If you’ll recall the leaked prototype of the Xbox One X, there’s a weird mystery port on the back of the device. Many, myself included, surmised that it might be for debugging purposes, and not included on the final retail machine. Others hoped it would be for some sort of external storage expansion. I did not think it would be for this, because I know that it’s not an especially deep port, so it’s unlikely to be able to house an M2 NVMe drive. It looks like it won’t have to.
