Drive-In systems are designed to provide many years of safe storage in high frequency loading service.  They offer the ability to store a large amount of similar SKUs in a small storage area.  Selectivity is sacrificed, but storage density is outstanding.

In a drive-in system, a lift truck drives into the rack to access pallets two or more deep for pallet placement in a back to front arrangement, and it is ideally suited for First-in, Last-out (FILO) inventory arrangement.  Drive-In racks are typically subject to more abuse than selective racks (due to the way they are utilized), so rack integrity and strength are important factors.

Advantages:

• High storage density for certain product mixes
• Low capital investment vs. other high density options
• Very efficient storage (ability to store pallets back-to-back without aisles)

Limitations:

• Inflexible, does not allow for SKU increase
• Possible low storage utilization (typically 50% of positions used)
• Low productivity (30% slower than alternative systems)
