Question MSI Z370M Gaming Pro AC - Very slow data transfer speeds through rear IO USBC port

[MrJonno]

I seem to be unable to achieve anything higher that 19MB/s transfer speed through the rear IO USBC port. I have tried with a number of USBC devices (flash drives, external HDD) but they all seem to cap at 19MB/s. I have tried updating my chipset drivers from the MSI support page, but after running the setup and restarting it made no difference.

I would appreciate any advice and thanks in advance

to have a look what the problem could be, plug in a USB 3 capable USB drive:
run userbenchmark.com and post the http link of your result, e.g. https://www.userbenchmark.com/UserRun/28977730

eventually update the BIOS of the motherboard

Thanks for the quick response. I have run user benchmark. Where would it show the results you would need to see?
