We store a WHOLE lot more binary data in our DBs than that. The
big advantage to us is that we store the data in TEXT fields, and
use Slony to replicate it, so in the event of hardware failure, we
don't have to worry about the DB looking for data that isn't on
the file server.

Never measured the actual performance difference, but we haven't
had any performance issues with keeping the data in the DB. I'm
sure keeping it on the filesystem is faster, though.
