    "I ran out of internal storage fast and had to upgrade. This is the largest size hard drive able to use on the Xbox One X. ...I've owned many different external hard drives over the years, this is by far the largest (in storage size) I've had. Western Digital makes good-quality drives (never had one fail yet), some are faster than others, but this one seems fairly fast and only has a bit of lag accessing it if you haven't accessed it in a while.
