Hi all, I'm thinking about this drive setup for my Mac Pro and want to know if you guys think it will be a good setup or if you have a suggestion for a better setup. RAID 0 on 2 Raptor 150GB drives (10,000 RPM) - This will be my boot drive and will store applications. I've read that this should provide substantial all around performance increase. RAID 0 on 2 WDC WD2500JS 250Gb drives - This will store my pictures/video/music. 2 External 500GB drives (haven't decided on models yet) to be used for backup/time machine. Not sure if I should raid these (or if possible). What do you guys think?
