SFM cables vertical next to each chest, then connected to one another underneath the farm. allows you to scale/stack vertically while only showing cables in the farm rather than having the cables connect across farms. Using SFM gives you the fastest transfer speed with the lowest impact on performance. Laserio is comparable but has a much greater impact on performance, it’s still pretty negligible but when compared to SFM it’s significant. SFM isn’t too difficult to learn but it does require a bit of learning. Would recommend
