I Bought $5 2TB USB Sticks from AliExpress: It's a Scam

A hands-on investigation of ultra cheap 2TB USB sticks purchased from AliExpress reveals they are fake. The drives report 2TB of storage but only hold 32GB before files become corrupted. This article explains what was found and offers advice on how to avoid the same scam.

Introduction

When a 2TB USB stick costs less than a cup of coffee, something is wrong. That was the starting point for this hands-on test. I ordered several $5 2TB USB sticks from AliExpress to see if they were real. What I found was a textbook example of a counterfeit storage scam.

Testing the Drives

After the drives arrived, I connected them to a computer to check their reported capacity. Each stick showed 2TB of available space. However, as soon as I started copying files, problems appeared. The drives accepted data until around 32GB. After that point, files became corrupted and unreadable. The drives were not actually 2TB. They were small capacity drives, likely 32GB, that had been hacked to lie about their size.

The Scam Explained

This type of fraud is common with cheap flash storage. The controller chip inside the drive is reprogrammed to report a fake capacity to the operating system. The actual memory chip is much smaller. When you copy more data than the real capacity, the drive either overwrites existing files or returns errors. In many cases, you will not notice the corruption until you try to open the files later.

Warning and Protection

The investigation includes a clear warning: do not buy these products. The drives are a waste of money and put your data at risk. If you are shopping for USB sticks or external drives, be suspicious of prices that are far below normal market rates. A real 2TB USB stick costs significantly more than $5. Before trusting any new drive, test it with a capacity verification tool. Programs like H2testw for Windows or F3 for Linux can write data to the entire drive and check for corruption. If the test fails, return the drive and report the seller.

Conclusion

The $5 2TB USB sticks from AliExpress are a scam. They claim 2TB but only hold about 32GB before files get corrupted. The testing documented the issue with screenshots and a short video. My advice is simple: do not buy these fake drives. Always verify storage devices before relying on them.
