Can you recommend some devices? Most of the ones i saw had good prices, but not performance relative to power usage. The N100 with its 4 efficiency cores is actually quite good for the price and power usage. Unfortunately most mini pcs with it have limited ports.
I also think, that 2 ssds might be sufficient for the beginning. I’m even thinking of just adding 2 external ssd’s and call it a day for the beginning (one as backup), but that does not scale well.
