similar issues when using NVMe drives on Linux. In contrast, when I tested the

Could you provide any methods to optimize the performance of my NVMe drive on Linux?

To help with the second question, see

I used Windows on a thumb drive to update the firmware of several
Samsung SSDs used in my Linux machines.

For one of the drives, I seem to recall the program said it could not
find a Samsung SSD though it was installed. I assumed it was a
counterfeit drive from Amazon.

(I use the same WIndows thumb drive to update BIOS and UEFI, too).

I suggest you start by

checking the kernel version, ubuntu is kinda like debian, it may be an 
"old" one (relatively) especially LTS ... .


big chances that updating your kernel will be more than sufficient .
