Only in very few situations do you get conditions where sustained transfer rate would be dominant. i..e where you are doing sequential accesses with large transfer sizes. Typical workstation access is random access with relatively small transfers. It only takes a few seeks to some other part of the disk to screw sustained rate. Your theory is contrary to my own work on disk performance and all the "established" thinking I have ever seen. So unless you have a convincing argument or some hard figures, your theory sounds like an idle assertion. -- Bob Cousins, Software Engineer. Home page at http://www.demon.co.uk/sirius-cybernetics/
