Again, my understanding is that, yes, it's a pretty fast SSD, but what makes it shine is how the system interfaces with it. 12 channel memory controller with 6 priority queues (vs 2 on a regular PC NVME) make it very low latency when you compare it to a typical storage setup.

Do you not see the potential issue if you drop in a commodity PC SSD?

There are fundamental design choices in Sony's I/O layout that may make it incompatible with commodity PC drives.
Microsoft also made a similar decision, hence it's propriety "memory card" approach.

I doubt it's as low latency as Optane or an SLC SSD.

That is the reason Cerny said a regular SSD would probably need 7Gb/s transfer rate to compensate for the lack of 6 priority levels and that they will need to test different SSDs on the market to verify if they will be acceptable. I would expect something along 2021-2022 having some SSDs that could be installed and probably we will have some partnership and official SDD upgrades.
