This is an absolutely brilliant cable. I previously used various USB-C hubs and USB-A to USB-C adapters but often they would disconnect randomly and/or provide very poor throughput. I use this cable exclusively for connecting my portable hard disks and it provides a solid connection with high throughput rates. It recognises my drives as USB 3.1 / 5Gb/s capable.
I cannot recommend this cable enough if you're wanting to connect your USB micro-b disks to 2016+ Macbook Pro's.
