Right, and whilst 3.0 switches are semi-affordable, 4.0 or 5.0 costs significantly more, though how much that matters obviously depends on your workload.

- magicalhippo 2y agoTrue. I think a switch which could do for example PCIe 5.0 on the host side and 3.0 on the device side would be sufficient for many cases, as one lane of 5.0 can serve all four lanes of a 3.0 NMVe. But I realize we probably won't see that. Perhaps it will be realized with higher PCIe versions, given how tight signalling margins will get. But the big guys have money to throw at this so yeah...
