doh, I meant the differentiator between your idea and mine would be that I would take mine offline (so of course I didn't put that part in...). Mostly for power considerations. With hot swappable drives and robot loaders I don't see a need to waste power keeping them live all the time. Automated refresh routines to ensure data integrity once a week/month should be sufficient.

and yeah, still no where near $12,000 a year per movie for storage.
