The second misconception about Type-C is its supposed ability to do transfers at the speed of light in comparison with older solutions. Again, that’s not true — USB 2.0, 3.0, and 3.1 are industry standards separate from the type of the connector (Type-C in this case). So don’t expect to need less time to download your giant library of photos to your laptop if you get one.
But say you got yourself a USB 3.1-compliant Type-C cable, would that do the trick? Sure, it’ll be theoretically possible to reach that 10Gbps limit, but not really, as a long list of bottlenecks will stop you from getting there. Whether it’s an older, slower USB port on your computer, slow storage (on both ends), or something else, assuming that you’ll suddenly be able to upload the entire season of House of Cards in 4K to your smartphone in seconds is a pipe dream.
