Minecraft wiki entry for Hopper, associated text: The connected design should be used when it is necessary to take items from a single output. Any items stored in this silo will funnel down as the bottom chest is emptied. Since the chests are not all easily accessible, this is more helpful in automation rather than use by the player. However, if it is not necessary to remove a large number of items, it could work. Silos like this are commonly used to hold fuel, minecarts, and shulker boxes.
