Designed with top-of-the-line notebook computers in mind, this high performance drive delivers the capacity and speed needed to supercharge a notebook PC without compromising battery life or quiet acoustics. Features like these also make this drive an outstanding option for compact desktops, external hard drives and gaming systems.

Desktop-class performance for notebook computers - With 7200 RPM spin speed, and 16 MB cache, 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 500 GB 2.5-inch drives offer huge capacity for space-hungry operating systems like Windows 7, 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 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.

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.

Tested for compatibility - WD performs 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.
