1TB Western Digital blue 3.5-inch HDD $59
If you’re on a budget, and don’t mind being a little more scrupulous with your games and content, running with a 1TB HDD for your backup drive isn’t too much of a stretch.
Western Digital is one of the better hard drive brands out there. And the Blue series is primarily intended for reliable desktop use, so this $59 box of joy will serve you well. The WD Blue series also supports SATA 6.0 Gb/s, and together with a relatively decent 7200 RPM rotational speed will deliver performance that will keep access times reasonable.
