We are currently using Rev Disks to back up our Final Cut Projects when they are finished. We have the older version with the smaller capacity of 35 GB. They are somewhat exspensive, and I was wondering what people thought of using external HD's as a back up system. So instead of place the full Rev Disks in a drawer, we could put the external HD on a shelf. It seems like it would be a cheaper solution, the only draw back I can see is having 10 times as much data in one place (that could be lost)....Let me know if anyone has any suggestions. Thanks!
