Specifications

Understanding Displayed vs. Nominal Capacity

Flash memory manufacturers calculate capacity using decimal arithmetic (1 GB = 1,000 MB), while operating systems use binary arithmetic (1 GB = 1,024 MB). This means your drive's displayed capacity will be slightly less than its labeled size — this is normal and applies to all flash storage products. Approximate usable capacities:

• 4GB ≈ 3.6–3.8 GB
• 8GB ≈ 7.4–7.6 GB
• 16GB ≈ 14.4–14.8 GB
• 32GB ≈ 28.5–30 GB
• 64GB ≈ 58.5–60 GB

Usage Tips

1. Always safely eject the drive before unplugging to prevent data loss.
2. Do not remove the drive while data is being transferred.
3. Keep away from extreme heat, moisture, and magnetic fields for best longevity.

Q: What does "waterproof" mean for these drives — can I submerge them in water?

A: The waterproof metal casing is designed to resist everyday splashes and moisture exposure. It is not intended for full submersion. Always make sure the drive is fully dry before connecting it to any device.

Q: Why does my computer show less storage space than the labeled capacity?
