You are hardly the first to make an observation along that line. Mr. Profitt was the first in this forum to say that all the way back in Nov 12, '17 and that revelation came to him at 3:00 AM after his struggle with the MCH for 3 months:
Alas, Mr. Profitt and most owners of the MCH don’t know its capabilities and should have either learned to use it or get rid of it early on. This is what is possible with the MCH with a little bit of software and optionally hardware modifications: dragging and copying 700 files with a total 300 MB to private KDDFS space that is shareable online and create a link and optionally delete folder from the desktop in 20 seconds at 110 MB/sec - something Google Drive, One Drive, Dropbox or any other cloud or NAS system is incapable of doing from the Windows desktop. If you are trying to reproduce that performance from macOS however, you may run into some roadblocks that Apple has put up.
