The original post says "HD", as in hard drive, not SSD flash storage. 
As usual Jolly Roger didn't bother actually reading the question.

Having noted that, defragging isn't really neccessary on MacOS hard 
drives either.

     Do Mac hard drives need to be defragmented?
     macOS does not include a built-in defragmentation tool
     because it is deemed unnecessary. macOS is designed to
     handle file fragmentation automatically, especially for
     small files. Using an external defragmentation tool on
     a Mac is not recommended.
