2.5-inch SATA Hard Drives 320 GB, 3 Gb/s, 8 MB Cache, 5400 RPM
WD Scorpio delivers best-in-class performance with low power consumption and cool operation. In addition, you'll get one of the quietest 2.5-inch drives on the market with real-time data protection technology to help keep your data safe.
Key FeaturesMassive capacity - Whether they are in an external drive or a notebook computer, WD’s 320 GB 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, even the most demanding customer will appreciate the performance achieved by WD Scorpio drives.
Quiet - In a notebook drive, silence is golden. WD’s 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.
Ideal For
Portable digital devices of all kinds, including notebook computers, external storage, and digital media players.
