Massive capacity
Storage capacity for 2.5-inch form factor drives with standard 9.5 mm height has arrived at a realm once thought to be impossible - up to 1 TB* - giving you all the capacity you need to keep your photos, music and files right there on your notebook.
Quiet
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. These
algorithms also optimize the way a drive seeks for data, which significantly improves power consumption. So now silence (and longer battery life) is golden.
Reliable
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 nonoperational shock tolerance.
Rugged
WD's ShockGuard™ technology protects the drive mechanics and platter surfaces from shocks.
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 our customers confidence that our drives will work in their systems.
A
dvanced Format (AF)
Technology being adopted by WD and other drive manufacturers to increase media format efficiencies, thus enabling larger drive capacities. (PVT models only)
