Actual Usable Capacity Guide

Due to differences between manufacturer and OS storage calculation standards (1GB = 1,000MB vs. 1GB = 1,024MB), displayed capacity on your computer will appear slightly lower than the labeled size. Here is what to expect:

• 4GB ≈ 3.6–3.8 GB usable
• 8GB ≈ 7.4–7.6 GB usable
• 16GB ≈ 14–15 GB usable
• 32GB ≈ 28–30 GB usable
• 64GB ≈ 58–60 GB usable
• 128GB ≈ 110–120 GB usable

Usage Tips

1. Do not disconnect the drive or shut down your computer during a file transfer to avoid data loss.
2. Always safely eject the drive before removing it from a USB port.
3. Remove the drive promptly after use to help extend its storage lifespan.
4. Avoid frequent formatting, as repeated formatting can reduce the drive's longevity.
