The best of both worlds would certainly be a central, fast storage filesystem, coupled with a hierarchical storage management system. Oh wait, it might exist already... Well, at least it's in the works: Sun and CEA are working on implementing such an HSM for Lustre 2.0. See http://wiki.lustre.org/images/8/8b/AurelienDegremont.pdf for details.
