after upgrading my two PC to Windows 10 2004 I'm experiencing on both slow writing on USB 3 key encrypted with bitlocker.
With previous Windows version writing speed was about 20 MB/s, now speed swings from 8 MB/s to 0.
With the same USB key not encrypted the writing speed is about 18 MB/s, a bit slower than with the previous Windows version.
USB 3 chipset is not the same on the PCs, one is Intel and the other is ASmedia.
Any idea on how to fix this issue?
