There was an experimental  sort layer plugin but I can't find it from 
QGIS 3x. Only on the web site.  Maybe it has not been ported to qgis 
3x.  Anybody???  I believe the "Load them all" plugin could help also.

https://plugins.qgis.org/plugins/SortLayers/

Some code found here could help.

Personally, I used Syncbacks free or SE.

You could always just copy and paste from one drive to the other.  This 
can work if you are not accessing the files from the drives at the same 
time.  Never *cut* and paste. That can be messy if things go wrong.  If 
you keep the same file structure, QGIS projects should work on the 
second drive. Your hard drive may also have a free software to do the 
job.  I would keep the first drive as a backup.

Cheers!

Nicolas
