It happens to all of us at some point. We constantly run short of hard drive space, no matter how incredibly cavernous you thought your current drive was when you bought it. Did you really expect Dragon Age: Origins and Borderlands to soak up almost thirty gigabytes between them? Didn’t think so. You either shove Office 2007 and Photoshop CS aside to make some room for your latest losslessly-ripped music and RAW photos, or grab a drive that offers up more capacity, say up to 2TB–such as the ones we’re going to be evaluating here.
You know the contenders. These aren’t solid state drives full of a speedy but thimble-sized flash memory chips–these are large, succulent drives with platters humming at 7200rpm and they’re made by Western Digital.
