Yea this is the main issue we are still trying to figure out with the full node (other than the memory limitations we are still working through). We still want to make it that the whole node runs on the current hardware with nothing extra, but based on how bad the node wears down SD cards we might need to provide an external USB drive solution for better reliability.
Almost done with getting Batch 2 out the door, and my full attention will turn to this...
you've mentioned how reformatting/re-imaging the SD card fixes problems but I don't know if its the SD cards I bought (amazon) but I've never had an issue where I thought I needed to re-image the card. Do you think its something worth doing every once in a while as preventative? Is there any value to it, efficiency, etc...?
