Storage Upgrade V

The Storage Upgrade (V) is an item added by Storage Drawers. It increases the maximum storage of a Drawer by 32 times its base value. For instance, with only one installed it will increase the maximum storage to 1024 stacks from 32.

Trivia
You do not have to use previous tiers for this to work. You can have the Tier V without the Tier IV.

The storage increase will stack if you install multiple Storage Upgrades.
