How would you feel if the PS5 dev kit design was actually the PS5 design?

Yes they are certainly being disingenuous.
In saying that, they are trying to amp-up/promote their console, so there is always dubious claims everytime we enter a new console generation... The frustrating part is that everyone tends to take it as gospel and thus believe it.

PCI-E 4.0 NVMe drives will theoretically top out at around 8GB/s of sequential reads, which is likely what the Playstation 5 will have, taking advantage of AMD's latest technology. - That is stupidly fast whichever way you cut the cake considering most SSD setups today top out at around 4GB/s thanks to PCI-E 3.0 bandwidth limitations.

But the PC can do PCI-E 4.0 x16, and it can do RAID. - Epyc comes with 128x PCI-E 4.0 lanes, which is a theoretical max of 256GB/s of aggregate PCI-E bandwidth available for an SSD setup. - Which is simply an impossible number for a console to cost effectively have for next-gen.

PCI-E 5.0 will likely be available in 2022, Intel will support it with LGA 4677 sockets... And that could theoretically take it to 512GB/s or half a Terabyte per second.
PCI-E 6.0 is being ratified right now with system implementations after that, which will likely double things again.

I thought it was that it would have the fastest SSD, compared to a PC equivalent in price to the PS5. So how fast is the SSD in a $500 PC generally? The PS5 will be faster than that, but won't make it the fastest SSD on the market by late 2020. It may however be faster than anticipated, due to it's customization and integration into the console.

Sony made no mention of price.

But a Ryzen 3000 chip on x570 has 24x PCI-E 4.0 lanes... So you could theoretically do 48GB/s. - But a chunk of those lanes will be for the GPU if you have a discreet card so around 32GB/s is the more realistic number... Which is still insanely fast and much faster than a PCI-E 4.0 NVMe drive.

At the end of the day, there is no "special customization". - Sony will be limited by the PCI-E Specification, SSD (Likely Phison) controller and AMD's chipset/IO  technology.
