Hello folks, I just placed an order for a 2.93 Quad core, a 640gb HD in bay 1, 6gb ram with a 4870 card(didn't want to buy and flash my own as this mac pro is a gift from a friend). I really want to get a 128 SSD as OS and app drive, but can't afford it. So I will just stick with the 640gb. I will most likely raid 0 two 1gb disks in bay 2 and 3 as a scratch disk for FCP, would it be a good idea to put my aperture library on there as well for faster speed? I have around 113gb of photos in my aperture library currently. Finally, I will use bay 4 as a back up for the OS and apps. I have a drobo for data storage. Thanks for your input!
