Remember that 800GB is the *average* maximum amount. The amount of
compression you get on a given tape is entirely dependent upon the type
of data you back up. Text files compress more than binary files, and
database files compress depending upon how full the file is.

500GB is about the real-world average. You'll notice that you may even
get the occasional tape that gets more than 800GB.
