Proprietary storage? I'm skeptical. This is contrary to the open-source mentality: let the details of how the system works be known to everyone. Like PGP encryption: nobody's hiding how it works - in fact, more scrutiny helps prove it's safe. You don't hide the mechanism, you just hide your personal key. Otherewise, you start feeling secure based on your assumptions, like "only we can read these drives" - when maybe your assumption is wrong. Maybe somebody has hacked one machine somewhere and reverse-engineered the connector. Now you've got an unknown danger out there. Whereas if you're constantly submitting your system to public scrutiny, you'll probably only have known dangers. Which you can fix.
