Back eons ago when I first started using digital hardware/software to edit motion pictures, the MO was considered to be a less expensive storage option (with its drive) than hard drives. It's hard to believe that a 450 MB hard drive would have about cost $1000 then. But, the technology for MOs wasn't perfected then (they became corrupted) as I lost some audio/video files in trusting them. I would guess that has changed, today.
