Back to school ;) You're confusing hard disk throughput with PCI bus and front side bus (FSB). The hard disk throughput terminology is written as ATA f.e. ATA33 which means 33 Megabytes/sec (like the B&W G3). PCI bus has it's own bus, almost all modern Macs and PCs have a 33MHz - 64 bit PCI bus. So all installed PCI cards run @ 33Mhz. Also the AGP bus used for video cards is always 66MHz. FSB thus the system bus differs f.e. 100MHz for a Sawtooth to 800 MHz for a newer P4. So the Sawtooth has a 100MHz FSB, an ATA66 interface with a 33MHz 64 bit PCI bus and a 66Mhz AGP bus. Get it? :) > And any hard drive connected to the same bus as the CD-ROM would run slower > than the other hard drives. The unwritten rule is to never connect an HDD and an optical drive to the same IDE channel, otherwise an HDD would be slown down, that's the rule I always use. But IIRC the ATA standard has been changed for a while, but don't know when that was changed exactly. It seems that nowadays connecting an ATA33 DVD burner and an ATA100 (or ATA133 like the Maxtors) HDD to the same channel, they both operate at there own speeds. * * -- G-List is sponsored by <http://lowendmac.com/> and...
