On my nMP I am connecting an ATD and an ACD, and I also connect a Sonnet Echo Express III-D box via TB. Hence I have these connected to TBs 3, 4, and 5 (busses 1, 2, and 0). I also want to connect a LaCie TB SSD, and wonder which port to use??? I think port 1 or 2, as the Sonnet Box might actually utilise the bandwidth, and the ATD or the ACD won't. Any suggestions?
