I have two drives in my Quicksilver 2002 G4, one is a 250GB which can be fully used, the other an 80GB. Can U rid both of these drives and install two SATA 1.5TB drives? I do not want to use the PCI slots for a SCSI card and wire additional drives that way, because the transfer speed will be limited to 40mbps I believe. I have a Sonnet card a dual PPC 1,8Ghz card, a PCI USB 2.0 card and have other open PCI slots, but finally ran out of storage, and have a use for this machine to hold a LOT more. Other than the transfer speeds possible on SATA, are there any other differences between the original IDE (ATA) drives? Do they connect the same way? Any help?
