I have an Asus p166 with: 2 - 2 gig EIDE hard drives 64 megs ram Adaptec 2940/UW SCSI card Phillips 8x SCSI cdrom #8 771 video card Sound Blaster AWE32 I originally had a Toshiba 8x IDE cdrom, but had no luck getting it to work as either a slave or a master on either the primary or secondary drive. After I got everything set up, I attached a Quantam Capella SCSI drive to my system for benchmarking. I saw almost no difference between the SCSI and EIDE drive perfomance numbers. The motherboard uses the Triton II chipset. I have been told that this is the reason the EIDE performance is so good. This test was run with no other users on the system. If you are only going to have a couple of users on the system, then EIDE is far cheaper. If you anticipate a high load on the system, then eventually the EIDE will drop to it's knees. The SCSI system has a major advantage in that it places very little demand on the processor for IO requests. If it's going to be a coupl user system, use the EIDE. If you're going to have a lot of people on it or use it in an application like a web server, then go SCSI. As far as the SCSI cards go, it depends on what you want to do with it. If you are going to use it for a primary disk controller, then get the PCI version. If you are just going to hang a tape drive off of it, then just get an ISA controller.
