What to do with Windows 11 SSD slow?

I have a Force MP600 SSD running on a Ryzen 5 5600x. In Windows 10 I had a benchmark of over 8000 points, in Windows 11 just 5500 points.
The 4k-64Thrd write accesses in particular differ massively.
In Windows 10: 3206 MB / s, in Windows 11: 755 MB / s.

The other write and read accesses are roughly the same.

What can that be? Is there anything I can do with it?

Most SSDs now have the TRIM feature enabled by default. If you want to check if your SSD has the TRIM feature enabled, you can follow the steps to check it manually.

1. Type cmd in the start menu, select Command Prompt from the list, and choose Run as Administrator.

2. When the command window pop up, type “fsutil behavior query disabledeleteNotify” and hit Enter.
