This looks great as a portable NAS device. I could run it using Raspbian or whatever will run on the rpi. For me it would be perfect if there was a TrueNAS port to arm hardware that could run on the pi. As it is, I use a 2GB pi4 in an argon m.2 case as a traveling NAS. I run FreeBSD on that and it's not so much of a NAS as it is an NFS server.
