Forums - Gaming Discussion - Why the SSD is a big deal for PS5, Series X.

I would say it is the controller. Because even old PCs with slow HDD used that for "cache" as some virtual RAM.

So when SSD is very fast on PS5 it can help the RAM without being an issue for the performance I guess. There is also the coherence unit that will support the fill and removal of data from the RAM and that is on the SSD solution.

Yeah, it feels like the speed they went with is what they found to be necessary for these functions. I believe he said something like that too.
To eliminate loading screens, the new decompression technology to save dev time, not having to repeat assets clogging up space on the Blu-Ray, and to function as RAM for better games.

An analysis from NXGamer makes the hypothetical claim that with the SSD that Sony is using, they could move OS operations onto it and effectively give games like 15.5GB ram usage.

Thoughts?



So basically, we could get Sonic games that run decently :0

That would be really interesting, but it needs to go to CPU/GPU and I don't think there is a direct link to SSD. But perhaps since it is so fast it stay out of the RAM and dump all at once when you press home.

Could be kkkkkk

Actually yes!  

Should be able to make ridiculously fast Sonic games to boot.

Great thread , actually i planned to make one. But afraid being challenged by many smart people.

I feel like it would be more valuable to have this SSD technology to render assets than say 4GB extra RAM.
But I guess for some games, more regular RAM may be better.

They promised us that with 8 core CPUs in consoles would come a better use of multi cores on PC. So I'm not holding my breath for the SSD revolution.



If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.

We could get nauseating fast ludicrously pretty Sonic games both 2D and 3D.

That is a pretty obvious idea, I'm sure Cerny has tested that idea with some games. They tested bc with the top 100 games and I'm pretty sure Cerny thought of adding that to the test suite to see how far they can go with stripping down the in-memory os.

Basically you keep the Kernel and the most used os functions in ram. At around 6G/s, loading a few megabytes of os code at highest priority setting (there must be a reason they have 6 priority levels in their custom controller) is almost unnoticable. My guess is 15 to 15.5GB usable ram is entirely achievable.
