Desktop-class performance for notebook computers
With 7200 RPM spin speed,16 MB cache, and capacities up to 750 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.
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
WD’s 750 GB 2.5-inch drives offer huge capacity for space-hungry operating systems 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
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.
Advanced Format (AF)
Technology being adopted by WD and other drive manufacturers as one of multiple ways to continue growing hard drive capacities. AF is a more efficient media format that enables increased areal densities. (BPKT models only).
In a notebook drive, silence is golden. WD’s exclusive WhisperDrive™ combines state-ofthe-art seeking algorithms to yield one of the quietest 2.5-inch hard drives on the market.
