For general specs, go here: http://www.pcmag.com/article2/0,4149,847716,00.asp and click on "Throughput Time Line" It has theoretical speeds of a lot of interfaces. (SCSI, IDE, USB & FW) My own testing seems to show that the PCI bus could be the limitation, and various posters here have said that IDE is faster, and some have said that SCSI is faster. Benchmarking programs tend to show that newer drives are faster, but a real world test (transfering a single contiguous 420 MegaByte file to Ram) of old and new SCSI and IDE drives were all pretty much the same. My personal recommendation is that if cost is an issue, go with IDE. If you want faster, go with a SCSI card and newer SCSI drives. I'm not a technician, so I can't tell you about overhead and other such issues. Anyway, check the web site. I'm pretty confident that I can say that the fatest common setup would be a raid of multple SCSI 320 15,000 rpm hard drives. Don't ask me what that would cost though. ;-)
STeve << Is there much of a difference in speed between using a 50pin scsi drive (or indeed a with an adapter 68/80pin drives) vs IDE drives on the internal bus of a Pre G3 - PCI Power Mac. Or is it mainly a cost per megabyte issue in that the larger IDE drives are a lot cheaper. At what point (which version of SCSI) does SCSI become faster than IDE say ATA66/100 with a 7200 drive? >> -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
