Hi I´m a cameraman that have just started to have to edit more and more. We have just got a Mac Pro and have already edited to 30 min sports programs on it. We had very little time to set up a system before we started our first edit and now I would like some help and pointers. We have the stock hard disk and added two Seagate Barracuda 750s. I cloned the OS and all aplications from the original Harddisk to one of the Seagates. I have a feeling this was not the right thing to do. I have a 2T Mybook Premium extern hardisk coming in the next couple of days as well. How about software RAID, will I benefit from that or do you need to get the RAID card? LethalWolfe, may I ask for your help?
