I have been testing M-Logic's Thunderbolt RED Rocket enclosure for 3 weeks now and I am super impressed. I keep hearing about problems with the other enclosures but I can tell you the M-Logic is as solid as it gets. I use it with REDcine-X, Premiere, AE, Speedgrade, and Resolve and I honestly forget I have it plugged in because it just never gives me problems. I have tested it on a MacBook Air, Retina MacBook, and the new 27" iMac and I get perfectly smooth playback at 1/2 res on all.
I put together a little video demonstrating my super mobile Thunderbolt offload/playback system if you want to see the M-Logic in action.
If anyone has any questions or tests they'd like me to do let me know!
