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 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.
And when you buy from WD, the world's leading hard drive supplier by volume, you gain comfort in knowing that the drive has been extensively tested for reliability and compatibility and will be supported by world-class technical support.

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.
