Until 512 MB.  However, you can change the default partition size in
FileStorage.py.  Note that it behaves correctly with partitions of
varying size, so you don't have to worry that it'll get confused if you
set it to a partition size of 10 MB when your first partition is already
50 MB.

BTW, Evan helped me find and correct a bug.  You'll only run into it if
you set your partition size to less than the size of the largest ZODB
objects.
