I suppose you are looking for some ARM based solution, which I'm
interested in too.  (Disclaimer: I have never run ZFS with FreeBSD/arm
yet).

My biggest concern at this time is that no inexpensive board that I am
aware of that supports ECC RAM, which may be problematic over the long
run: ZFS replicates metadata and can recover from silent data
corruption on disks, however if the in-core copy have undetected bit
flip before being written, you would have big problems.  I personally
have that happen to my home storage system, which was later replaced
with a Asrock C2750D4I based storage system running -CURRENT.

Cheers,
