Western Digital has introduced a new Caviar Black line of hard drives that is available in both 750GB and 1TB storage capacities. The new drives have twice the normal cache size of typical drives with 32MB of high-performance cache memory. The Black edition drives also feature dual electronics architecture processors for twice the processing power.
The motor shaft on the drives is secured at both ends to reduce vibration and the technology is dubbed StableTrac. Western Digital also uses NoTouch ramp technology that prevents the recording head from touching the media for reduced wear and longer operational life. The Caviar Black line uses SATA 3.0 interface. The buffer to disk transfer rate is 145MB/s max.
