Many people were upset when Microsoft announced that the Xbox One wouldn’t support external hard drives. For people who own several games, the Xbox One’s 500GB internal hard drive simply isn’t big enough. Fortunately, a modder has proven that the Xbox One can boot from a non-stock hard drive and is working on a way to make it fully compatible.
Despite the lack of support to swap in different hard drives (especially ones of a larger capacity) in the Xbox One, this guy says he’s gotten the two pieces of hardware to cooperate. Not only that, the console runs faster with a non-stock hard drive installed.
