A:Answerthe first question i must ask is: is it a ps4 or a ps4 pro? the regular ps4 has 2 usb port on the front only one of them can run a portable external hd if i remember right it will be the one that is closer to the side of the machine. now the pro has a external hd (usb) port on the back it was put there for just such a device (to keep the front neat) or you can use the front port (the same one as the non pro). i hope this helps
A:AnswerNo, go to Sony.com for more information about how the ps5 holds data and games. Externals do not work on the PS5 the way they did on the PlayStation 4
A:AnswerYes it will free up a lot of space and has plenty of room on it. I moved over all of my games and lowered my PS 4 pro space to less than a quarter of space being used
