I am looking at the BananaPi M2 Ultra with its quad core, 2GB mem, and
native sata. Plus affordable for my budget. They are going to be for
servers, so the Mali GPU should not be at issue.
Looks like there's reasonable support for it upstream although a quick
look I don't yet see ATA support, not sure of the status there.
Other than I have a mess of Cubieboards, which one works better as a
desktop unit.
Do you mean desktop support for Cubieboards or any device in general?

How can I 'see' my swap partition? Free shows a 487304B swap with none
used. Yet.
Nothing in fstab. Guess I better read up on zram.
It's created as part of the zram-swap service. The swapon (no options)
will show swap details, the zramctl cmd (no options) will show you
size, utiliation, compression ratios etc.
