With available SATA or EIDE interfaces WD Scorpio Blue drives offer high-performance low power consumption and cool operation perfect for notebooks and other portable devices. Pick the drive that suits your needs with the confidence in knowing that all WD Scorpio Blue drives are built to the highest standards of quality and reliability. To make drive selection simple we've gathered all our popular 5400 RPM WD Scorpio drives under one umbrella we call WD Scorpio Blue. Built to Western Digital's awarding winning quality standards these drives are available in a full range of performance features. Whether they are in an external drive or a notebook computer WD Scorpio Blue SATA drives are available in capacities up to 500 GB and offer the most available capacity for space-hungry operating systems like Window Vista with plenty of room left over for photos music and video. 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. 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.
