I’m looking for an off-the-shelf 4 or 6 bay NAS with upgradeable RAM that runs TrueNAS (for ZFS). The QNAP TS-664 looked very nice, but the price of the 4G version (with 2 RAM slots) is currently 25% more than the 8G version (with soldered RAM). I’d like to have 16 or better 32GB of RAM.
Do you have any recommendations?
Yep, this board looks perfect for your stated use case! You give up a bit for the form factor, but just put those sweet sweet power savings towards your next upgrade.
One last thought - I’ve watched a few reviews of the Jonsbo N1 and I think there were 2 flaws with it: loudish stock fan, and if you are using all HDD slots drives can overheat due to bad airflow (front panel is solid - not vented - for some reason!)
