Storage/Picking Comparison
The graph below shows the number of picks per hour compared to the cubic capacity of several material storage systems. Flow racks, for example, allow the highest number of picks per hour, but have the smallest capacity. A two-aisle mini load, however, offers a high number of picks as well as a large storage capacity.

Pick vs. Cube Comparison of Storage Systems and Picking Methods



The table below describes a typical pick rate, cubic storage capacity, and number of SKUs for each type of material storage system:

Storage Medium Picks/Person/Hour Cubic Feet # SKUs

1 Zone of Flow Rack 250 500 100
1 Pod Carousel (3 units) 210 4,500 800 +
2 Aisles of High-Speed Box Buffer 200 12,800 600 +
2 Aisles of Mini Load 180 50,000 Unlimited
90 Bays of Pallet Rack 20 36,000 720 +
2 Aisles of Unit Load 60 157,000 1,500 +
