In the latter case, there _is_ a very significant difference in transfer speed.jbone wrote:(For all practical purposes, the performance difference is negligible.)
Actually I don't think you'll notice a REAL LIFE difference if you go ATA100/133 drive on a ATA/66 controller. Butttt there is a difference if you go with ATA100/133 on a ATA33 controller.
I have a ATA133 drive on my server, which has a ATA33 controller on it and performance is lacking.. The drive bursts 9megs.. which is horrid :p
I think the problem really is that the computer likes to allow DMA mode one day, then switch the drives back to PIO mode the next... IT'S VERY FREAKING ANNOYING...
But really alot of drives are going to have sustained transfer rates over 33Megs...
