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 .

Hello,
I am experiencing an abnormal performance issue with my Samsung SSD 970
EVO Plus 1TB (2B2QEXM7) on my Ubuntu 24.04 LTS system. My setup includes
a 12th Gen Intel Core i7-12700 x 20 processor, and the SSD is connected
to an M.2 M-key, type-2280 slot (PCIe Gen.3 x4 interface) that supports
NVMe on the motherboard.
Specifically, I have noticed a significantly low write speed of around
700MB/s on my Ubuntu system. After some research, it appears that many
users face similar issues when using NVMe drives on Linux. In contrast,
when I tested the same SSD on the same motherboard using a portable
Windows OS, the write speed was approximately 3GB/s.
Could you provide any methods to optimize the performance of my NVMe
drive on Linux? Additionally, how can I update the NVMe driver on Linux
using "nvme-cli"? Any advice or recommendations you have to address this
issue would be greatly appreciated.
Thank you for your assistance.
Best regards,
Jamaledd
