WD Scorpio Black 320GB 2.5" Internal Hard Drive, 16MB Cache, SATA 3Gb/s Interface

The WD Scorpio Black 320GB 2.5" Hard Drive features ample storage, quiet operation, a 16 MB cache and low power consumption. With a 320GB storage capacity, SATA interface and transfer speeds up to 3 Gb/s, it's ideal for demanding mobile applications that require high performance. The Scorpio Black benefits from ShockGuard technology that protects the drive mechanics from impacts. It also uses SecurePark, 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 Scorpio Black is also tested rigorously to ensure compatibility with most systems.
