It seems like this question has been asked a million times, but after a few hours of reading similar questions, I have not been able to find a clear answer.
I have a mid-2012 Macbook Air running OS X 10.9. I want to run dual 24" 1920×1200 monitors and the built-in 11" screen.
Can I use a thunderbolt RAID device (i.e. Promise Pegasus R4 or anything else with two thunderbolt ports out) to drive two monitors?
Will this work:
MBA -> RAID -> 2x miniDP to DVI adaptors -> 2x 24" screens

No, not with the Promise Pegasus R4 has only two Thunderbolt ports. One you will need to connect to the MBA and then other to your miniDP adapter. You would need a Thunderbolt dock that has another Thunderbolt port or another video interface like HDMI, etc.
