Unexplained NVME drive slowdown in win 11 new computer


hmm couldn't even guess then. Are you sure bitlocker is off? Open a command prompt and type "manage-bde -status" Should show that drives are %100 unencrypted. If they are then I'm not sure what else to suggest other than try Windows 10 and see if it's better. I also had my nvme drives randomly disappear with Windows 11 and hasn't happened once with 10 yet.

I updated my previous comment, the behavior is, interesting, the file transfer starts out at 30mpbs for like the first 15-20% and then shoots up to 3.5gpbs for the remainder of the transfer. I will double check via command prompt to be sure, thanks for the suggestion!
