Capacity Note
Memory card manufacturers calculate capacity using decimal notation (1GB = 1,000,000,000 bytes), while device operating systems use binary notation (1GB = 1,073,741,824 bytes). As a result, the usable capacity displayed on your device may appear slightly lower than the labeled capacity — this is completely normal and not a defect.
- 2GB ≈ 1.5GB–1.86GB on device
- 4GB ≈ 3.5GB–3.75GB on device
- 8GB ≈ 7GB–7.45GB on device
- 16GB ≈ 14GB–14.9GB on device
- 32GB ≈ 28GB–29GB on device
- 64GB ≈ 58GB–59GB on device
- 128GB ≈ 95GB–119GB on device
- 256GB ≈ 230GB–238GB on device
Important: Before purchasing, verify that your device supports the capacity you intend to purchase. Inserting a card with a capacity exceeding your device's maximum supported limit may prevent the card from functioning properly — this is a device compatibility issue, not a product defect.
