Sweeney says that Sony’s storage architecture is far ahead of “the best SSD solution you can buy on PC today. And so it’s really exciting to be seeing the console market push forward the high-end PC market in this way.”
“[The PS5] puts a vast amount of flash memory very, very close to the processor,” says Sweeney. “So much that it really fundamentally changes the trade-offs that games can make and stream in. And that’s absolutely critical to this kind of demo,” Sweeney explained.
“This is not just a whole lot of polygons and memory. It’s also a lot of polygons being loaded every frame as you walk around through the environment and this sort of detail you don’t see in the world would absolutely not be possible at any scale without these breakthroughs that Sony’s made.”

PS5 SSD Is 'Far Ahead' of High-End PCs, Epic Games CEO Says - IGN
The PlayStation 5 breakthroughs on SSD and storage are ahead of any PC alternatives.
Thanks

Edit:
"A number of different components are required to render this level of detail, right?" offers Sweeney. "One is the GPU performance and GPU architecture to draw an incredible amount of geometry that you're talking about - a very large number of teraflops being required for this. The other is the ability to load and stream it efficiently. One of the big efforts that's been done and is ongoing in Unreal Engine 5 now is optimising for next generation storage to make loading faster by multiples of current performance. Not just a little bit faster but a lot faster, so that you can bring in this geometry and display it, despite it not all fitting and memory, you know, taking advantage of next generation SSD architectures and everything else... Sony is pioneering here with the PlayStation 5 architecture. It's got a God-tier storage system which is pretty far ahead of PCs, [but on] a high-end PC with an SSD and especially with NVMe, you get awesome performance too."

This is next-gen: see Unreal Engine 5 running on PlayStation 5
We've seen the specs, we've heard the pitches - but what we haven't experienced is any demonstration of a genuine next-…
