Expansion card versus external USB storage
An external USB drive is not a substitute for the expansion card in every use case. SanDisk’s Xbox Series X|S external-drive guidance says Series X|S-optimized games cannot be played from external USB storage. The available guidance does not establish all transfer, storage, or backward-compatibility rules, so check Xbox’s current support information for the specific game or storage-management choice.
