About Capacity
Memory manufacturers use decimal arithmetic (1GB = 1,000,000,000 bytes), while operating systems use binary arithmetic (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 completely normal and not a product defect.
- 32GB ≈ 27GB–31GB usable
- 64GB ≈ 58GB–62GB usable
- 128GB ≈ 95GB–122GB usable
- 256GB ≈ 210GB–238GB usable
⚠️ Important – Please Read Before Purchasing
Before buying, confirm that 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 — this is a device compatibility issue and not a product defect.

Frequently Asked Questions
Q: Is the OSMR Micro SD Card compatible with my smartphone or Android device?
A: Yes — the OSMR Micro TF SD Card is widely compatible with most Android smartphones, tablets, and other devices featuring a MicroSD card slot. Always verify that your specific device supports the capacity you are purchasing (e.g. 32GB, 64GB, 128GB, or 256GB) before ordering.
Q: What speed interface do I need to test this card's full read/write performance?
A: To achieve and verify the card's maximum rated speeds (read: up to 129 MB/s; write: up to 80 MB/s), you will need a USB 3.0 or higher card reader/interface. Testing via USB 2.0 will show lower speeds and will not reflect the card's true capabilities.
Q: How should I format the OSMR Micro SD Card?
A: For 32GB cards, format using FAT32. For 64GB, 128GB, and 256GB cards, use exFAT for best compatibility and performance. Most devices will prompt you to format the card when first inserted — simply follow the on-screen instructions or format via your device's storage settings.
Q: Why does my device show less storage than the labeled capacity?
A: This is a standard industry difference between decimal (manufacturer) and binary (operating system) calculation methods. For example, a 128GB card may display approximately 95–122GB on your device. This is completely normal and is not a defect.
