After the IDE, came SATA 1.0 or SATA 1.5 Gb/s, then SATA 2.0 or 3 Gb/s. And as if that wasn't enough, now there is the latest SATA 3.0 or SATA 6 Gb/s, yet again raising the bar of data transfer limits of the interface. The world's first hard drive with this high speed interface is the Seagate Barracuda XT 2 TB desktop hard drive (ST32000641AS). Known as the XT or extra performance, this drive boasts of superior performance with the platters spinning at an RPM of 7,200. We have this 4-platter drive with us and we will try to find out if the new faster interface does indeed perform as good as it is on paper.
