Re: Can you not...
The internal drives on the Xbox One and PS4 are SATA II, plugging an external USB 3.0 drive into one of the ports on the Xbox One enables a faster transfer rate, as long as the drive itself spins at 7200rpm, the PS4 does not currently allow external storage. If you have an Xbox One and all your games installed on the external drive, you can plug the drive into any Xbox console and with your login details play the games, as long as a network connection is available to check software keys/certificates.
The upcoming PS4 Pro supports SATA on the internal drive so you can plug in any drive you like, as long as it physically fits.
Xbox internal drives have a specific MS format meaning drives cannot be as easily swapped out and you would break the warranty seal getting to the drive anyway.
