I'm looking for a USB-C to two USB 3.0 port adapter for backups & it should have a USB- C charge port.

I like to sync external HDDs with full USB3.0 data rate using the rMB. Is this possible?

USB 3.1 SuperSpeed+: 9697Mbit/s (1212 MByte/s)
USB 3.0 SuperSpeed: 4000 Mbit/s (500 MByte/s)

Any experience?

Looks great. But my concern is that the exchange of data between two usb hard disks on this adapter will be very slow.
I'm very excited about your experiences.

USB 3.1 on the MacBook is Gen 1, thus supporting only 5 Gb/s. You'de need USB 3.1 Gen 2 to get 10 Gb/s.

Regardless, if you have spinning hard drives, you won't be bottlenecked by USB 3.0. You need a (good) SSD to fill this much bandwith.
