Hi Mark >>I suspect the performance differences you have observed are related more to software than hardware. The script's driven EIDE controllers are much newer than the SCSI ones, and I suspect that the OS drivers need time to catch up.<< Please have patience with my simplistic question. First of all I'm not sure about what the function is of the script you refer to. My level of understanding only goes as far as this: SCSI vs EIDE SCSI has enough intelligence on board so that the CPU issues a read or write or whatever command and the SCSI in effect say's OK, I'll let you know when I've done what you've asked. Thus the CPU is free to go about other tasks. Whereas with the EIDE situation the CPU has to control the operation from start to finish. Thus some of the CPU's cycles are occupied with controlling the I/O. Thanks - Emory
