Now that the proverbial cat is out of the bag on Western Digital's 2TB Caviar Green HDD, hardware fanatics have had a chance to take the 3.5-inch drive for a spin. While its performance leaves something to be desired -- transferring files took longer than the 1TB Caviar Black or 1.5TB Seagate Barracuda -- instead we've got low heat and noise. Of course, the biggest boon is a ginormous storage capacity for just three Benjamins, the same price as some 128GB SSDs. Solid state be damned, rotating disks aren't going away anytime soon.
