Most efficient/fastest way to see disk usage
 

Hi all,
I use this command to see disk usage:
du -cks * | sort -rn | while read size fname; do for unit in k M G T P
E Z Y; do if [ $size -lt 1024 ]; then echo -e
"${size}${unit} ${fname}"; break; fi; size=$((size/1024)); done; done

The data itself is around 200GB with lots of subdir and small files.
The command takes for about 1 hour to finish.

Is there a faster way to see the disk usage of some directories?

Secondary objective is:
To see which directories have changes (added/remove subdir/files)
comparing to the previous data. I'm thinking of using "ls -laR" and
"diff". But not sure.

Thank you.

Maybe something like:

find / -exec stat -c "%i %a %u %g %s %Y %Z %n" '{}' ; > before
then rerun after and diff...?
