Several drivers seem to be affected by different issues, and the problems vary from user to user.

Reduced speeds 

Some users have taken to Microsoft’s own forums to complain about the decrease in solid-state drive (SSD) write performance that Windows 10 has caused, with reductions in speeds reaching as much as 50 percent.  According to the Reddit thread that also touches on this issue, Neal Christiansen addressed the matter and indicated that Microsoft is currently working on the issue: Here are also some threads in the Windows 11 Feedback Hub that also highlight the NVMe issue: 

[NVME] Poor Peak Write Performance, Write IOPS and Latency Nvme m.2 and ssd 4k random write speed halved and read access time tripled in windows 11.

Users experiencing the issue can only wait for a fix from Microsoft, and will likely have to wait until the company’s January Patch Tuesday to get it. However, there does not appear to be a workaround for now.

Windows 11 performance highlight

Performance has been a point of conversation about Microsoft Windows 11 since it launched in October. While the OS promises better performance than Windows 10, the OS does not seem to be living up to that promise. However, Microsoft confirmed that it will make the necessary changes to enhance Windows 11 performance, but users have to wait until 2022.  Have you experienced NVMe performance issues before? Share your thoughts with us in the comment section below. […] Internally, in addition to wanting to focus some of our UX framework’s time on perf in 2022, we also have a dedicated team formed recently to tackle this topic more holistically. So there are multiple things we’re collectively doing here to try and make sure we have a good perf story.”
