Review on StarTech Computer Accessories & Peripherals for Computer Cable Adapters by Jessica Sanchez

Supports USB 3.1 Gen 2 (10Gbps) speeds and powers your devices over USB. Of course, you need a USB port that can provide speed and performance. Don't be fooled, 10 Gbps is shared across all 4 ports. Each of the ports supports advertised speeds, but bandwidth is shared. Of course, your device should be able to run at these speeds, don't expect an older USB stick to be any faster when you plug it in, and don't expect 10Gbps drives on all four ports as long as you can every single connect has full bandwidth.
