We are currently in the process of building a FCP suite that we need to be able to smoothly handle 10bit 1080p HD Quicktime files without freezes and jumps in the footage. Ideally, we are hoping to install a RAID card and three additional drives under the hood of the Mac Pro and edit up to 100 minutes of 1080p HD without problem (in a RAID 0 configuration). Is this realistic though? Or do we need an external RAID array in a RAID 0 configuration to properly display and edit 100 minutes of 1080p HD? Any advice regarding our best purchase options would be hugely appreciated. Keep costs to a minimum is a priority too. Thanks in advance!
