Besides that he's right.
Windows load time.
Tomb raider:
SSD M.2 - Samsung 970 EVO 500 GB (3400/2300 )
SSD SATA3 - Samsung 860 Evo-Series 500GB HDD ( 550/520 )
Western Digital Blue 7200rpm 1TB ( faster then PS4 )
Reducing 1 minute towards 1 second needs 60x the performance. Even if after that u get a SSD that's 3000 times faster. U will only gain 1 second of load speed advantage over that 60x. Which makes it completely pointless.
This makes 5400rpm > sata 3 ssd huge while sata 3 ssd > nvme not so much.
This is the issue that SSD's have and why i said earlier on even nvme ssd's are overkill for those consoles. Xbox series x kinda stole the thunder from sony by announcing a 2gb's ssd that no matter what sony does isn't going to move away from much noticeable as they are limited by pci-e 4.0 which is 5gb's.
Any exotic hardware design they are planning to push out to capitalize on that SSD performance in exotic ways will be ignored entirely if the rest of the market won't join it. Much like blu-ray in the PS3 area. So it will just be for there first party efforts which frankly don't even remotely need it at all. Just a waste of space.
