Here's Proof That External Storage Support is Coming to Xbox One
Posted by Anthony Bacchus
Anticipated feature possibly coming in next system update
We've heard it from Microsoft's mouth that external storage support for Xbox One is coming in a future system update. Thanks to a post from Reddit user XboxOneDev, we may have confirmation that the highly-requested feature could be ready to go real soon.
In the picture posted above, we can see a notification message that says "External Drive Ready" on the bottom as well as significantly more storage space available on the users' Xbox One. The Reddit poster (a confirmed Xbox One developer) also teased "adding more hype on the list of things to come."
Monthly patches have been released regularly for Xbox One. We already know the new additions incoming in the new May system update, so it is possible that Microsoft could be preparing external support for the June or July update.
