Storage Cells

Storage Cells, are one of the core mechanics of storage in Applied Energistics 2, there are three kinds: one for items, one for fluids, and one for regions of space.

Item Storage Cells

Item storage cells can hold up to 63 distinct types of items; the number of items they can store depends in part on how many types they're holding, and their storage capacity.

Portable Item Storage

Fluid Storage Cells

Fluid storage cells can hold up to 5 distinct types of fluids; the volume of fluid they can store depends in part on how many types they're holding, and their storage capacity.

Portable Fluid Storage

Capacity Limits

Storage cells have limits of size, and limits of types, plus you need to consider the resource usage of your cells, to decide what your best options are. Each storage cell can store a fixed amount of data. Each type consumes a number of bytes (which varies with the cell size), and each item consumes one bit of storage, so eight items consume one byte, and a full stack of 64 consumes 8 bytes, regardless of how the item would stack outside an ME network. For instance, 64 identical saddles don't take up more space than 64 stone.

Gunning straight for top tier storage cells, is not generally the best idea, since you use more resources, but don't get any extra type storage.

Below is a table comparing the different tiers of storage cells, how much they store, and a rough estimate of their cost.

Spatial Storage

Storage cells for spatial I/O come in three sizes.
