For a couple of months now, the average I have on my multinode host is ~10GB/day. The days when it goes up more it is because the other node is full and then the ingress is doubled from 10 to 20 GB. I attached the image of the node that has free space.
There will always be uploads that fail, there will be more days, other days less, it all depends on the speed of the other nodes.
Also keep in mind that the more nodes there are, the less income we will have, because the more will be distributed
If you have healthy discs and everything works well, I wouldn’t give it importance.
