Are all USB-C cables the same?

No, not all USB-C cables are equal. USB-C stands for the shape and type of connector, which is the same for all USB-C cables but not all cables support the same kind of protocols and transfer speeds.

To use a Thunderbolt 3 product from Akitio, a Thunderbolt 3 cable is required. For the best transfer rates and to make full use of the Thunderbolt 3 interface, we recommend using a cable that supports 40Gbps.

To use a USB device with a USB-C connector, we recommend using either a USB cable that supports 10Gbps or a Thunderbolt cable that also supports USB 3.1 Gen 2.
