Windows 10: Robocopy speed question

I have 2 large files total 210 GB being copied by Robocopy between 2 external drives. Task Manager under "Disk" indicates a transfer speed of 30 MB/s.


A straightforward calculation indicates that it should take 117 minutes to complete the transfer. In practice, however, I am noticing a time to completion of about 250 minutes, or more than double the theoretical calculation.


Can anyone please explain this large discrepancy or, alternatively, suggest some way to improve on this performance? With Robocopy I use switches /mir /xo /mt:80.


All suggestions appreciated.

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Windows 10 file transfer

You write "the file transfer speed drops to zero", yet the xcopy command does not provide you with any feedback about speed or progress. I suggest you do this to drill down a bit further:

• Examine the event logger (as mentioned before)
• Use robocopy instead of xcopy:
  
  robocopy F:\ D:\ /s
• Repeat the copy process on a different machine

Thanks. I
