Good thing we're all switching to USBC for everything, apparently, since it doesn't have that problem. http://www.informationweek.com/mobile/mobile-devices/usb

Yeah, my head started to hurt when you add Thunderbolt 3 to the mix. Then you've Type-C for USB 2, 3, 3.1 -- and 3.1 gen 1 is really 3.0 re-branded. You need to look for "USB 3.1 gen 2" for the 10 Gbps support in the cable, and don't forget charging requirements -- the Belkin cables they sell at the Apple Store only support up to 60 W, but others, such as https://plus.google.com/+BensonLeung/posts/TkAnhK84TT7 https://plus.google.com/+BensonLeung/posts/TkAnhK84TT7 claim support for 100 W or more. Then you've Thunderbolt 3, where you can theoretically hit 40 Gbps, but where cables that support those speeds are basically 0.5m, except one Belkin that's 2m but doesn't support DisplayPort or USB 3.0. And finally, the white USB Type-C cable Apple sells and ships with its power adapters is called a Charge Cable and doesn't support data, like connecting two Macbooks together to do Migration Assistant. But that's okay, because even if you do connect two computers together with a 0.5m Belkin TB3 cable, you won't hit 40 Gbps. Using Migration Assistant, copying 256 GB off a disk capable of 3.1Gbps should take about 11 minutes, but it always takes 2 hours when using cables between two 2016 MBPs -- Ethernet gave me the same speed as that 0.5m TB3 cable -- and it's about a half hour shorter if you use Wi-Fi for a direct connection. Given that, I can't wait for the day when we replace all these confusing cables with new directional wireless standards...

  One of the missed opportunities of WIFI Direct was that they didn't specify a transfer protocol as part of the spec...

  Target Disk mode has always been much slower than a native drive for me, right back to the SCSI PowerBook days.
