Capacity Note

Flash memory manufacturers calculate capacity using decimal arithmetic (1GB = 1,000,000,000 bytes), while device operating systems use binary arithmetic (1GB = 1,073,741,824 bytes). As a result, the capacity shown on your device may appear slightly lower than the labeled capacity. This is normal and is not a product defect. Approximate usable capacity by label:

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: Before purchasing, please confirm that your device supports the capacity you intend to buy. Using a card with a capacity beyond your device's supported range may prevent the card from functioning correctly on that device. This is a device compatibility issue and is not covered under product quality guarantees.

Frequently Asked Questions

Q: What devices are compatible with the OSMR Micro TF SD Card?

A: The OSMR Micro SD Card is compatible with a wide range of devices including smartphones, tablets, digital cameras, dashcams, drones (UAV), MP3/MP4 players, laptops, digital speakers, robots, and other devices with a Micro TF/SD card slot. Always check your device's maximum supported card capacity before purchasing.

Q: What is the difference between the speed ratings (C6, C10, U1, U3, V10, V30, A2)?

A: These ratings indicate minimum read/write speed guarantees. C10/U3/A2/V30 cards (32GB–256GB) are the fastest and support 4K video recording. C10/U1/V10 cards (8GB–16GB) support Full HD 1080P video. C6/U1 cards (2GB–4GB) are ideal for photos and standard data storage. Match your card to your device's requirements for best performance.

Q: Why does my device show less storage than the card's labeled capacity?

A: This is a standard industry difference in how manufacturers and operating systems calculate storage. Manufacturers use decimal math (1GB = 1,000,000,000 bytes), while your device uses binary math (1GB = 1,073,741,824 bytes). This results in slightly lower displayed capacity — it is completely normal and not a defect.

Q: What format should I use when formatting my Micro SD card?

A: For cards 2GB–32GB, use FAT32 format. For cards 64GB–256GB, use exFAT format. Using the correct file system ensures full compatibility and optimal performance with your device.
