Currently, I am running FCP 5.0.4 on a PowerPC G4, OSX 10.4.11, soon to be upgraded to OSX 10.5.6. Within the next year, I plan to upgrade to an iMAC or MAC Pro and FCPX. Since FCPX won't run the old FCP projects, I'm trying to figure out a way to continue editing the old FCP projects, while starting new projects on FCPX. It would make sense to be able to keep the G4 HDD and physically transfer it to an MAC Pro bay or clone it to an external drive to run with the iMAC. Would I be able to boot to the old drive (or clone)and run the FCP 5 when I need to work on the old projects and then boot to the FCPX when I work on projects going forward?
If I go with the iMAC, it has only one FW-800 port. My FCP data files are stored and backed up on G-TECH external drives. That means I would need to use a USB 2.0 port to connect to one of the external drives (e.g., the FCP 5 HDD) and the FW-800 connection for the other (e.g., data drive). Would there be a significant difference between using the USB port for one purpose or the other?
