More simply to the point, Thunderbolt is not USB. Neither Multidock was even recognized and I learned the hard way that Thunderbolt 3, despite having the same format, is NOT USB C.

I originally hoped and tried to connect the Multidocks via Apple's Thunderbolt 3 (USB C format) to Thunderbolt 2 adapter, then into the Thunderbolt ports on the Mac via standard thunderbolt 2 cables, hoping to get that sweet 20 Gbps Thunderbolt 2 speed, but no dice.

Please correct me if I'm missing something glaringly obvious and advise as per below if you can!Īs you might know, the Mac Pro 2013 has 4 USB A ports and 6 Thunderbolt ports. The problems with the new Multidock 10G are that it is MUCH slower than the older thunderbolt model and cannot be daisey-chained as far as I know-a downgrade in every respect.

As a result I was forced to buy 2 of the new Multidock 10G units (USB-C), and am having difficulty figuring out how to best connect them to the duplicate Mac Pro late 2013 trashcan in the second studio. Unfortunately the Multidock 2 thunderbolt was discontinued and I literally can't find it anywhere in the world, not even eBay. These work brilliantly and deliver thunderbolt 2 speeds of 20Gbps (lightning fast) with NO ADAPTERS-just one single thunderbolt cable going into just one of 6 thunderbolt Mac ports for both daisy-chained Multidocks. In my original studio I have a Mac Pro late 2013 trashcan connected to 2 daisy-chained Blackmagic Multidock 2 (thunderbolt 2) units (the older, now discontinued Multidock model). I am in the process of duplicating my rig for a second studio. But since the MultiDock 10G uses SATA 3 (6 Gbps) based connections to the actual drives themselves, the maximum throughput possible to a single drive is even lower, usually around 500 MB/s maximum after accounting for SATA interface overhead (and could be less depending on the drive).TL/DR - How do I connect two Multidock 10G's to a Mac Pro late 2013 to achieve minimum 20Gbps speed? Specific cable/adapter path appreciated.
USB 3.1 Gen 2 bus speeds are 10 Gbps (1250 MB/s) at the interface level, but due to overhead and other issues, real world maximum performance you can expect at the port level is around 900 MB/s or so. Sometimes this is due to connection related issues and disconnecting and reconnecting the cable improves things.Įven with USB 3.1 Gen 2 speeds, things are never going to be as fast through the MultiDock 10G as with the internal SSD.
I've also seen situations where USB 3 capable ports don't always negotiate USB 3 speeds (even when using a USB 3 compatible cable). For example, a lot of USB-C cables designed for charging purposes only support USB 2.0 data speeds as they lack the additional data wires internally to support USB 3 data transfers. Usually the causes of this are some kind of cable or port issue. Although USB 2.0 has a maximum interface bandwidth of 480 Mbps (60 MB/s), due to interface overhead (and a few other factors), have real world transfer speeds in the range of 35 to 40 MB/s, which seems to be inline with what you are seeing. It sounds like the MultiDock 10G is only connected to the computer using USB 2.0 speeds (480 Mbps) rather than USB 3.1 Gen 2 speeds (10 Gbps).
