External Drive Optimization on Xbox Series X

First if it's an xbox series x optimized game moving it to an external drive won't work

Only bc titles that arent patched can

You can look at your library to see which ones are optimized or patched for the fps booster

Only the external nvme for series x Seagate cards work with optimized games

There's nothing wrong with it, but regular external drives are not fast enough to handle Series S/X optimized games.

If he has a Series S/X and is trying to play a Series S/X optimized game, it will only run on the internal drive or on an expansion card made for the Series S/X. It won't run on a regular external hard drive or SSD.

Yes you can. The expansion card is for Series S/X optimized games. So you should be able to run any game from them as opposed to regular external hard drives which cannot run Series S/X optimized games.

It depends on what you use as external storage. If you get a regular hard drive or SSD, then any Series S/X optimized games will still need to be moved to the internal storage to play them (Older games can be stored and played from the external drive). If you want to store and play Series S/X optimized games on external storage, you would need on of the expansion cards that were created for the console.
