Capacity Guide

Flash memory manufacturers calculate capacity using decimal arithmetic (1GB = 1,000,000,000 bytes), while operating systems use binary arithmetic (1 GB = 1,073,741,824 bytes). As a result, the displayed capacity on your device may appear slightly lower than the labeled capacity — this is completely normal.

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