Technical Specifications

Capacity Guide

Due to differences in decimal (manufacturer) vs. binary (operating system) calculations, displayed capacity may differ slightly from the label. Actual usable space is approximately:

• 32GB ≈ 27GB–31GB (Format: FAT32)
• 64GB ≈ 58GB–62GB (Format: exFAT)
• 128GB ≈ 95GB–122GB (Format: exFAT)
• 256GB ≈ 210GB–238GB (Format: exFAT)

Important Compatibility Note

Before purchasing, please confirm that your device supports the capacity you are ordering. If your device only supports cards up to a certain size (e.g. 4GB), inserting a higher-capacity card may result in it not functioning — this is a device compatibility issue, not a product defect.
