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.

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.
