Are you constantly hitting that frustrating 8,000 storage limit in Arknights: Endfield? Does your production grind to a halt just when your factory is running perfectly? You’re not alone! Every serious Endministrator eventually faces this bottleneck, but here’s the good news: you can expand your storage capacity all the way to 14,000 units through the Depot Node system.

Having spent countless hours optimizing my own base and testing every storage method available, I’ll walk you through the complete process of expanding your storage capacity. This guide covers everything from unlocking your first Depot Node to mastering Valley Stock Bills farming, ensuring your factory never stops running again.

Why Storage Expansion is Essential in 2026?

Before diving into the how-to, let me explain why expanding your storage isn’t just a luxury—it’s absolutely critical for progression:

  • Auto-farming stops completely when storage hits 8,000
  • Mining operations halt mid-cycle, wasting valuable resources
  • Production chains break down causing cascading inefficiencies
  • Late-game material crafting becomes impossible without expanded capacity
  • Valuable time and resources are wasted constantly managing full storage

Trust me, I learned this the hard way after losing hours of progress to full storage. The sooner you upgrade, the smoother your entire factory system becomes.

Prerequisites for Storage Expansion

Before you can expand your storage capacity, several requirements must be met. Missing even one of these will prevent the upgrade option from appearing:

Core Requirements Checklist

Unlock Originium Science Park – Complete main story progression
Finish Ivonne’s Story Mission – Complete the main questline in this area
Reach Level 15 – Required for Stock Redistribution access
Collect Valley Stock Bills – Primary currency for upgrades
Complete Depot Node I Quest – Found in Quest Log → Important section

Story Progression Requirements

The storage system is intentionally gated behind story progression to ensure players understand basic factory mechanics before accessing advanced features. You’ll typically reach these requirements around Chapter 3-4 of the main story, depending on your playstyle.

Advanced Storage Management Strategies

Backpack vs Depot Storage

Understanding the difference between storage types is crucial:

Backpack Storage (35 items):

  • Personal inventory carried by your character
  • Accessed anywhere in the world
  • Use Quick Stash at TP Points to transfer to depot
  • Cannot be expanded beyond 35 slots

Depot Storage:

  • Regional base storage (8,000-14,000+ capacity)
  • Accessible only in specific regions
  • Expandable through Depot Node upgrades
  • Essential for factory operations

Quick Stash Usage

To manage backpack overflow:

  1. Find TP Point (Tale-Protocol Point)
  2. Open Protosync → Maps
  3. Teleport to nearest TP Point
  4. Select “Manage Depot”
  5. Click “Quick Stash” to transfer all materials
  6. Use filters for selective transfers

Factory Integration

Optimize your factory layout with expanded storage:

  • Place production lines near upgraded Depot Nodes
  • Balance input/output rates with storage capacity
  • Use regional transfers between different areas
  • Monitor storage levels to prevent production stops
