At least double that number it if you want to use Coda backup volumes.
They share the on-disk data files, but the metadata is copied. I also
prefer to have something like 20-40% overhead, the RVM allocator isn't
always the brightest in the world and because of the persistence RVM
tends to fragment over time.

Also spread your files across multiple volumes. Some advantages are,
when a file is 'moved' across a volume boundary we return EXDEV, and mv
does a copy/unlink, which resolves more reliably than cross-directory
