Mekanism: Mass Storage
by sethpecl
Mass Storage adds four tiers of high-capacity storage machines to Mekanism, from Basic up to the top tier, for players in the late game.
What it does
Each tier is a multiblock storage unit with more slots and more FE energy storage: 1,200 slots and 4,000,000 FE at Basic, 2,400 and 8,000,000 at Advanced, 4,800 and 16,000,000 at Elite, and 19,200 slots and 64,000,000 FE at the top tier. Units take item input and output and FE input and output, with configurable sides and support for Mekanism's Configurator. The mod depends on Mekanism, and Mass Storage is published for NeoForge on 1.21.1 only, with 1.3.0 as the latest file.
Stored items and energy are kept when a unit is broken and placed again, and the side configuration is preserved too. Units can be upgraded between tiers. Built-in crafting, anvil and smithing tables, item search, several sorting modes, a deposit function and tier-specific glowing machine accents are also included. JEI support shows the custom recipes, which are expensive by design.
Key features
Four storage tiers
Basic, Advanced, Elite and the top tier step up in slots and FE capacity, so each tier scales the one before it.
Built-in crafting and smithing
Units include a crafting table, an anvil and a smithing table, so players can craft from the stored items directly.
Search and sorting
Item search, several sorting modes and a deposit function make large inventories easier to navigate.
Expensive, progression-based recipes
The Basic unit calls for large stocks of common materials and Mekanism Steel Casings, and higher tiers need more costly Mekanism components.

Use cases
End-game industrial projects
The top-tier unit is meant as a large industrial project, not a quick early-game replacement for ordinary storage.
Who it’s for: Players who already run Mekanism machines and want storage that matches late-game production. Server owners can add it to a modpack where the progression is planned around Mekanism.
