Real Capacity Reference

Flash drive capacities are calculated by manufacturers at 1GB = 1,000MB, while your operating system uses binary calculation (1GB = 1,024MB). This means the displayed capacity on your computer will appear slightly less than the labeled size — this is completely normal across all flash storage products.

• 256MB ≈ 230–238 MB usable
• 512MB ≈ 461–476 MB usable
• 1GB ≈ 0.92–0.97 GB usable
• 2GB ≈ 1.7–1.85 GB usable
• 4GB ≈ 3.5–3.7 GB usable
• 8GB ≈ 7.4–7.8 GB usable
• 16GB ≈ 14–15 GB usable
• 32GB ≈ 28–30 GB usable
• 64GB ≈ 58–59 GB usable
• 128GB ≈ 110–120 GB usable

Frequently Asked Questions

Q: How do I submit my custom logo for laser engraving on the USB flash drives?

A: After completing your purchase, send your logo file (JPG, JPEG, GIF, PNG, or BMP format, up to 5MB) via the order chat or message system within 10 hours of payment. Laser engraving is completely free with every bulk order. If you require full-color printing, please contact customer service for pricing details.

Q: Why does the USB flash drive show less storage space than advertised?

A: This is a standard industry difference in how capacity is calculated. Manufacturers measure 1GB as 1,000MB, while computers use the binary standard of 1GB = 1,024MB. This results in a slightly lower displayed figure on your device — it is not a defect. All drives are H2testw tested to confirm real, usable capacity before shipment.

Q: What is the minimum order and how long does shipping take?

A: This listing is for a 100-piece lot. Proofing for custom laser engraving is completed within 1–3 business days. Standard bulk orders are dispatched within 2–5 business days after logo approval or order confirmation. Shipping time will vary by destination.

Q: Are these metal USB drives compatible with Mac and Windows?

A: Yes. These USB 2.0 flash drives are hot plug-and-play and compatible with any device that has a standard USB port, including Windows PCs, MacBooks, and notebooks. No drivers are required.
