I'm wondering if I get two 2TB firewire 800 drives (G-Technology, if it matters) and put them in a RAID 1 array if they will be too slow for video editing. Redundancy with video footage is of the utmost importance, and I would love to be able to that automatically. But some people say that you need a hardware controller or something to really do a RAID setup "right". Would I be able to set up two 2TB drives in Apple Disk Utility in a RAID 1 setup and still have enough speed for editing? Thanks.
