Usable Capacity Guide
Storage devices calculate capacity slightly differently than computers (1GB = 1,000MB on the card vs. 1GB = 1,024MB on a PC), so displayed usable space will be slightly less than the labeled size. This is completely normal and applies to all memory cards industry-wide:
- 16GB ≈ 14–15 GB usable
- 32GB ≈ 28–30 GB usable
- 64GB ≈ 58–60 GB usable
- 128GB ≈ 115–119 GB usable
- 256GB ≈ 230–238 GB usable
Wide Device Compatibility
These MicroSD cards work seamlessly with virtually any device that accepts a TF/MicroSD slot, including:

Frequently Asked Questions
Q: Are these TF/MicroSD memory cards genuine full-capacity cards?
A: Yes. Ceamere guarantees true-labeled capacity on every card in this 10-pack. All cards can be verified using the H2testw tool on a PC with a USB 3.0 card reader. If any card is found to have misrepresented capacity, a full refund is provided.
Q: What speed class do I need for 4K video recording or dash cam use?
A: For 4K video, dashcam, or professional camera recording, choose the Class 10 U3 variant (available in 32GB and above). It offers read speeds up to 90 MB/s and write speeds up to 45 MB/s, ensuring smooth, uninterrupted high-resolution recording.
Q: Can these MicroSD cards be used with an adapter in a full-size SD slot?
A: Yes. These TF (MicroSD) cards are fully compatible with standard MicroSD-to-SD adapters, allowing them to be used in cameras, laptops, and other devices with a full-size SD card slot. Adapters may be sold separately.
Q: Why does the usable storage show less than the labeled capacity?
A: This is a standard industry difference in how storage capacity is calculated. Card manufacturers define 1GB as 1,000MB, while computers use 1GB = 1,024MB. Additionally, a small portion of space is reserved for the card's internal formatting. This applies to all flash storage products across all brands.
