So, what exactly is a high endurance microSD card? It's a type of storage that is optimized for thousands of hours of recording. While it will work great in your phone, tablet, or Nintendo Switch, it's ideal for use in an action cam or home monitoring system where data is constantly being written and re-written.

These new High Endurance cards are rated class 10, U3 and v30, adding support for 4K UHD recording, and are capable of withstanding up to 20,000 hours of video without worrying about the card letting you down — up from the previous version's 10,000-hour maximum. That's especially useful for the sorts of devices these cards are built for where you may need to rely on footage captured down the line. The updated model adds 128GB and 256GB options to a lineup previously restricted to just 64GB, meaning more room for the higher-quality video our devices are outputting these days, and the cards are also temperature-proof, waterproof, shockproof and X-ray-proof for extra peace of mind.

Of course, there's a ton of choice in the microSD space and we've got a handy guide to the best microSD cards to help you out. If you're looking specifically for a microSD card to work with your Nintendo Switch, we've got you covered there too.
