Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
As you see above, the other performance is about the same, but in RND 4K Q32 T16 the speed has dropped significantly. I know that because the two software versions are different and the condition of the computer is different, it is normal for the performance to fluctuate, but this performance also dropped too much, and the performance remained stable low after many tests at different times.

Same here - this update fix nothing...
I am already updated to the 22000.348 patch. Sadly it did not fix the issue for me. My above benchmarks are taken on that version.
To further illustrate my system:
Running all latest updates including de latest build.
Windows 11 22000.348
Asus ROG B550-E Strix
AMD Ryzen 9 5900X
G.Skill Ripjaws V 32 GB DDR4 @ 3600 MHz C16
Gigabyte Aorus RTX 3080 Xtreme
Samsung 980 Pro 2TB (Latest firmware 4B2QGXA7)
Samsung 970 EVO Plus 2TB (Still on firmware 2B2QEXM7; Samsung Magician is not showing the 4B2QEXM7 firmware update yet.)
Same issue here - new build, fresh Win 11 install, 2 x Samsung 980 Pros.
Like a lot of people, the non-OS drive is fine, but the OS drive Write IOPS are only 20% of what they should be. It's noticeable in general use.
Here are the benchmarks with all Windows 11 updates and SSD firmware up to date.
OS Drive (C:)
Secondary Drive (D:)
As you can see, the OS drive is significantly down in all benchmarks, but the IOPS write is trashed.
