If you spend a lot of time farming in Arknights: Endfield, you have probably hit the 8,000 storage limit more times than you would like. Resources pile up fast, production suddenly stops, and your base starts feeling inefficient. This issue becomes even more noticeable in mid to late game, especially when auto farming and mining are running nonstop.
The good news is that the storage cap is not fixed. You can increase it beyond 8,000, reaching 11,000 and even 14,000 with the right progression. However, the system is tied to specific features and currencies, so it cannot be done instantly. This guide explains the full process in a clear and step-by-step way.

Why You Need to Upgrade Base Storage
The default 8,000 storage limit fills up very quickly if you:
- Use auto farming frequently
- Continuously mine ores
- Produce mid to endgame materials
- Rarely sell excess resources
Once storage is full, all production stops automatically. This can severely slow down your progress, making storage upgrades essential for long-term base management.
Main Requirements to Upgrade Storage
Before you can increase your storage capacity, several conditions must be met. If even one is missing, the upgrade option will not appear. You must:
- Unlock Originium Science Park
- Complete the main story in that area with Ivonne
- Collect Valley Stock Bills
- Unlock the Depot Node feature through a side quest
These requirements are mandatory, so make sure your story progression is far enough.
How to Unlock the Depot Node
The Depot Node is the core system used to expand storage capacity. Steps to unlock it:
- Open the Quest Log
- Go to the Important section
- Look for a quest called Depot Node I
- Complete the quest
After finishing it, Depot Node II will become available, allowing further upgrades later on.
The Depot Node itself is located in Originium Science Park and appears as a large machine rising from the ground once activated.
How to Upgrade Storage Using the Depot Node
Once the Depot Node is active:
- Interact with the Depot Node machine
- Pay the initial activation cost
- Upgrade it to Level 1
Level 1 Upgrade Effects
- Storage capacity increases by +3,000
- Total storage goes from 8,000 to 11,000
You can continue upgrading after that.
Additional Upgrade
- Another +3,000 storage
- Total capacity reaches 14,000
- Costs around 40,000 Valley Stock Bills
The cost is high, but the benefits are massive for long-term farming and production.
Fast Ways to Get Valley Stock Bills
Since Depot Node upgrades are expensive, farming Valley Stock Bills efficiently is important. The best methods include:
- Selling items through Outpost Management
- Using the Stock Redistribution Center
- Buying Elastic Goods and reselling them at a higher price in a friend’s base
- Doing these trades consistently once per day
This method is considered the most reliable source of Valley Stock Bills in mid game.
New Feature After Upgrade: Pack of Goods Delivery
Upgrading the Depot Node also unlocks Pack of Goods, a delivery-based mini system.
How it works:
- Select a delivery package
- Transport it to a specific location, such as a recycle station
- Make sure the goods are not damaged
- Complete the delivery to earn rewards
One successful delivery can give around 55,000 Valley Stock Bills, which is often enough to cover the initial Depot Node upgrade cost.
Tips to Make Storage Upgrades More Efficient
- Upgrade the Depot Node as early as possible if you farm often
- Avoid letting resources sit at the 8,000 cap
- Combine trading and delivery systems for faster Valley Stock Bills
- Higher storage gives much more flexibility for long-term base planning
Increasing storage capacity in Arknights: Endfield is no longer optional for players who want smooth progression. By unlocking the Depot Node and investing Valley Stock Bills, you can raise your storage limit from 8,000 to 11,000, and eventually 14,000.
While the process requires effort and a solid amount of currency, the payoff is worth it. Farming becomes smoother, production runs without interruption, and base management feels far more comfortable. The sooner you upgrade your storage, the better your overall experience will be moving forward.
