Has anyone heard of somebody running dual ravens on a 2020 Macbook M1 17,1 using this Hyperdrive Hub?
Don't do it! Only buy items supported by Apple that you can buy from Apple website. i.e Belkin, OWC, CalDigit, Apple Multi Port Adapter.
If the dock says USB-C and works on Windows then it is not a good idea for your MacBook Pro. MacBook Pro is Thunderbolt 3 which is different than USB-C so be sure to only buy Thunderbolt 3 docks.
