Over the years the industry has increased bus bandwidth from PATA through SATA 1.5 Gb/s and 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 and 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 and motherboards coming to the market.

Why should I buy a SATA 6 Gb/s hard drive from WD?
Buying a SATA 6 Gb/s drive now is a great way to make sure your hard drive will be compatible with next generation motherboards and chipsets.

Will SATA 6 Gb/s drives work with older systems?
Yes, the SATA 6 Gb/s interface uses the same connector as SATA 3 Gb/s and is compatible with Microsoft Windows 7 / Vista / XP / 2000 and Mac OS X.
