Recently I updated my NKN mining Raspberry Pi 4 (4GB version) from MicroSD boot to external SSD boot.
- Why? It is supposed to give me much higher read/write speed, and NKN node software need to read and write a lot for keeping in sync with the latest blocks and transactions.
- The result? More than 7 times faster (8250 versus 1133)!
- Does it matter to mining yield? Most likely not, or at least too early to tell. I’m in for the tech.
