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

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 nvme0: for admin queue interrupting

I have a Supermicro nmve supported hardware X10DRL-CT with a SSD sasa drive and an intel nvme pcie drive.. both drives are 2tb and I have used gpt with the latest 7.99 daily build from today Using netbsd using dd if=/dev/device of=/dev/null bs=16k Sata SSD : 33967620096 bytes transferred in
