Slow NVMe Speeds (PCIe 4.0 Downgraded to 3.0) Compared to Windows 11 – WD SN850X & Kingston
Hey all,
I'm experiencing performance issues with my NVMe drive, where it's not reaching the expected speeds compared to my Windows 11 setup. My max read/write speeds are capped at less than 4Gbps, which is lower than expected. Additionally, I've observed that the drive is being downgraded from PCIe 4.0 to PCIe 3.0 on Linux, as indicated by the terminal output. I've been attempting to resolve this and unlock the drive's full PCIe 4.0 capabilities, but the issue persists.
