SATA 6 Gb/s interface - Twice the interface speed with backwards compatibility to legacy SATA standards.
Dual processor - Twice the processing power to maximize performance.
Dynamic Cache - WD's dynamic caching algorithm improves performance in real time by optimizing cache allocation between reads and writes. For example, if there's an overwhelming percentage of read traffic as opposed to write traffic, the drive automatically allocates more cache for read data, which reduces congestion and improves overall drive performance.
NoTouch ramp load technology - The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
StableTrac - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations which enables consistently higher performance.
Desktop / Consumer RAID environments - WD Caviar Black Hard Drives are tested and recommended for use in consumer-type RAID applications. (RAID-0 / RAID-1)*
