I was referring to the "more raw bandwidth than anything available for PC".
The NAND in fast NVMe SSDs costs quite a bit more than that in a bottom of the barrel 20k IOPS QLC SSD.
Of course that depends on how much marketing is in that "faster".
If they just go for a large array of QLC, pretend that PCIe card SSDs don't exist and build something that does >4 GB/s sequential and not much else they can technically call it "faster*" than any SSD available for PCs.

Of course if you want to play that game you can limit it to SATA SSDs instead of PCIe 3.0 x4 and call anything >600 MB/s "faster than anything available for PCs".
Or just define "raw bandwidth" as the theoretical speed of the interface.
But that's not actually useful. I don't think game developers would be happy if Sony told them "You asked for an SSD so we got you an SSD. It doesn't do anything you'd expect an SSD to do apart from higher sequential read speeds because we went with the absolute cheapest NAND and implementation we could find, but technically it's an SSD".
