I have not had issues with the (sata) SSD either the nvme is really
slow for me its 6 ties slower doing basic operation like untaring a file..
and im not sure if theres any config needed to make this work.
Both drives were configured using gpt(the system automatically configured
them, but

I missed your first post but I
Thanks
Yes ill try bonnie.. but doing simple write to the disk like untar and I
can see huge differences .. its almost 5-6 times slower writing to a nvme
drive then to a SSD..
Im testing on freebsd for now.. but have no intention of changing my OS..
these drives are really costly so want to

This is surely NVME hardware both motherboard and drive support nvme.
Using ubuntu liveboot disk utility I was able to gt 3.8gb read and write
speed..
/sbin/dmesg |grep nvme
nvme0 at pci3 dev 0 function 0: vendor 8086 product 0953 (rev. 0x01)
nvme0: NVMe 1.0

Yes that’s what it seems but The 5 time slower is when I untar a file.. on
the SSD it take 1min to write
