The WD black 2tb drive is a great choice. I have never had a Western Digital hdd fail on me other than the one time I dropped one of them while it was hooked up externally, and even though the hard drive was a couple years out of warranty they replaced it no questions asked. I have three of the 2tb blacks in my pc as a raid setup right now, and I would love to one or two more for redundancy so in case one fails I won't lose everything.
Great performance, great customer service, great storage capacity, this should be a guaranteed buy for everyone who likes computers and is a data hoarder like myself.
The Western Digital Black, which is faster than anything bar the Samsung Spinpoint F3 (not in production), is much better than anything Seagate produces in the price range.
