NVMe really is nice and much faster than SATA. I tried one
(Samsung 970 PRO 512GB M.2) in an HP ML110 Gen7 server with a
4-lane PCIe adapter card recently.
I couldn't boot from NVMe, even with a BIOS update from this year,
so the boot partition had to go on a spinning disk and everything else on
the NVMe. I could have used a SATA SSD to boot from of course, but didn't
have a spare to hand. Read and write speeds were limited by the PCIe v2
on the motherboard.
