A:Answer 1000GB/1TB is absolutely enough for more than a few games. How many games depends on entirely on the games themselves. Your storage will fill up quickly if you have a lot of big name first party games though (Ghost of Yotei is about 90GB, Red Dead Redemption 2 is over 100GB, etc). But games from the PS4 library will be much less. The console has a disk drive.
You can also look up on the PlayStation store and on the back of game discs how much storage a game will take up. Keep in mind that the Operating System (OS) of the PS5 will take up about 125GB, so you will have around 875GB of storage for your games.
