WD Scorpio Blue 640GB 2.5" Notebook Hard Drive, 8MB Cache, SATA 3Gb/s, 5400 RPM Speed, Single Pack

The WD Scorpio Blue 640GB Hard Drive offers a high-performance, low power consumption and cool operation that is perfect for notebooks and other portable devices. WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks.

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.
