Question Do PCIe 4.0 SSDs work on Z370 motherboards?

[Shujee]

I have a somewhat old Z370 motherboard (AsRock Z370 Killer SLI/AC) that supports PCIe 3.0 and I'm currently using Samsung 970 Evo Plus 512GB on it as my boot drive. Can I upgrade to 1TB 990 Pro, which is a PCIe 4.0 disk? Will it perform any better than PCIe 3.0 SSDs?

Also can this have any issue with my GC (MSI 1060 Gaming X), like number of PCIe lanes or something?

No it will be helded back by the motherboard interface. Just get a gen 3 x4 nvme instead.

A PCIe 4.0 disk will perform the same.

It will just run at pcie 3 speed.

Perf wise you would be hard pressed to tell the diff between pcie 3 vs pcie 4.
