My understanding is that from the 32bit generation onward that data was loaded from the disk into system ram where the CPU would run everything instead of trying to have the CPU read data directly from the disk which was a lot slower and not really possible. Now the PS5 has the nvme slot where you can plugin an external SSD to increase the amount of storage on the system. I watch Reviewtechusa on youtube and he seems to think that if you buy some cheap SSD that doesn't meet recommended read write speeds that the game will not run properly or something along those lines. So can the CPU load data directly from the disk without having to load it into system ram or does it always have to load it into ram first before the CPU can execute it? This question also applies to the PS4 as well. Thanks in advance for anyone who responds to my post.
