First, let me start by saying that I have a very powerful machine I made a few months ago with 32 GB of memory, an AMD Ruzen 2700X processor, USB 3.1 etc. and one of the latest Windows 10 version (1903).
I have been trying for many days now to find a solution to the problem of slow copying of files on Windows 10 without any success.
I have read so many articles and implemented all the solutions without success. The Windows 10 continue to copy as slowly as possible. Max speed 1-8MB/sec (I use to have transfer rates from 80-120 MB/sec).
I had this problem before, some years ago and manage to solve it, but I don't remember how ... hmmm
I don't hope much, but who knows, maybe somebody may have a good solution for this issue.
Some of the "solutions" I have try with no success are:
Check the HDD and external media for corruption
Disable the Auto-tuning feature
Turn Off "Remote Differential Compression"
Use a different USB port
Install the latest USB drivers
Disable Drive Indexing
Disable the antivirus
Use the Disk Cleanup utility
Format the USB flash drive in the NTFS format
Change the drive’s Removal policy
Start in safe mode
Use a third-party application to copy the files (TeraCopy)
Reinstall Windows 10
You can't imagine how many thousand Windows 10 users have the same problem and ask for help on Internet...
No answers from Microsoft of course...
