After 10 hours of preliminary research, we tested more than 25
USB-C accessories to put together this guide to the best ways to
connect peripherals and devices to a USB-C–equipped computer. It’s
by no means exhaustive. USB-C can, in theory, replace every other
port, and there are a seemingly infinite number of port
combinations you might encounter. We focused on the most important
tasks you’ll likely face, such as connecting older peripherals
like hard drives and hooking up an external display.
