Hey does anyone know what speed ATA bus the original G4 mac minis (1.25/1.42) were on. I know the hard drive is ATA-100. Is the optical drive also on a seperate ATA-100 or is it lower. I need to know if I'll be able to shove in a flat blue ray burner inside in the years to come to backup my media.

See http://developer.apple.com/documentation/Hardware/Developer_Notes/Macintosh_CPUs-G4/MacMiniG4/2Architecture/chapter_3_section_2.html for a diagram of the Mac Mini G4 architecture.

From the article - "The Ultra ATA/100 interface supports the hard disk drive as the master device 0 and the optical drive as the slave device 1"

Having two high-bandwidth devices on the same ATA bus may not be such a good idea. You may want to consider using an external firewire enclosure instead.

Well that's not too bad, considering the fastest ATA 2.5 inch drives max out at 50MBps and even the fastest optical drive speeds can't break 30MBps yet. That leaves me with 20MBps.
