Protects metal from overflow.
Raises the metal cap so production does not overflow while you save.
Full storage wastes real time. Metal storage is quiet until it saves hours of production.
Supports expensive buildings, large ship batches and longer offline windows.
Building time depends on the planet’s Robotics Factory and Nanite Factory levels and on the universe speed, so it is not a fixed number.
Each level multiplies the previous cost by ×2, so each further level gets steadily more expensive the further you push it.

None — available from the start, with no research or building gate.
The four races share the same building rules but not the same hardware — each one names and renders it differently, and applies its own combat multipliers from its race profile.
