I don't understand the pricing on this drive, on the face of it, it looks seriously overpriced. Although the Black has a marginal speed advantage compared to a 3TB Barracuda, one 4TB Caviar Black costs more than two 3TB Barracudas! I have only seen benchmarks from 3 user samples for the 4TB 2012 Black so I will re-visit this recap over the coming months by which time I should have a better sample size. Additional samples may indicate far better performance than I have seen so far. [Aug '13 HDrivePro]
