I own a Mac Pro but my model does not have a USB 3.0 port. I feel really inconvenient because USB 2.0 is so below standard now. However, my phone uses USB 3.1 Type C, which is clearly where the future is heading towards. So I want to skip USB 3.0 to Type C, just so that I am better prepared. Plus, I get all benefits from Type C and I can just buy an adapter for my old USB 3.0 devices. A problem is that I can't really find any card that I can buy... There are very few PCIe cards for Type C right now, and I don't know if they would work with a Mac Pro... Does anyone has a similar experience that can help me out?
