It looks like the Mac Mini is generally designed for usb-c devices. Does anyone know the answers to the following: 1. Does plugging a usb device into a thunderbolt port make it run better than in a usb port? Does thunderbolt have lower latency than usb? (this is for the SD card, the slot they took out used to be hooked up to the PCIE interface) 2. Does leaving things like the heavier flash drives on the end of short adapter cables hanging from the usb-c ports cause strain on the ports themselves?
