Raspberry Pi / Rock Pi Micro SD

[ivanbbctba]

Anyone knows the minimum size needed of the Micro SD for the Raspberry Pi / Rock Pi?

I ask this because I supose the Micro SD is where is created the temporary files to be moved to the HDD right? So it should be a 128gb Micro sd or bigger?

No, your understanding is completely wrong.
Raspberry Pi is only for farming. Storing plots and plotting should be in the other machine.
Your Pi just connects the drive array or connects the NFS via network to access the plots on the drive array.
Pi is not strong enough to run a full node. It can only run harvester and you need to connect with a node.
Read more carefully and try to understand the whole structure before you working on actual mining.
