Sony big shots are saying it. A heavily customized SSD with higher bandwidths you can see on PC. They are straight up lying then.

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.

aren't you being a bit disingenuous yourself here?

Unless I missed a more recent comment, Cerny said it was better than anything in current PCs when PCI-E 4.0 wasn't released. And an Epyc CPU is not something for "PCs" (_personal_ computers), it's server hardware. The kind of raids you describe are extremely unlikely to be used for personal/private use.
