Frequently Asked Questions

Q: What devices is this Micro SD card compatible with?

A: The MicroDrive Micro TF/SD Card is compatible with a wide range of devices including Android smartphones, tablets, laptops, dashcams, action cameras, security/surveillance cameras, drones, smart speakers, and other digital devices that support a standard Micro SD (TF) card slot.

Q: Why does the usable storage on my device show less than the labeled capacity?

A: This is completely normal. Manufacturers measure storage using decimal arithmetic (1GB = 1,000MB), while your computer or device operating system uses binary arithmetic (1GB = 1,024MB). This results in a small difference between the labeled and displayed capacity. Please refer to the usable capacity reference table above for estimated figures per size.

Q: Is this card suitable for 4K video recording?

A: Yes! With a V30 Video Speed Class rating, this card supports a minimum sustained write speed of 30MB/s, making it well-suited for recording 4K UHD video on compatible cameras, action cameras, and drones.

Q: What does the A1 Application Performance Class mean?

A: The A1 rating means the card meets defined read/write IOPS (input/output operations per second) benchmarks, allowing apps to load and run faster when installed or stored on the card — ideal for Android devices that support adoptable storage.
