Built for action cameras and Android devices

The SanDisk Extreme microSDXC card targets Android smartphones, tablets, action cameras and drones. Its UHS-I interface and A2 rating deliver quick app launches and smooth 4K UHD video capture. The bundled SD adapter lets you read the card in standard slots. Rugged construction survives temperature extremes, water, shock and X-rays.

UHS-I U3 V30 A2 speed ratings decide fit

This card carries UHS Speed Class 3, Video Speed Class 30 and App Performance Class 2. Those marks guarantee a minimum 30MB/s sustained write for 4K recording and fast random I/O for Android apps. Devices that require UHS-II or higher sustained throughput will not benefit from their full potential with this card.

64GB capacity suits heavy 4K sessions

Sixty-four gigabytes holds hours of 4K UHD footage and thousands of high-resolution photos. Read speeds reach 160MB/s and write speeds hit 60MB/s, so offloads and burst shooting stay quick. Extended 8K recording or multi-camera VR rigs will exhaust space and write bandwidth quickly.
