High-endurance microSDXC for continuous recording

The SanDisk MAX ENDURANCE 256GB card is built for devices that write video around the clock, such as home security cameras and dash cams. It carries C10, U3 and V30 speed ratings to sustain Full HD and 4K capture without dropped frames. The package includes a full-size SD adapter and a lanyard for convenient handling.

Fits standard microSD slots with SD adapter included

The microSDXC form factor slots directly into compatible cameras, recorders and action cams. The bundled SD adapter lets you use the same card in full-size SD readers or laptops for quick offloading. No external power or special drivers are required; the card draws power from the host device.

256GB capacity rated for 120000 hours of recording

At up to 100MB/s read and 40MB/s write, the card transfers large video files efficiently while maintaining the sustained throughput needed for 4K. The 256GB capacity holds extensive footage before looping, and the endurance rating supports continuous overwrite cycles far beyond typical consumer cards.
