M.2 compatibility

Wing-Man · 4 Mar 2022 at 13:52

Just a quick one, I just picked up a 2tb ssd and want to run that at full speed in my main m.2 socket. My second m.2 is run off chipset at gen2 speeds will my gen3 work in that socket? I’m assuming there backwards compatible.

old drive is WF blue sn550, second m.2 is wired to pcie 2.0 x4

It will work fine, PCIe is completely backward and forward compatible. What motherboard do you have?

As long as both slots are NVme and not m2 sata it will be fine. I think pcie gen 2 at 4x tops out at about 2GB/s, so technically slightly slower than your old drive, but I doubt you'd notice any difference outside of benchmarks.

MSI B450m Mortar MAX, without looking again im 99% the second socking runs of the chipset so is PCIe but only 2.0

Yeah, both slots can handle NVme drives, so it will work no problem, it will just be ever so slightly slower. I have the same drive, and it benches at about 2200MB read, so it would be bottlenecked in a 2.0 slot, but you aren't going to notice the difference in actual use.

Yer that’s fine tbf when I went from a sata ssd to the nvme I noticed no difference. I only got the new one to get rid of my 2tb WD green as it very old and started clicking

thanks for the help though, would there be any boot problems if I switch it before cloning the boot info over

Should be fine, I don't think the bootloader cares which slot it's in.
