I know that his has been discussed before in detail, but I cannot remember those details and I haven't been successful in trying to search for the discussions. I thought that I understood how TB and TB2 works, but I no longer think so, so I would appreciate some thoughts on this. Let's say I want to connect a 4K display to the Mac Pro and a Thunderbolt 2 enclosure with two SSDs in RAID 0. Anandtech's 2013 Mac Pro review tells me that daisy chaining the 4K display off the TB2 enclosure is not a good idea. Fair enough and I understand that so far. Great. Not on the same chain. Got that. But what happens if I put the TB2 enclosure and the 4K display on the same bus, in other words, on TB bus 1, port 1 connected to the 4K display and port 3 connected to a TB2 enclosure, for example? Then let's take this question and say I want to do the same on the latest iMac, which only has one TB bus (unless they have changed this for the riMac, which I don't think they have). Reading through the 2011 iMac review, I am left confuzzled just how much the above scenario will be handled.
