Building the GEARBOX: Take on Borderlands 2 With the Ultimate $2500 Gaming PC
The Platter: Western Digital Caviar Black 1TB Hard Disk Drive
These days a gamer doesn't buy a hard drive for raw speed; even the fastest are blown away by solid state drives. Assuming you can't fit all those games, videos, and documents on a 256GB SSD, you'll still need some platter-based storage to hold it.
There's a chance you may even run some of those less demanding games from the hard drive, where Western Digital's Caviar Black is a solid performer. Its best feature, however, is the five year warranty.
