
