Capacity & Formatting Guide
Flash memory capacity is measured in decimal (1GB = 1,000,000,000 bytes), while operating systems use binary arithmetic (1GB = 1,073,741,824 bytes). This means the usable capacity displayed on your device will appear slightly less than the labelled size — this is normal and applies to all flash memory products.
- Format as exFAT: 64GB, 128GB, 256GB
- Format as FAT32: 2GB, 4GB, 8GB, 16GB, 32GB
Approximate usable capacity by device:
- 2GB ≈ 1.5–1.9GB
- 4GB ≈ 3.5–3.9GB
- 8GB ≈ 7–7.8GB
- 16GB ≈ 13.5–15GB
- 32GB ≈ 27–31GB
- 64GB ≈ 58–62GB
- 128GB ≈ 95–122GB
⚠️ Important: Check Your Device's Maximum Supported Capacity Before Purchasing
Please verify that your device supports the card capacity you are selecting. Inserting a card that exceeds your device's maximum supported capacity will prevent the card from functioning properly — this is a device compatibility issue, not a product defect. For example, if your device only supports up to 4GB, a 32GB card will not work correctly in it.

Frequently Asked Questions
Q: What devices are compatible with this Micro SD card?
A: This Micro TF SD card is compatible with a wide range of devices including smartphones, tablets, laptops, digital cameras, dashcams, MP3/MP4 players, surveillance cameras, drones (UAVs), robots, smart speakers, and other digital devices that support Micro SD / TF card slots.
Q: Why does the usable storage shown on my device appear less than the labelled capacity?
A: Flash memory manufacturers measure capacity in decimal units (1GB = 1,000,000,000 bytes), while operating systems use binary units (1GB = 1,073,741,824 bytes). This standard industry difference means your device will always display slightly less available space than the printed label — it is not a defect.
Q: What format should I use when formatting my Micro SD card?
A: For cards 64GB and above (64GB, 128GB, 256GB), use exFAT format. For cards 32GB and below (2GB, 4GB, 8GB, 16GB, 32GB), use FAT32 format. Using the correct format ensures full compatibility with your device.
Q: Does the 128GB card support 4K video recording?
A: Yes. The 32GB, 64GB, and 128GB variants are rated C10, U3, A2, V30 and support 4K video with write speeds of 30–80 MB/s and read speeds of 40–129 MB/s. For accurate speed testing, a USB 3.0 or higher interface is required.
