I also share the issues highlighted here. All of our projects end up on tape somehow, but many of the products we make here end up coming around again for re-editing for different clients. So we are left with a big dilemma of keeping the projects live for a very long time (not good at all for day-to-day edit storage), or chucking it all out onto tape and then recapturing as necessary (not good for fast turn around).
A hot swap sata-based solution would be great as each project could have a dedicated drive that takes up no more shelf space than a tape. If the drive fails we can always go back to our tapes.
Can Drobo work with just one disk at a time? Or are there any other caddy-based systems out there that could be just what everyone needs?
