It's always good to have a little extra storage on your device, whether that's on a PC, laptop or console. And if you're an avid gamer, you'll know all too well how quickly storage can be used when installing a new game, with some recent AAA titles easily commanding over 90GB per game. With that said, expanding your storage can be quite costly, especially if you're looking to max out your device with 2TB or more.
