What Are the Three Main Types of Storage in a Warehouse?
Here at Warehouse Space we know that choosing the right storage methods is essential for running an efficient, safe and cost-effective warehouse. There are three main types of storage, each one supporting different product profiles and operational needs. Down below, we’ll teach you about the different types of storage.
1. Bulk Storage
Bulk storage is typically used for holding large amounts of the same product, usually stored directly on the floor or in block stacks.
This type of storage is ideal for:
- Palletised goods in high volumes
- Products with low SKU variety
- Fast-moving items that need easy access for loading and dispatch
Bulk storage makes excellent use of space when products can be stacked safely. However, it usually works on a first-in, last-out basis (FILO), so it better suits goods that are not date-sensitive or where rotation is less critical.

2. Racked Storage
Racked storage uses structured racking systems to hold pallets or cartons at multiple levels, increasing vertical capacity and improving organisation.
Common racked solutions include:
- Adjustable pallet racking (APR) - flexible and widely used, allowing direct access to every pallet
- Drive in / drive through racking - maximises density for homogenous products
- Cantilever racking - ideal for long or bulky items such as timber, pipes or sheet materials
Racked storage offers better stock visibility, improved product protection and easier stock rotation. It is particularly suitable where you need a balance between high density and selective access.
3. Shelving and Small Parts Storage
Shelving systems are designed for smaller items, individual cartons and piece-pick operations. They are often used in e-commerce, spare parts, pharmaceuticals and any environment where order picking is frequent.
Typical features include:
- Adjustable shelves for different product sizes
- Clear labelling and segmentation for quick identification
- Compatibility with bins, totes and dividers
Shelving and small parts storage support efficient picking by placing items within easy reach. When combined with good layout planning, they can significantly reduce picking times and errors.
Putting It All Together
Most modern warehouses use a combination of bulk, racked and shelving storage, with the right mix depending on factors such as product dimensions and weights, stock rotation and shelf life, order profiles and picking methods, as well as future growth and flexibility requirements. By understanding the three main types of storage and how they complement each other, you can create a warehouse layout that truly works for your operation.
