Hey guys, I have been waiting for a thunderbolt upgrade to the mac pro for almost a year now and I think I am ready to look into alternatives, as my machine is still pretty fast. I currently have a 16 TB Drobo Pro connected via FW 800 for streaming video to the Pro and multiple Apple Tv's throughout the house. The Drobo is really starting to get slow and I am just about out of space so I need to start looking into alternatives. I read an article about SAS Raid Cards and how that could possibly be my solution, but I know very little about this kind of setup. (http://www.pauljoy.com/2012/07/mac-pro-thunderbolt-dilemma/) I don't know how practical an option like this (http://http://tinyurl.com/9g5xzgd) would be for me. Would running a setup like the ProAvio be as simple as the Drobo Pro? I also like the dual disk redundancy of the Drobo Pro. My real question is: Should I get another Drobo (which would be pretty slow), a SAS Raid setup, or wait for thunderbolt and go with something like the Promise Pegasus?
