PC isn't really being underestimated here, because it does not have the SSDs ready to go toe-to-toe with the one in the PS5. On top of that, it's more a matter of I/O than even SSD speed. A lot of what is being said is not just fluff to bat chests. These changes are real.
The best example will be in something like a Spider-Man game. See those benches repeated in the game (where they are stored in a folder with that many files in it)? Next gen, it will be one bench stored and the many, many others instanced around the city (keeping folder sizes down and access to the data much faster). That is what is going to make these particular advances in the new machines so important.
I am not saying the changes aren't real. I am sure games will see a huge improvements in game design and etc when moving from hard drives to SSDs. What I am suggesting is that majority of the 3rd party games will not require Ps5's SSD and will work just fine with Series X and a lot of PC's Nvme SSDs, specially with things like DirectStorage API and the rumoured Tensor Memory Compression from Nvidia. Because if it did need PS5's SSDs, then they wouldn't get any sales from Series X or PC which is silly at best... First party games, yea, they can make use of the SSD no doubt...
It isn't a matter of a requirement for function, but for real change, yes, these SSDs will be necessary. People don't really understand — developers have been asking for this for more than a generation. No one said that only the PS5's SSD can take advantage of the engine (or any engine, for that matter). That would obviously be a misinformed suggestion given what is coming to PC in the next few years. Rather that it will be better at doing so given its advantage.
Unless everyone wants just another generation, for more things on screen, better physics, AI, efficient use of raytracing and fuller worlds...
.....then said SSDs will be essential to that move forward.
