The PS4 already has a huge hard drive, but in the age of digital downloads and day one updates, a time will soon come when you're having to take time away from playing to manage your storage. An external hard drive negates this problem, allowing you to download to your heart's content. The Nyko Data Bank is a two terabyte drive that's fairly cheap and worth the purchase. Why not upgrade the HDD yourself? it's rather simple to do when using our PS4 HDD upgrade guide.
