WOW it's really wonderful SBC!!! As ZFS user, I suppose that the best testing configuration would be 5x4Tb hard disks in raidz2 pool, without de-duplication but with compression turned on, no GUI to save memory, 4Tb disks are more efficient in terms of dollar/megabyte than 2Tb models and if there would be slight performance issues one could choose to prefer 5x2Tb config or to deal with some slowiness
HI, kevinH! I bought the same TV box "A95X MAX", not considering to use it as a Linux desktop, but your post raised some interest inside of me I tried it and have same issues, often installation froze at expanding space on SD card, one time it gets to the point of login prompt, but I couldn't type anything. Also tried to expand the system partition manually before first booting process, but no success on bringing up this box.
