If you want to check the integrity of the entire 100gig of data, then
you're going to be checking 100gig whether you do it as a one big file
or as lots of little ones.

Observations:
If you're only after integrity, use cksum instead.  it's a lot faster.
 Use MD5sum only if you think someone made changes they're trying to
hide from you.

If you check lots of little files, you'll find out which one is bad,
rather than finding out "one of the set" is bad.

Are you only interested in the file contents, or the attributes
(c-time, a-time, etc) as well? Makes a difference if the target
filesystems are different...

If you challenge a bunch of TriLUG geeks to write the script to do it
on a single line, the taks of writing the script might become
trivial...
