Which has what advantage over directly changing the image?

And the old disc may be slow, but the relative speed (Speed in relation 
to total capacity) is much better than modern discs. IOW it only takes 
minutes to read/write it completly.

Some month ago i backed up some old HDDs (biggest was 4GB), it nearly 
took longer to switch on/off the computer and change the HDDs, than the 
actual time to copy the HDDs.
Even with just 10MB/s it's less than 4 Minutes for 2GB.
In comparison it takes over 3 hours to copy a modern 1TB HDD @ 80MB/s.
