Specifications

Capacity & Formatting Guide

Due to differences in how manufacturers and operating systems calculate storage (decimal vs. binary), the usable capacity displayed on your device will be slightly lower than the labelled size. This is normal for all flash memory products.

• 32GB ≈ 27GB–31GB (Format: FAT32)
• 64GB ≈ 58GB–62GB (Format: exFAT)
• 128GB ≈ 95GB–122GB (Format: exFAT)

Important Before Purchasing

Please confirm your device supports the capacity you intend to purchase. Inserting a card that exceeds your device's maximum supported capacity may prevent it from functioning properly — this is a device limitation, not a product defect.

Frequently Asked Questions

Q: Is the OSMR Micro SD card compatible with Android smartphones and 4K cameras?

A: Yes! The OSMR Micro SD card is rated Class 10, U3, V30, and A2, making it fully compatible with Android smartphones, 4K action cameras, dashcams, drones, and most devices with a Micro SD or TF card slot. Always verify that your specific device supports the selected capacity before purchasing.

Q: Why does my device show less storage than the labelled capacity (e.g. 128GB)?

A: This is completely normal. Memory manufacturers calculate capacity using a decimal system (1GB = 1,000,000,000 bytes), while your device's operating system uses a binary system (1GB = 1,073,741,824 bytes). This results in a slightly lower number displayed on your device. There is no defect — all flash storage products work this way.

Q: What format should I use for the 64GB and 128GB cards?

A: For 32GB cards, format using FAT32. For 64GB and 128GB cards, use exFAT for best compatibility and performance. Most modern devices will handle exFAT automatically, but you can also reformat via your computer if needed.

Q: Can I test this card to verify its genuine capacity and speed?

A: Yes. The OSMR Micro SD card supports "H2testw" software testing, which verifies the actual usable storage capacity and write integrity. For accurate speed testing, use a USB 3.0 or higher card reader, as slower interfaces will limit the measured read/write speeds.
