The Samsung Evo Plus microSD card is the overall best microSD card, thanks to its reliable performance and tough, durable build. This is a well-protected microSD card with four-proof protection; it is waterproof and can stand up to varying temperatures with both an X-ray- and magnet-proof design. It is a Grade 3, Class 10 card that offers reasonable read and write speeds with 4K UHD support for all of your important videos and files. When you use this card, you can transfer a 3GB video in only 38 seconds.  When you have a lot of videos to transfer, consider the Lexar Professional 1066x microSDXC card. With UHS-I technology, transfers are super fast - one of the fastest on our list - with support for Full HD and 4K UHD content. This card is compatible with a series of devices, including your smartphone, tablet, and camera. Use this card with your drone, action camera, or Android smartphone. Either way, it is water-, shock-, vibration-, and X-ray-proof for a reliable build that you can take with you on the go.  The Samsung EVO Select MicroSD Memory card also supports 4K UHD content. It is a Class 10, U3 card that comes with a full-size SD adapter. You can benefit from both SD and microSD compatibility for greater flexibility. It is fast, too. You have the ability to transfer a 3GB video in 38 seconds for ultra-fast transfers, and it is equipped to store all your favorite content, holding up to 20 hours of full HD video or 37,600 photos. The SanDisk Extreme SSD V2 comes in very high capacities, with as much as 4TB of storage. Transfer speeds are slower than the others on our list but its storage helps make up for it. It is twice as fast as its previous model, using NVMe™ solid state technology to store and transfer your files. The portable design brings extra peace of mind with a build that is both IP55 water- and dust-resistant and can withstand a two-meter drop. The SanDisk Extreme Pro MicroSDXC card has the fastest speeds of all the best microSD cards. You have an option of the standard capacities, but this card is an excellent fit for those using smartphones with an A2 rating. SanDisk QuickFlow Technology means 4K UHD video recording and full HD video, plus delivery of those photos in high resolution. If you want even faster speeds, add on the SanDisk Professional PRO-READER SD and microSD™ for an even better experience.

Capacity: If you do have a lot of photos and videos, a smaller microSD card will not be enough to store all your items, so you would want to look for a larger microSD card, like one with 128 GB or even 1 TB if you need it. Speed: Most devices are compatible with a Class 10 or U1-rated card. However, if your device requires a lower speed class, shop for microSD cards that have a Class 2, 4, or 6 classification. Cost: The price of a microSD card is a major consideration because budgets can vary significantly. We look for microSD cards that suit a number of budgets, ensuring that there is something for everyone.
