Understanding Displayed Capacity

Flash drive manufacturers use decimal measurement (1GB = 1,000MB), while operating systems use binary measurement (1GB = 1,024MB). This means your device may show slightly less than the labeled capacity — this is completely normal and not a defect. Here's what to expect:

• 512MB ≈ 470MB–500MB displayed
• 1GB ≈ 950MB–980MB displayed
• 2GB ≈ 1.7GB–1.9GB displayed
• 4GB ≈ 3.6GB–3.8GB displayed
• 8GB ≈ 7.4GB–7.6GB displayed
• 16GB ≈ 14GB–15GB displayed
• 32GB ≈ 28GB–30GB displayed
• 64GB ≈ 58GB–60GB displayed

Frequently Asked Questions

Q: What logo file formats are accepted for the free custom logo printing?

A: You can submit your logo in CDR, AI, PSD, JPG, PNG, or PDF format. The file should be clear and high-resolution, with a maximum upload size of 5MB. Simply send your file to the seller after completing your payment.

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

A: Yes! These USB 2.0 memory sticks are plug-and-play compatible with Windows PCs, MacBooks, and most laptops or notebooks that feature a standard USB port — no additional drivers needed.

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

A: This is a standard industry difference. Manufacturers calculate storage using decimal (1GB = 1,000MB), while operating systems use binary (1GB = 1,024MB). The small discrepancy is normal and your USB flash drive has genuine, full-rated capacity — not a fake or counterfeit product.

Q: Can I order different capacities within the same 20-piece lot?

A: Each lot is typically ordered in a single selected capacity. Please review the available capacity options in the product listing and contact the seller if you have specific mixed-capacity requirements for your bulk order.
