Storage Capacity Guide

Flash memory manufacturers use decimal calculations (1 GB = 1,000,000,000 bytes), while operating systems use binary calculations. As a result, the usable capacity displayed on your device may be slightly lower than the labeled capacity. Approximate usable capacities are:

• 32GB ≈ 27GB – 31GB (Format: FAT32)
• 64GB ≈ 58GB – 62GB (Format: exFAT)
• 128GB ≈ 95GB – 122GB (Format: exFAT)

Speed Class Specifications (32/64/128GB)

• Class 10 | U3 | A2 | V30
• Read Speed: 40–129 MB/s
• Write Speed: 30–80 MB/s
• Supports 4K recording
• Note: Speed testing requires a USB 3.0+ interface for accurate results

Important Compatibility Note

Before purchasing, please confirm that your device supports the capacity you intend to buy. If your device only supports cards up to a certain size (e.g. 4GB), inserting a higher-capacity card may prevent it from functioning correctly. This is a device compatibility limitation and is not a product defect.
