Still practically highway robbery. Toshiba retail-boxed 3TB 7200RPM HDDs with 3-year warranty drop down to $100 every few weeks / months. Probably still cheaper to purchase one of those, and a 2-year extended warranty at Newegg, than pay for a Black.
WD is holding desktop drive purchasers hostage, by only offering their cheaper 7200RPM "Blue" drives in up to 1TB capacities.
If you need 2/3/4TB, it's either a horribly-overpriced Black, or a 5400RPM Green or Red. Sure, they came out with Red Pro, some of them are high-capacity and 7200RPM, but they are priced like Black drives.
Edit: I guess what I'm trying say, and trying hard not to directly thread-crap, because if that's the lowest price available for that drive, then it is indeed a deal, but I'm more of the school of thought of buying more cheaper drives, for redundancy, rather than rely on a single high-priced drive that happens to have a longer warranty. That's still no guarantee that it won't go south on you. Backups!
