So I just purchased a refurb 2015 15 rmbp and I need some advice. I'm building my setup and im a little confused when it comes to Thunderbolt, I Plan on buying a Dell up2516d Monitor it has a USB 3.0 hub built in,I want to attach a external ssd via the USB 3.0 port ,will that work? Can thunderbolt 2 pass USB data? I see dell monitors as a alternative to apples discontinued monitor but is display port 1.2 the same ? I've looked through the forums and google but can't seem to find a definitive answer.
