Librem 15 v3 M.2 interface SATA or NVMe performance?

[scaled]

I don’t sure about NVME speeds, but i only found this thread:

Librem 15v3 + Qubes 4.0 - the good, the bad and the ugly

I’ve tested Samsung Evo 960 NVMe. There are some performance issues. Sequential write speed is limited to one third of the expected speed. Read speed seems to be ok. So, actually with the coreboot issue of SATA SSDs it is not a great fun.

@kakaroto

if you’re asking why your NVMe is slower on the librem than on some other machine : no idea, It might be a hardware configuration (NVMe is PCI-express, so maybe the x2 or x4 or whatever is what affects), it might be a kernel driver or a windows vs linux (your other test was on windows?) or anything like that. I haven’t seen anything about nvme in coreboot config, but maybe I can look and find something, can you give me a summary of the issue, I got lost with all the numbers you posted before?

Please, wait for another replies. It can be just one bad case, because we don’t saw feedback from users, which NVME’s works fine.
