The 6TB WD Red is one of the first 6TB consumer drives. Sporting five large 1.2TB platters the Red is targeted at consumers for use in 1-8 bay NAS (Network Attached Storage) devices. The large platters on the 6TB drive enable slightly faster peak read speeds than on the smaller capacity Reds. Comparing performance between the 2TB and 6TB versions shows that the 6TB version is between 10 and 15% faster. At current market prices ($300) the 6TB red isn't a bad value proposition and, considering that the 6TB Red is just a few months old, prices are likely to drop significantly over the coming months. [Oct '14 HDrivePro]

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]
