Internal Disc Burners
When you decide to buy one of the internal disc burners then there is no need to worry about the Fire Wire and the USB. The connection might be either SCSI or the IDE. The latest model of the G4 towers contains the internal fire connections too. So you can install the internal fire wire disc burner. When you choose the external burner then you have 3 choices; the SCSI or the Fire wire or the USB. But it is better to avoid the USB connection since it is very slow. The best choice is that you should opt a Fire wire disc burner.
