With U3, V30, and A2 speed class certifications, these cards meet the requirements of modern action cameras, drones, and smartphones that rely on high data throughput. Available in capacities from 64GB to 512GB, you can choose the right balance of storage and speed for your workflow.

Features and Construction

The Lexar 1066x cards are built around NAND flash technology and are compatible with standard micro SD slots. They combine high-speed data transfer with reliable operation in varied conditions.

Speed and Class Ratings

All capacities achieve class 10, U3, V30, and A2 performance standards. This means sustained write speeds suitable for 4K video at 30 frames per second, plus optimised random read/write for app performance on compatible devices. The 64GB variant writes at up to 70MB/s, while the 128GB, 256GB, and 512GB versions write at up to 120MB/s.

Size and Practical Fit

At just 11mm x 15mm x 1mm, this card fits into the micro SD slot of most UAVs, action cameras, smartphones, and tablets. Its compact design allows it to remain flush in the slot, reducing the risk of accidental dislodgement during use.

Uses and Placement

This memory card suits a range of high-data devices, from professional drones to everyday mobile phones. The A2 rating is particularly beneficial for app storage.

Drone and Action Camera Use

For UAV and action camera users, the U3 and V30 ratings help prevent recording errors during high-bitrate video capture. The card can store hours of 4K footage without stuttering, making it a practical choice for aerial surveys, event coverage, or travel vlogging.

Everyday Device Storage

In a smartphone or tablet, the A2 rating improves random read and write speeds for app launching and multitasking. This makes the card suitable for expanding internal storage for games, photos, and offline media.
