Move a lot of files with little to no read/writes to drives?

What I would like to know is what is the best method that will allow for me to rearrange everything without causing a lot of read/writes? I'm not wanting to move the files from the one disk to another, they can stay where they are in that context, I just want to move them one folder/directory.

Example:

/mnt/user/shareA/Movies/Bond and moving those fills to /mnt/user/shareA/Movies. Keeping files within the same disk/share

From looking around I seem to found these options:

• benhex-krusader app
• Unraid CLI using mv command
• Using midnight commander from the CLI

Any other suggestions or guides would be helpful. Final purpose would being able to use radarr but it does not work well with nested folders.
