Xbox One's 500 GB hard drive reportedly maxes out around 362 GB used, meaning more than 25 per cent of the console's storage space is used up before any game content files are added.
IGN reports that owners have access to 362-365 GB of space, despite getting no clarification from the hardware itself on what the actual limit is and how much space is currently in use.
The numbers aren't exact as the outlet went about testing the hard drive's space the old fashioned way, and ended up having nothing smaller than a 3 GB title when the 362 GB mark had already been reached.
Microsoft has yet to issue any response or comment on the claim thus far.
