WD Scorpio delivers best-in-class performance with low power requirements comparable to much slower notebook drives. In addition, you'll get the quietest 2.5-inch drive on the market with real-time data protection technology to help keep your data safe.

Key Features

Fast and efficient - Spins at 5400 RPM for fast performance but has power specs similar to slower 4200 RPM drives. Low power consumption yields increased reliability.

Quiet - WD's exclusive WhisperDrive™ technology with SoftSeek™ algorithms make this the quietest 2.5-inch hard drive, regardless of spin speed.

Reliable - WD's ShockGuard™ technology protects the drive mechanics and platter surfaces from shocks. WD's DuraStep Ramp™ locks the heads in a secure position away from the disk to provide another layer of protection when the drive is not in use. Utilizing the most technologically advanced material available, the drive can perform a minimum of 600,000 load/unload cycles without contamination - up to twice the performance of its competitors.

Rugged - WD Scorpio's rigid stainless steel top cover withstands more than 5 pounds of pressure - nearly 1.5 times the industry average - without pinching vital internal components.

Ideal For

Portable digital devices of all kinds, including notebook computers, portable external storage, digital audio, GPS systems, and tablet PCs.
