Yeah. I've got a 500GB SSD hooked up to my Xbox One and it works flawlessly. It reduces load times quite a bit in certain games too.Canceled my 2TB pre-order and ordered the 500GB Halo bundle. I can wait the extra couple of weeks, and Halo 5 was one game I was planning on picking up anyway. The ability to add external USB storage renders the extra space irrelevant (I think).
