Re: System->Admin->Disk Utility->Benchmark results
The graphical display of the results of the benchmark, I think are not displayed correctly.
What may be more meaningful is having collected the data (read rates and access times) is to sort them in increasing order. That way the median (i.e at 50% of the time) would be the average. The lower and upper quartiles (and/or deciles) could also be determined from the dataset.
The upper quartile would then represent the read rate at which 25% of the data exceeds that amount.
The minimum & maximum values are less informative because they may have occurred for an insignificant amount of time. For example, if you have a maximum read rate of 200MB/s and it is the only reading above 100MB/s, then it isn't particularly meaningful.
The access times should be displayed in a similar way.
