SanDisk Extreme 64GB microSDXC Card

The SanDisk Extreme microSDXC card offers 64GB of storage for action cameras, drones and Android devices. Rated U3 with read speeds up to 160MB/s and write speeds up to 90MB/s, it handles 4K video capture and rapid burst shooting. The card is supplied new and ready for immediate use.

Ideal for 4K video and high-speed bursts

Creators recording 4K footage or shooting fast continuous stills will benefit from the sustained write performance. Users who need larger capacities for extended shoots or who require maximum write speeds for professional cinema codecs should consider higher-capacity or faster-tier options.

U3 speed class rating

The U3 rating guarantees a minimum sequential write speed suitable for 4K video recording. This single specification determines whether the card meets the sustained throughput your device demands.
