The simplest solution is an external storage device. The Seagate Game Drive for Xbox One and Xbox 360 will be ready for data transfer and storage in a matter of seconds, just plug and play.
"Free up space on your console's internal drive while consolidating 50+ Xbox One games into a single location," Seagate's product page reads.
Game Drive goes on sale later this month from Gamespot, Amazon and the other usual suspects, with a MSRP of $109.99 USD.
