is there anyone that runs bitcoin core on an SD card?
id be surprised if it could get through IBD

full node is obviously not possible maybe a pruned node but the point is the entry barrier is really low.
its not the storage requirement thats the problem with using an SD card
it's the sustained read/write during initial block download(which pruned nodes still have to complete) most SD card readers use controllers which arent suitable for that as they are mostly designed around phones or cameras for lower end devices
