SuperSpeed USB 10Gbps (USB 3.1 Gen 2)
By incorporating the latest SuperSpeed USB 10Gbps (USB 3.1 Gen 2) technology, the SK-3501 U3.1 is able to deliver up to twice the speed of the USB 3.1 Gen 1 connection which runs at only 5Gbps. At the same time, with a corresponding USB-C to USB adapter cable, the device is also backwards compatible with the widely used USB 3.0 technology.
Reversible USB Type-C™ Connector with Power Delivery
The reversible USB Type-C (USB-C) connector enhances ease of use for connecting USB devices with a focus on minimizing user confusion for plug and cable orientation. The SK-3501 U3.1 supports power delivery (PD) over USB-C, providing 15W of power to laptops like the MacBook Pro (late 2016) that support charging from a 5V/3A power source. This allows you to work with the external drive without the battery levels of your laptop dropping even though the laptop is not plugged into any other power source.
