Can X1 have an external HDD like PS4?

Wondering because I hear PS4 owners saying that games take up a lot of memory, along with DLC and all that, it sounds like it can add up.

In future, MS plans to add the functionality of connecting external storage to the Xbone. In the meantime, you'll just have to manage your storage space. I'm still greatly looking forward to this Friday!

MS will enable USB storage, with 'NAS' support to follow further 'down the road' : )
