There's some inherent randomness, and the benchmark isn't as careful as it could be. It could begin by reading from track 0 to eliminate the initial seek time, if any. But you can run it twice ans mostly ignore the results of the first run to get the same effect (of course the disk must not be used by other processes or the contents of track 0 will be flushed from the drive's cache. It should have a time arg so that it can run for longer itself... Bruce
