Will there be bigger external storage options for the new Xbox Series?

You can still use external HDD for your Xbox/Xbox 360/Xbox One games but you can't play Series X/S games from them,

Series X/S games can only be played from the internal or external storage card,

with game file size's getting bigger, that 1Tb internal NVMe SSD is going fill up quick.

Hi,

Yes you can use it. You can use any external storage that the Xbox One supported on the Series X and S. However, external storage can only be used to play Xbox One games and BC Xbox 360 and original Xbox games.

Series X and S titles need to be run either from the internal SSD or the optional expansion card.

you need to get a bigger usb or use a external storage

Hi,

If your game is now a Series X optimised title, it can no longer be played off an external hard drive. It must be moved to either the internal storage or an optional expansion card.

External USB hard drives are too slow to play Series X optimised games. None Series X games will still run from your external drive. The internal storage in the Series X is a fast NVME SSD. These drives are several times faster than mechanical hard drives.

Your only solution is delete games/apps or external hard drive with bigger storage
