A:Answer Hello Solomon,
The Seagate One Touch meets the requirements to be used on XBox One S (at least 256GB and support USB 3.0), however our labs haven't tested this drive on XBox One S, that's why we cannot assure that it's compatible with that console.
Seagate has a line of specific products for the XBox, that works on both Series X/S: the Game Drive for XBox.
Please check on this product's support site for detailed infos:
