To make drive selection simple, weve gathered all our popular 5400 RPM
WD Scorpio drives under one umbrella we call WD Scorpio Blue. Built to
Western Digitals awarding winning quality standards, these drives are
available in a full range of performance features.
Key FeaturesMassive capacity
- Whether they are in an external drive or a notebook computer, 320 GB
WD Scorpio Blue 2.5-inch drives offer the most available capacity for
space-hungry operating systems like Windows Vista, plus plenty of room
left over for photos, music, and video.
Fast and Efficient - With 5400 RPM spin speed and 12
ms access time and up to 3 Gb/s SATA interface speed, even the most
demanding customer will appreciate the performance achieved by WD
Scorpio Blue drives.
Quiet - In a notebook drive,
silence is golden. WDs exclusive WhisperDrive combines
state-of-the-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 and Rugged - 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.
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.
