So I have a question, and please bare with me on this, but it related to the 4xTB3 ports on the new 2016 rMBP (15in version). We all know that TB3 is used in conjunction with the USB-C port design, and there are plenty of examples of dongles and hubs, but what is the limiting factor on these? If USB3 is ~5Gbps, USB3.1 is ~10Gbps, and TB3 is ~40Gbps, then how many devices can be powered through a single TB3/USB-C port? Is it basic math (4xUSB3.1 devices using one hub equals ~40Gbps which equals the speed of one port)? Or is it more complex than that? I'm sure people have asked the question, but in my scenario, I have 10 external hard drives of various sizes and years, all running a variety of USB2,3,3.1 along with monitors and other devices. Now I'm sure I can just go ahead and buy multiple docks if I wanted to, but how much can I plug into one port before I start to lose bandwidth? http://www.belkin.com/us/p/P-F4U095/ This dock by Belkin for example has many ports in their hub: 1. Gigabit Ethernet 2. Audio Out 3. 2x USB-A 3.0 4. 2x Thunderbolt 3 (USB-C) 5. DisplayPort 6. Power 7. Connection Status 8. USB-A 3.0 9. Audio Out) Wouldn't using all of these at once limit the speeds on each? And if not, can you daisy chain more hubs using the 2xTB3 ports?
