Answer to: A MOD, not a repair: Adding MORE than just one harddrive?I would be using a Mac Pro if I were you. Especially being a Film Editor. You would gain so much more by using the Mac Pro's more powerful CPUs and ability to have the space you need. If you really have to have the MBP, I would get the Pegasus R6 Thunderbolt enclosure. I have the 6TB version in Raid 5 (5TB useable space) and it works beautifully. Super fast transfers. I'm a working DJ and have almost 3TB of music on there. Plus Ableton projects eat up a lot of space too. Don't Eff up your machine on some crazy idea of 3TB of internal storage on a MBP. Quite frankly, that would fall into the "insane" category.
