This 7200 RPM speedster is at the top of its class when it comes to performance & reliability benchmarks.WD is leading the way with a full lineup of SATA 6 Gb/s drives. Over the years the industry has increased bus bandwidth from PATA through SATA 1.5 Gb/s & SATA 3 Gb/s to keep up with the demand for higher transfer rates. The next evolution of bus bandwidth has now been achieved with the introduction of SATA 6 Gb/s, (SATA 3.0). We’ve added a SATA 6 Gb/s interface to our award-winning WD Caviar Blue & WD Caviar Black desktop hard drives in capacities from 250 GB to 2 TB. This transition to a SATA 6 Gb/s interface aligns with the introduction of SATA 6 Gb/s-supporting chip sets & motherboards coming to the market.
