Windows 11 has a serious problem with SSDs. Several users deplore indeed very degraded performance in writing, with benchmarks as proof. Microsoft will have to react as quickly as possible!
If the launch of Windows 11 went fairly well, Microsoft’s new operating system is still very young and users regularly discover more or less annoying bugs. The one that affects the performance of NVMe SSDs is not new, it was spotted several months ago during the beta test phase of the operating system.

But at the time, the bug was put aside precisely because of the beta status of Windows 11. Except that it is still present in the final version! Users are sharing their SSDs benchmarks on the Microsoft forum and on Reddit and there is obviously a problem with writing data, which in some cases is significantly lower than under Windows 10.
Regarding reading data, there is no change, the bug only affects writing. But despite the community’s investigation, there is currently no well-identified source that would explain this drop in SSD performance under Windows 11. There is, however, an interesting track: this bug affects the disk on which the operating system is installed. A secondary disk displays expected performance.
Microsoft seems to be aware of the issue, with the latest build of the operating system (22000.348) improving the performance of SSDs. But we are still far from Windows 10. Unfortunately for Windows 11, this problem is likely to overshadow it, just as it had been the case with the performance bug with AMD processors.
