• 128MB ≈ 115–125 MB usable
• 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

Perfect For

Frequently Asked Questions

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

A: Simply send your logo file (JPG, JPEG, GIF, PNG, or BMP format, maximum 5MB) through the Seller Customer Service Chat before completing your payment. Once received, your logo will be laser-engraved onto every drive in your order at no extra charge. If you do not send the logo before payment, your order will be shipped within 12 hours without any engraving.

Q: Why does the usable storage capacity shown on my computer differ from the labeled capacity?

A: This is normal for all flash drives. Flash memory manufacturers measure capacity in decimal (1 GB = 1,000 MB), while operating systems calculate in binary (1 GB = 1,024 MB). As a result, a 64GB drive will show approximately 58–60 GB of usable space on your computer. Every drive in this bulk pack is H2testw tested to confirm genuine, full-rated capacity.

Q: What storage capacities are available for these 100-pack metal USB 2.0 flash drives?

A: These bulk USB flash drives are available in multiple storage sizes including 128MB, 4GB, 8GB, 16GB, 32GB, 64GB, and 128GB. Choose the capacity that best suits your use case — from lightweight document sharing to storing large photo or video files for wedding photography and corporate presentations.

Q: Are these USB flash drives compatible with Mac computers and modern operating systems?

A: These drives are confirmed compatible with Windows 98/ME/2000/XP/Vista/7/8. As standard USB 2.0 mass-storage devices, they are also broadly compatible with macOS and newer versions of Windows. No driver installation is required — simply plug in and use immediately.
