No. Because it doesn't work like that.
Games benefit from SSD's on PC. - What has given you the conclusion it doesn't? It's just not as pronounced as this "demo" which is DESIGNED to showcase the differences in the most extreme form possible to try and sell consumers on an idea...
It's not about cool or not it's about software and games application that used and maximize the utilization of SSD and build based on that tech. Non of games that been made are made on SSD in mind.
I have been use SSD as well on PC for quiet long and until these days all games is just load on normal loading screen , what make difference is just using ssd is just more faster .
What we have in the video is they get rid the loading screen and moment. All games from PS5 will be made with this in mind. Thanks to console that push this old tech to become mainstream.
