Have you logged it in Feedback Hub? https://aka.ms/AAdjzw7 Random Write Speeds are 4 times slower in Win 11 with Samsung NVMe "I have tested this with my 1TB Samsung 970 EVO Plus and 980 Pro NVMe in my ASUS F512DA Laptop. Under Windows 10 19043.1200, and using Crystal Benchmark, the Random Write (RND4K Q32T16) speeds were between 750-850MB/s. But with Win 11 .132 and .160 the Random Write speeds are only around 200MB/s on the 970 EVO Plus and 980 PRO. This is a 600MB/s decrease in Random Write speeds with Win 11 and needs to be fixed. EDIT : When doing a Record Diagnostic Info below, then the Random Write speed in Crystal Disk Benchmark is over 600MB/s, but when not recording Diagnostic info, it's back to 200MB/s. So it appears that something is happening when recording Diagnostic info for the Random Write speeds to increase."

Just now received another Mail & Calendar Update through MS Store On Beta Channel 22000.160 Check for it in the store, so far I don't see anything New.

Hi, Same version that came down yesterday on Development, today on Beta.

That is the version I have, but I couldn't say when. After a reboot the taskbar is hiding again, not stuck showing anymore. Will amend what I had put in FH. Cheers, Drew ![](https://learn-attachment.microsoft.com/api/attachments/6b0d0f55-0567-4140-83e3-ed20526c820e?platform=QnA

Thanks fg2001,

            For your reply. That's pretty fast from Dev to Beta in just one day, it must be hiccup free right 😊
