Odds are you own a bunch of devices that require microSD cards for storage. It's never a bad idea to stock up when they go on sale, especially at times like Cyber Monday when new low prices are hit. It's especially important to pick up a reliable card, like this discounted 256GB SanDisk High Endurance microSD card, if you're using a dash cam or a home security system and need to ensure that your storage won't fail on you at a crucial moment. At $39.99, this dependable card is down to its best-ever price at Amazon. When this card hit the market earlier this year it was going for $60 and the lowest we have seen it go before today was $52.

This has more than enough space for the average consumer, and it works perfectly for things like dash cams and security cameras where data needs to be overwritten regularly. There's no telling how long this discount will last, so stock up now.

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.
