Top performance for Windows Vista - WD Caviar SE16 SATA and EIDE drives are certified for Windows Vista and are top performers on the Windows Vista Experience Index. 16 MB Cache - Bigger cache means faster performance. A massive 16 MB cache combined with advanced acoustic and power-reducing technologies make these ultra-fast drives the perfect solution for the fully loaded PC. Perpendicular Magnetic Recording (PMR) - The latest generation of WD Caviar SE16 drives employs PMR technology to achieve even greater areal density. IntelliSeekTM - Calculates optimum seek speeds to lower power consumption, noise and vibration. SecureParkTM - 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. Less
