This is my first post and I have researched this subject for a while now still to no avail. Maybe you can help me. I just ordered a new mac pro 2.8 with the primary purpose of doing video editing on Final Cut. (5-45 min. videos here and there). Because of my budget, I cannot afford the the $800 price tag on the apple raid card but I would like to optimize my rendering and writing times. A lot of the forums I have read do not distinguish between software raid and hardware raid. So here's my 2 questions. 1. Will I benefit from using the software raid in Disc Utility or would I be better off just using a separate scratch/write disc? 2. With such a fast processor and 3 gig Sata HDs, will raid 0 improve speed enough to make a significant performance jump anyway? I would use a separate hd for my programs and regular files. Any expertise that could be given on this subject would be most helpful.
