We hope you weren't counting on using the Xbox One's USB ports for external storage from day one; as it turns out, you'll likely have to be patient. Speaking at the PAX Prime expo this weekend, Microsoft's Larry Hryb (aka Major Nelson) mentioned that external drive support wouldn't be available at launch because the Xbox team was "working on other things." It's not certain when the feature will arrive, Hryb says. We've reached out to Microsoft to verify the statement. If it's accurate, though, you'll want to be cautious when filling the Xbox One's built-in 500GB drive with Xbox Game Store downloads.
