Manufacturer description

The TEAMGROUP HIGH Endurance 256GB microSDXC 3-Pack is built for devices that record around the clock, such as security cameras and other monitoring systems. You get three 256GB UHS-I U3 cards in one box, so you can set up several cameras at once or keep spares ready for swaps. Each card carries a V30 video speed class. That means it can sustain 4K Ultra HD and Full HD recording without the slowdowns and dropped frames that cause gaps in footage. Rated read and write speeds reach up to 100MB/s and 50MB/s, which is enough for continuous video capture and for pulling clips off the card when…
