A:Answer The storage of the PS4 is mostly for gaming. The average game is around 40-60 gigabytes, plus more if you download extra content for a game. The consoles RAM, is memory that allows the console to do many things at once. You can save money by getting a console with the lowest memory, which would maybe be 500gbs for a PS4, if you would use it for streaming video. But if you will use it to download games and watch movies both, get a 1TB model, so you don't run out of space quickly. Hope I helped!
