Capacity Transparency Notice
Flash memory manufacturers calculate capacity using decimal arithmetic (1GB = 1,000MB), while operating systems use binary arithmetic (1GB = 1,024MB). This standard industry difference means the usable capacity displayed on your device will be slightly lower than the labeled size. Approximate usable capacities:
- 2GB ≈ 1.5GB – 1.86GB
- 4GB ≈ 3.5GB – 3.75GB
- 8GB ≈ 7GB – 7.45GB
- 16GB ≈ 14GB – 14.9GB
- 32GB ≈ 28GB – 29GB
- 64GB ≈ 58GB – 59GB
- 128GB ≈ 95GB – 119GB
- 256GB ≈ 230GB – 238GB
Important Compatibility Tip
Before purchasing, please verify that your device supports the capacity you are selecting. If your device only supports cards up to a certain size (e.g. 4GB), inserting a higher-capacity card (e.g. 32GB) may cause the card to not function correctly on that device. This is a device compatibility consideration, not a product defect.
