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.
To help with the second question, see
<https://www.samsung.com/ca/support/memory-storage/update-the-firmware-of-your-samsung-ssd/>.
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).
