After looking at the new Hitachi DVD Recorder (uses 2x500GB disks to store data on it) I was wondering how feasable a Quadary(?) system would be. If you put two hard disks (or memory sticks, whatever) together, you can store data in a quadary system. 0 = 0 on both disks; 1 = 1 on disk A, 0 on disk B; 2 = 0 on A, 1 on B; 3 = 1 on both disks.
Just a idea.. have to go before I can look into it… Any ideas
