http://support.apple.com/kb/SP63 says that you have a bus speed of 167MHz (really just memory/cpu speed), an ATA/100 disk interface and four 64-bit 33MHz pci slots. I'm going to assume that you are concerned about using a ATA/133 pci disk interface card. If it's a 32bit (short) card it's only going to run at 33MHz. That means it may sustain a maximum throughput of 133Mbits, and just keep up with a ATA133 interface. If it's a 64bit (long) card then it will do double that so no problem (64bit cards are always going to get the best out of the G4's 64bit slots). You must have an ATA133 speced hard drive to make this improvement. PATA drives are getting rare and ATA133 even rarer. The speed improvement would be very marginal, and I would recommend looking for a 64-bit wide SATA interface instead, which would mean you can use a modern SATA drive with a big cache and a fast rotational speed. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
