I don't know. The inital 80 IOPS (observed over about 2 full minutes) made me believe that 100GB would have covered a high enough percentage to at least eliminate track-to-track seeks. Are short-stroked seeks also that much faster compared to average seek times? And where would the steady increase in IOPS during the test come from? But you are definitly right when it comes to the test setup. I just started a test with size=1800g. Looking foward to what that will show. Thanks!
