The G3 has to access data between to busses - from its IDE controller and from the ATA card recognized as a SCSI device on a PCI slot, a kind of round about way data is tossed around.. Also the onboard controller represents the IDE standard of the day (when the G3MT was designed) being ATA-33 vs the ATA-100 card capable of faster transfer rates. You remove a bottleneck by using one kind of controller for both drives. >2. I was afraid this might be the case. No big deal. . .just the lazy >streak in me coming out. >3.
