Designed specifically for the Xbox One X, One S, One, and 360, the Seagate 2TB Game Drive can store up to 50 games or more, depending on the file sizes of the games, which is typically 35GB to 50GB per game. With this portable storage drive, you can take your favorite games with you wherever you go and play them with your own Xbox Live login. It's fully bus powered, so no external power sources are required, and works straight out of the box; however, formatting may be required. When connected to your Xbox's USB 3.0 port using the included 18" micro-USB 3.0 to USB Type-A cable, it delivers data transfer speeds of up to 140 MB/s and is also compatible with USB 2.0.
