Will there be a USB-C to thunderbolt 2 adaptor? I only need data transfer to be higher then USB 3.0
In specific. Thunderbolt can carry USB but USB cannot carry thunderbolt. 

In general, as long as your Mac has any Thunderbolt connector, it is highly likely you will be advantaged to connect over thunderbolt instead of using USB. For my money even Thunderbolt 1 is superior in many ways to the best USB 3 chipsets we have today. Now - the above statement is going to be obsolete soon since the newest Thunderbolt 3 chipsets and USB Alternate Mode Functionality mean that USB can be other protocols and TB3 looks to be an awesome step forward for simplifying the need for adapters that you would need on Thunderbolt 2 to get USB 3.0 connectivity today.


What Thunderbolt to USB 3.0 cables/adapters exist for OS X and Mac hardware?
