I don't have pictures. I can describe, though. Two disks were mounted in a frame linearly, both screwed to the frame, with the power/sata connectors toward the middle of the frame, and one drive upside-down. These cassettes were removable as a unit for hot-swap, and were inserted linearly into a half-deep 19" rack enclosure. That the two drives were physically connected to the same frame, and removed and replaced as a unit would make it seem as if they would be started in phase. Now I'm not physicist, but I'm not 100% sure that's so important - if you have two gyroscopes contra-rotating and firmly connected, running at the same speed, surely they resist movement by sheer gyroscopic effect?
