Product Features

Fast and efficient - With 5400 RPM spin speed and 12 ms access time, even the most demanding customer will appreciate the performance achieved by WD Scorpio drives.

Quiet - In a notebook drive, silence is golden. Western Digitals exclusive WhisperDrive combines state-of-the-art seeking algorithms to yield one of the quietest 2.5-inch hard drives on the market. Optimizing the way a drive seeks for data also aids significantly in saving power. So now silence with longer battery life is golden.

Reliable and Rugged - Western Digitals ShockGuard technology protects the drive mechanics and platter surfaces from shocks. Western Digitals 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.
