What _may_ be a very interesting tool for doing "real-world" I/O generation is to use the InterMezzo KML (kernel modification log), which is basically a 100% record of every filesystem operation done (e.g. create, write, delete, mkdir, rmdir, etc).
Peter, do you have any very large KML files which would simulate the usage of a filesystem over a long period of time, or would Tacitus have something like that?
