Built for continuous monitoring

The Samsung PRO Endurance 256GB microSDXC card targets dash cams, body cams and security cameras that write video around the clock. It carries Class 10, U3 and V30 ratings to sustain the bitrates those devices demand. The bundled adapter lets it slot into full-size SD readers.

Sustained write performance

Sequential write reaches 40 MB/s and read reaches 100 MB/s, keeping pace with Full HD at 26 Mbps and 4K streams without dropping frames. The 256GB capacity is rated for 140 000 hours of continuous recording, equivalent to more than 16 years of non-stop capture. Speed varies with host device and usage conditions.

Durability and environmental tolerance

The card resists magnetic fields up to 15 000 Gauss, airport X-ray exposure, water immersion, drops and temperature extremes. It uses an exFAT file system formatted with SD Formatter 3.1, and actual usable capacity may be less than the labelled 256GB. A five-year limited warranty covers the card itself.
