Before choosing

When it may fit

It may suit storage expansion or recording in action cameras, drones, tablets and other devices supporting this capacity and card classes. Check your device’s approved-card list and recording requirements; a 4K label does not guarantee every resolution, frame rate or bitrate. The SD adapter changes the physical form factor without turning the card into an SSD.

Limits

Advertised maximum speeds depend on the reader, host device and test conditions. Reaching 190 MB/s requires compatible technology and a compatible reader; the supplied adapter does not guarantee that speed. A2 performance also depends on host support. Formatted usable capacity is lower than 128GB. We have not physically tested speed, endurance, compatibility or data recovery.

Check before buying

Confirm ASIN, SKU, capacity and the 190/90 MB/s revision in the offer. Check microSDXC support, maximum host capacity, seller, condition, regional warranty, contents, delivery and returns. A USB reader is purchased separately if your device requires one. Keep backups of important files. Check current price and availability on Amazon before buying.
