Typically on DMA disc-to-disc copies on my IDE drives I'll get *lower* CPU loads than for the SCSI drives on the *same* systems. The copies will of course take longer to complete on the IDE drives, I guess the total of CPU cycles burned won't be very different but I haven't spent a great deal of time worrying about it. > What about USB cards? You can expect the processor load to be very significantly higher with USB devices. 73, Ged. ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
