Slow (~ 60 rpm), high capacity, 5.25" drive

how could you expect to loose only a few milliseconds ?? i understand what you are talking about but think for a minute … normaly backup drives even the most size  are with 5400 rpm… and you are talking about one with 60 ??? rpm   ONLY 60 O.o?   even the most old drive that i have is 100 megs from 1990 and its a 3600rpm drive lol  … 60 rpm drive would stop the computer completely from responding lol, errors and bluescreens in theory and the actuator arm would crash into the platters because of the poor lifting force lol
