Please forgive as this is a quasi-cross posting from the iMac thread. I know many professional videographers hang out here in the Mac Pro thread and I appreciate your real world perspective as a fellow professional, if you happen to be one. Seeing they are just about the same price, curious if getting a 512GB Evo 850 SSD as an external drive and running my After Effects and Premiere Pro cache from that and then the smaller internal SSD drive would be the best value. (considering buying the iMac 5k i7 with M295x, 24GB RAM. Or a refurb Mac Pro.) Other than launching applications faster with a pure SSD, would I see an advantage of the SSD over the fusion? I'd like to store and render out the source files on the fusion drive if i get that. I also use Dynamic Link a lot in my projects, how much does SSD play into that?
