I wouldn't want it unless I wanted storage. For gaming however I'd use a small SSD Hyperdrive5 which only holds 64GIG **BUT** the speed of which blows this and all hard drives out of the water. For instance; loading windows xp on HyperDrive5 takes 4 seconds to load up. In the world of computers sometimes the best comes at a sacrifice. I'll take speed over how much data I can store on it. I'll just get a larger drive to compliment what it doesn't provide in storage.
I don't think comparing a $450 device that still requires a lot of money in ram on top of the original price is a good comparison to the 2tb Caviar black lol
