I farmed over 60 of these in a matter of hours, mostly running Proteus on Neptune (infested defense). My most successful run yielded 9 in 10 waves mostly breaking the containers. Though I got at least 3 per run, got ton of ferrite as well. I'm not sure if its the best source but I think it worked out pretty well. If anyone else decides to try it out tell me how it goes.
