Key FeaturesDesktop-class performance for notebook computers - With 7200 RPM spin speed, 16 MB cache, and capacities 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-inch drives offer huge capacity for space-hungry operating systems like Windows Vista™, with plenty of room left over for photos, music, and video.
Low power consumption - With technologies like IntelliSeek™, which calculates optimum seek speeds to lower power consumption [View demo] and SecurePark™, which reduces power by parking the heads during low power idle mode [View demo], this drive delivers 5400 RPM-equivalent power consumption in a 7200 RPM drive.
Quiet - 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-inch hard drives on the market.
Reliable and rugged
Tested for compatibility
- We perform tests on hundreds of systems and a multitude of platforms in our FIT Lab™ and Mobile Compatibility Lab to give WD customers confidence that our drives will work in their systems.
