It is not just cameras that use microSD cards, of course. You pay extra for the branding, of course

Technically, it's just the same as the SD format, with similar capacities and speed ratings, just in a much smaller form. Smaller cameras like action cams use the microSD format, as well as drone, smartphones and tablets. Capable of working with a UHS-II compatible DSLR or camcorder, speeds are up to 3x faster than standard UHS-I SD memory cards This card is also shock and X-ray proof, giving enthusiasts and pros added peace of mind. While the 64GB maximum capacity (the alternative being 32GB) may appear a little modest at first compared with other options here, the performance is anything but, with blisteringly swift read and write times of 285MB/s and 180 MB/s respectively. The Transcend SDXC UHS-II U3 is a belter that delivers whether you're shooting raw files or high resolution video. If you’re shooting raw files you want a card that can handle sequential bursts of the highest quality imagery, as well as a capacity that allows for sufficient storage to avoid having to swap cards every five minutes. If your memory card isn't fast enough, you'll find that it will lag and struggle to accomplish the blisteringly-fast shooting speeds that some of the latest cameras are capable of.

This will not only affect how quickly you can transfer images from the memory card to your computer (or one of the best portable hard drives), but it will also impact the burst mode on your camera.

However, this isn't the only way to judge what memory card is best, as you'll also need a card with fast read and write speeds. A 16GB card might be fine for an afternoon wandering around your local wildlife reserve, but videographers looking to shoot all day could get frustrated with having to constantly swap over cards. One of the most obvious ways to differentiate between memory cards is how much storage they have. However, Compact Flash, microSD and CFast cards are still all regularly used as well. However, if you're using a newer camera, or one of the best professional cameras, then you'll likely need to look for a CFexpress or XQD card. When you think of a memory card, you'll likely find that the popular SD card format comes to mind.
