About Displayed Capacity

Flash memory manufacturers use decimal calculations (1 GB = 1,000 MB), while operating systems use binary calculations (1 GB = 1,024 MB). As a result, the capacity shown on your computer will be slightly lower than the labeled capacity. This is normal and consistent across all flash storage devices:

• 8GB ≈ 7.4 GB – 7.6 GB displayed
• 16GB ≈ 14.4 GB – 15.8 GB displayed
• 32GB ≈ 28.5 GB – 30 GB displayed
• 64GB ≈ 57 GB – 60 GB displayed
• 128GB ≈ 110 GB – 120 GB displayed

Usage Tips

1. Always use the "Safely Remove Hardware" option before unplugging to prevent data loss.
2. Do not unplug the drive during an active file transfer.
3. Avoid formatting the drive unnecessarily to extend its lifespan.
4. Remove the drive from the port when not in use to preserve the connector and data integrity.

Frequently Asked Questions

Q: Are these USB 3.0 flash drives compatible with older USB 2.0 ports?

A: Yes! These USB 3.0 metal flash drives are fully backwards compatible with USB 2.0 and USB 1.1 ports. When used in a USB 2.0 port, transfer speeds will be limited to USB 2.0 standards, but the drives will function normally on any device with a standard USB-A port.

Q: Can I get a custom logo printed on these USB flash drives?

A: Yes, free custom logo printing is available on these drives, making them an excellent choice for branded corporate events, promotional giveaways, trade shows, and school or business use.

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

A: This is completely normal for all flash storage devices. Manufacturers measure capacity using decimal math (1 GB = 1,000 MB), while your operating system uses binary math (1 GB = 1,024 MB). This difference accounts for the slightly lower number shown on your computer — the drives are genuine full-capacity units.

Q: Are these drives suitable for bulk data distribution at events or schools?

A: Absolutely. The 50-pack bulk format is specifically designed for businesses, educational institutions, event organizers, and promoters who need reliable, cost-effective USB flash drives in quantity. The rotatable metal design also makes them durable enough for repeated use.
