^ The Satechi only uses one USB-C port. I have the one without the SSD slot, but I am pretty sure that one also uses only one slot. The other nice thing about it is that the size and color, even the texture, match the mini pretty perfectly, so you barely even notice it's there. The power lights are also the same color and line up vertically. A very well designed accessory that hasn't given me any problems over the nearly year and a half that I've owned it.
