btw, unless you get like the nyko bank, I don't think you can fit anything but a 2TB or less with an hdd, since it has to be 9.5mm. you can with a ssd, but I'd advise you put your games on an external hdd with extended storage, since it can be used on any other ps4, in case the hdd or system fails. hen will repopulate the games. also, I bought a 5TB, because it at least was the largest unpowered hdd on the market. it's a wd black. you don't need a y cable like the wii u either for both the ps4 or the ps5.
