A: When splitting up a USB-C port, it limits the capabilities of all the ports, and although you could plug in one drive, the hub is meant more for lower-powered devices.

We can confirm that the USB-C port on the hub adapter is meant only for power-delivery and will not support data transfer or video output.

If you are able to connect an external drive, we would recommend only connecting it to one of the USB-A ports and to connect only one external hard drive at a time as two will require too high of a power draw from the hub adapter and may not function correctly.
