NOVA Label Factory Deluxe 4.0 - Windows Massive capacity - Storage capacity for 2.5-inch form factor drives has arrived at a realm once thought to be impossible - up to 1 TB for mobile storage. Whether they are in an external drive or a notebook computer, WD Scorpio Blue SATA drives continue to offer the highest capacity for space-hungry operating systems with plenty of room left over for photos, music, and video. 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. Fast and efficient - Ultra-fast 3 Gb/s SATA interface speed yields performance fit for demanding mobile applications. Advanced Format Technology (AF) - Technology being adopted by WD and other drive manufacturers as one of multiple ways to continue growing hard drive capacities. AF is a more efficient media format that enables increased areal densities. (PVT models only)
