A recent Armbian kernel upgrade bricked my entire Rock64 cluster (5 cards) and after a week debugging, it seems beyond repair.

I would like to find some ARM-based SBC for self-hosting that’s reliable enough to run for the next five years.

My question for you is reliability and support, rather than specs, as I found Pine64 lacking in support and 4 out of 8 cards failed in the period of two years (one got replaced by warranty).

I have already an x86 cluster, so my interest is for ARM vendors and do not need wifi, gpio, audio, hdmi, etc…

Any experience with Orange Pi or Radxa?
