lol again with misinformation. Yeah, if you only have Call of Duty downloaded, you only got space for 5-6 games. At this moment I got downloaded Spiderman: Miles Morales, Fifa 21 PS4, Fifa 21 PS5, Yakuza Kiwami 2, Elden Ring, Shadow of the Colossus, Arkham City, Arkham Knight, Persona Strikers, Ratchet and Clank (the PS4 version), Telltale Batman, Trackmania, Rocket League, Fall Guys, Mirror's Edge Catalyst and The Last of Us. And still got another 100 GB space if I want to download something.
My friend bought an extra SSD disk for 60 bucks, another 480 GB of space and it works great. Seeing how cheap a PS5 digital is, 825 GB SSD disk (667 GB for games) is actually good enough.
