Hi.
I have an MSI Gaming edge Z390 motherboard and have updated to Windows 11.
I have connected multiple USB 3.0 / 3.1 drives to the 3.1 port on the motherboard, and windows is unable to write data to drives any faster than 20mbps. It starts of super fast, and drops off after a second or so. Sometimes even stalling!
I have tried changing the drive option in policy to ‘better performance’ to speed things up but nothing seems to work.
Can anybody help me with this?

The 'super fast' start would be Windows disk caching. The rest suggests a hardware or possibly driver problem.
  • Tried different cables? (you said drives, but not cables)
  • Does the same problem happen with reads?

Yes. Even had cables that come with the external SSD housing for USB 3.1 and does the same. Even 3.1 flash drives do it. Read speeds are through the roof.
