Western Digital 40GB Scorpio Hard Drive Features
Efficiency Spins at 5400 RPM for fast performance but has power specs similar to slower 4200 RPM drives. Low power consumption yields increased reliability. The drive spins at 5400 RPM, but all other specifications match 4200 RPM drives. The drive requires only as much power as a 4200 RPM drive, runs as cool as a 4200 RPM drive, and therefore delivers optimum reliability.
Quiet WD's exclusive WhisperDrive technology with SoftSeek algorithms make this the quietest 2.5" hard drive, regardless of spin speed.
Reliability 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.
