Please check out this thread over here on the speed issue involving Private User Space vs Public share and how you can improve the speed, sometimes by 100X. Teracopy for the Mac is available, for free for non-commercial use.
My Cloud Home (MCH) actually creates two Public shares, one SMB and one AFP for the Apple Timemachine and both can be seen by a file explorer such as Finder. You don’t have to create the Public shares if WD Discovery is working properly which unfortunately sometimes it doesn’t with new updates and new macOS such as big sur. In that case you can try on your mac enter CMD+K (connect server) there you add “smb://my local IP” and it should connect. You can do the same for afp. The ‘my local IP’ for the MCH can be found by going to your router and look up the client list for DHCP.
