Do you need to have the RAID card installed if you only use external RAID drives and don't use the internal drives? I'm new to RAID.

    No, absolutely not.
    This card is only if you want to use the internal drive bays in a Mac Pro to have a RAID 5 array.
    If you want anything else on the internal drives (RAID 0 or RAID 1) and you're better off using Disk Utility.
    If you've got an external RAID chassis, then you use the RAID hardware in the chassis, not this card.
