Capacity & Formatting Guide
Due to differences between decimal (manufacturer) and binary (operating system) calculation methods, the usable capacity displayed on your device may be slightly lower than the labeled size. This is normal and expected across all flash memory products.
- 32GB ≈ approximately 27GB–31GB (Format: FAT32)
- 64GB ≈ approximately 58GB–62GB (Format: exFAT)
- 128GB ≈ approximately 95GB–122GB (Format: exFAT)
⚠ Important Note
Before purchasing, please confirm that your device supports the required capacity. Inserting a card with a capacity beyond your device's supported range may prevent it from functioning properly — this is a device compatibility issue and is not a product defect. Speed testing requires a USB 3.0+ interface for accurate results.
