The internal hard drives segment has been totally dominated by the fastest hard drive there is - the WD Velociraptor. It's something I've tested a long time back and it's one drive that even challenges the highly anticipated solid state drives. I received the Caviar Black from WD but it doesn't match the performance of the Velociraptor. The WD Velociraptor goes on to win the Best Performance award of this segment. Both the 150 GB and 300 GB versions are equally fast.
Would love to here from you...
