Can I use a external disk drive for the disc less xbox one s?

Hi,

No sorry. External blu-ray drives are not supported. Only external hard drives.

If you have a large collection of games on disc you should buy the console with the drive.

Hi There,

You unfortunately can't use a external disc drive, but game codes are getting cheaper and there is the Christmas sale happening right now through Xbox so you can pick up your favourites.

Unfortunately, you can't use an external disc drive on your Xbox

Sadly, no. External disc drives have been used in previous consoles across all brands to support massive game piracy. The disc drive in an Xbox One has special capabilities to verify that discs are genuine and this cannot be safely done with an external
drive. The disc-free console simply cannot be used to play disc games. Fortunately, all titles are available for digital download so it can play everything you'd want it to play. But if you have an existing collection of Xbox discs, you should definitely buy
the console with a disc drive.

I don't think so. Otherwise, Microsoft would sell this external disc drive as an add-on but they don't.
