The Unit Storage is a storage building which allows for up to 180 pieces of unit product to be stored. It acts as a simple buffer, a delivery and return point for Construction Parts (and their variants) with trucks, and an offloading destination for the Trading Dock, Shipyard, and Unit Modules in Cargo Depots.
They also have 2 input and 2 output connection points for Flat Conveyors and can utilize all 4 simultaneously if so desired. Like many buildings, when the outputs are directly connected to the inputs of another (without conveyors), they transfer items at about 360 / 60 .
