Capacity Note
Flash memory manufacturers calculate capacity using decimal math (1GB = 1,000,000,000 bytes), while operating systems use binary math (1GB = 1,073,741,824 bytes). As a result, the usable capacity shown on your device may appear slightly lower than the labeled capacity. This is an industry-standard difference, not a defect.
- 2GB ≈ 1.5–1.9 GB usable
- 4GB ≈ 3.5–3.9 GB usable
- 8GB ≈ 7–7.8 GB usable
- 16GB ≈ 13.5–15 GB usable
- 32GB ≈ 27–31 GB usable
- 64GB ≈ 58–62 GB usable
- 128GB ≈ 95–122 GB usable
- 256GB ≈ 210–241 GB usable
Recommended Format
- FAT32: 2GB, 4GB, 8GB, 16GB, 32GB
- exFAT: 64GB, 128GB, 256GB
Important Before You Buy
Please confirm your device supports the capacity you are purchasing before ordering. If your device only supports up to a certain capacity (e.g., 4GB), inserting a larger card may not work — this is a device limitation, not a product defect.

Frequently Asked Questions
Q: Is this Micro SD card compatible with my smartphone or Android device?
A: Yes — this Micro TF SD card is compatible with most smartphones, Android tablets, and other devices that accept a standard Micro SD (TF) card slot. Always verify your device's maximum supported capacity before purchasing to ensure full compatibility.
Q: Does this SD card work with security cameras and dashcams?
A: Absolutely. This card is designed for use in security monitoring cameras, dashcams, and similar devices. For continuous 1080P recording, the 8GB or 16GB (C10/U1) variants are recommended. For higher-resolution or extended recording, choose the 32GB–256GB (C10/U3/V30) options.
Q: What format should I use when formatting this Micro SD card?
A: For cards 32GB and under (2GB–32GB), use FAT32 format. For cards 64GB and above (64GB, 128GB, 256GB), use exFAT format. Most devices will prompt you to format on first use, or you can format manually via your computer or device settings.
Q: How do I test the card to make sure it is genuine and fully functional?
A: This card supports H2testw testing software, which verifies that the full labeled capacity is readable and writable. A damaged area of less than 4% is within acceptable tolerance; any red-flagged areas in H2testw typically reflect software compatibility differences rather than physical card defects.
