I am using XU4 with Arch Linux Arm also and my Rock 64 just arrived a couple hours ago.
So far I managed to try only Samba using ayufan's Debian Stretch and it looks Rock 64 can easily beat my XU4 in terms of speed and stability.
Here is what I found when copying a 1.5GB file from Win 10 laptop with SSD to the USB 3 WD Mypassport drive mounted on the Rock 64 running Samba on ayufan's Debian Stretch.
Samba has not even been tuned yet and dmesg shows clean result unlike my XU4 which always runs into USB reset issues when the speed gets above 90Mb/s.
I do hope Rock 64 get the official support from Arch though.
