A while back I played with RAID-10 on 4x 3TB drives on a Late 2012 Mac Mini. I was kind of surprised to find it was significantly SLOWER with 2x drives on Thunderbolt and 2x drives on USB3 than just having all 4 on USB3. My question is with the new Mac Pro, if I have 2 individual Thunderbolt drives in software RAID 1, should they ideally be on the same Thunderbolt chain? Same Thunderbolt buss? Different busses? In this case the drives are only capable of maybe ~150MB/s each, but I'd still like to know the "best" way to maximize performance.
