I am using it on an Intel J5005 with SATA SSDs, managed through Docker. Works flawlessly.

If I were to upgrade, I would choose a board with a modern PCIe 4.0 M.2 Slot, because i’d like to put the database on fast NVME storage.

It’s absolutely awesome and rock solid. It even allows for not syncing deletes, a sort of append-only backup in regards to files. Very handy for photos and especially large videos, because deleting them locally won’t delete them remotely! And if you only sync in one direction, they stay off your phone. You can take as many videos as you want without filling up your phone.
