A:AnswerIt's just a USB drive, although it has a very distinct color scheme. It should work anywhere a USB drive is needed. Incredible value for the price.
A:AnswerI use mine on my Xbox One. When I hooked it up it needed to format to that system. I believe if you hook it to a PC it will either be formatted for that or will format for it once plugged in, but I can't say for sure.
A:AnswerYes any Xbox model this will work just fine for transfers of data or as extra storage but I don't think it will work as far as playing games downloaded to it off the series S/X I used it to go from Xbox one original to a Xbox series X but I hope this helps.
