Size won't be an issue with DirectoryStorage, but number of objects is a
more important factor... If that 200GB is comprised of lots of small
objects, there are still penalties for storing filesystem metatdata for
many, many files (i.e. tens of millions) - this is why it is recommended to
use ReiserFS with DirectoryStorage.

OTOH, a 200 GB DirectoryStorage should not be a problem.
DBTab might be worth a look too, for "mounting" different storages at
different zope folders.

i've never run a storage that big so this opinion is worth the paper
it's printed on ;-)
