Key Features
- Top performance for Windows Vista - The WD Caviar SE16 500 GB SATA drive received a 5.9, the highest possible score 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.
- IntelliSeek? - Calculates optimum seek speeds to lower power consumption, noise and vibration.
- Ramp Load - 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.
- Preemptive Wear Leveling (PWL) - The drive arm frequently sweeps across the disk to reduce uneven wear on the drive surface.
Ideal For
Designed for use in the fastest PCs on the market, including high-performance business computers and multimedia or gaming systems. Perfect for Windows Vista.
