Yes that was me. I am playing with this ideas since a year now. Electricity is expensive here and eating up a lot of my payout. But would a smaller system with a lower power consumption still be able to hit the same payout? How many hard drives can I connect to a low power system? That is hard to tell unless someone decides to uploads a shit ton of data in a short amount of time ideally maxing out my available bandwidth…
My current goal is 4-5 20TB drives on a Pi5 with a 1-2 TB SSD for OS and metadata caching. Should be enough for a 250MBit/s line. We will see how that plan works out.
