It talks about 2 EIDE drives in a RAID 0 configuration. Quite frankly, the results were unimpressive. Besides that, This discussion is about single drive performance not RAID 0. Then I see that CPU utilizations to get these "marvelous" transfer rates (8 and I just shake my head..... 37.96% to achieve 8.09 MB/sec. That means almost 2 out of every 5 cycles are dedicated to disk I/O. By the time you add in the 1-2 cycles for NT to do its housekeeping you aren't left with a lot of CPU horsepower to do any actual work. Nice try. -- I've munged my address to help foil those insiduous spammer-type persons. Remove the _s to get my real address. jkotches@_pobox_.com
