The high performance 320 GB Scorpio Black SATA 2.5" Internal Drive from WD is ideal for compact desktops, external hard drives and gaming system. It is designed to give you top notch capacity and speed required to supercharge a notebook PC without compromising on battery life or quiet acoustics.

Desktop-Class Performance for Notebook Computers
With 7200 RPM spin speed, 16 MB cache, and capacity up to 320 GB, these drives enable you to have the best of both worlds: the capacity and performance of a desktop PC with the convenience and portability of a notebook.
Massive Capacity
WD's 320 GB 2.5" drives offer huge capacity for space-hungry operating systems with plenty of room left over for photos, music, and video.
Tested for Compatibility
Performs tests on hundreds of systems and a multitude of platforms in the FIT Lab and Mobile Compatibility Lab to give you the confidence that the drives will work in their systems.
In a notebook drive, silence is golden. WD's exclusive WhisperDrive combines state-of-the-art seeking algorithms to yield one of the quietest 2.5" hard drives on the market.
Reliable and Rugged
WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks during shipping and handling and in daily operation. WD's SecurePark parks the recording heads off the disk surface during spin up, spin down, and when the drive is off. This ensures the recording head never touches the disk surface, resulting in improved long-term reliability due to less head wear and improved non-operational shock tolerance.
Low Power Consumption
With technologies like IntelliSeek, which calculates optimum seek speeds to lower power consumption and SecurePark, which reduces power by parking the heads during low power idle mode, this drive delivers 5400 RPM-equivalent power consumption in a 7200 RPM drive.
