I'm assuming that you used a SATA PCI card to do so -- what brand was it?
Also, what kind of G4 and what interface were the other drives on? ATA/66? ATA/100?
Reason being, I have a ATA/100 PCI card with a few special edition 8MB cache drives connected to it... I'd like to know how much better the performance is with an SATA card and drives as opposed to my current setup...
