Storage Drawers Capacity & Upgrades

A vanilla drawer holds 32 stacks per slot (about 2,048 items for a stackable). Capacity scales up sharply with upgrades:

• Storage Upgrade I — ×2 (64 stacks)
• Storage Upgrade II — ×4
• Storage Upgrade III — ×8
• Storage Upgrade IV — ×16
• Storage Upgrade V — ×32

Upgrades stack: install five Upgrade V chips and a drawer holds millions of items in a single slot. Insert an upgrade by right-clicking the drawer with the upgrade in hand. A small chip indicator appears in the corner of the drawer face.

Other upgrades change drawer behaviour:

• Void Upgrade — overflow items are deleted instead of refusing to insert. Good for cobblestone in a quarry; bad for diamonds.
• Locking Upgrade — locks the slot binding so it cannot be cleared by emptying. Combine with the Drawer Key to toggle locks across many drawers at once.
• Fill Indicator Upgrade — shows a visible fill-level bar across the drawer face.
• Creative Upgrades — Creative Vending (infinite source) and Creative Storage (infinite sink). Survival players ignore; map builders use heavily.
• Conversion Upgrade — extend compacting behaviour to a regular drawer.
