Capacity Reference Guide
Due to differences between computer and drive capacity calculation standards (computers use 1GB = 1024MB; drives use 1GB = 1000MB), the displayed usable space will be slightly lower than the labeled capacity. Approximate usable capacities are:
- 4GB → 3.6GB – 3.8GB usable
- 8GB → 7.40GB – 7.55GB usable
- 16GB → 14.6GB – 15.1GB usable
- 32GB → 28.9GB – 30.5GB usable
- 64GB → 58.0GB – 60.0GB usable
- 128GB → 118.5GB – 120.9GB usable
Note: Actual transfer speed may vary depending on your computer's USB port and system configuration.

Frequently Asked Questions
Q: What does "semi-finished" mean for these USB flash drive PCBs?
A: "Semi-finished" means you receive the bare PCB circuit board with flash memory chips already soldered on, without a plastic or metal outer casing/shell. These are designed for OEM assembly, custom branding, or wholesale resellers who will add their own housing. The drive is fully functional electronically and can be tested as-is with a USB 3.0 port.
Q: Are these USB 3.0 PCB flash drives compatible with USB 2.0 ports?
A: Yes. USB 3.0 is backward compatible with USB 2.0 ports. When used in a USB 2.0 port, data transfer speeds will be limited to USB 2.0 standards. For maximum performance (10MB/s+), use with a USB 3.0 port.
Q: Can I order multiple capacities in a single wholesale batch?
A: These semi-finished USB 3.0 PCB flash drives are available in 4GB, 8GB, 16GB, 32GB, 64GB, and 128GB. For mixed-capacity wholesale orders, please contact us directly to discuss bulk pricing and customization options.
Q: Why does my computer show less storage than the labeled capacity?
A: This is a standard industry difference in how capacity is calculated. The drive uses 1GB = 1,000MB, while your operating system calculates 1GB = 1,024MB, resulting in a slightly lower displayed figure. All units ship with genuine, full-rated chips — the capacity is not reduced.
