When shopping for a microSD card, just like when looking for a regular SD card, speed and available capacity are the most important factors you need to consider. If you have a high-end smartphone that can capture 4K video, an action camera, or a drone, you need to consider spending a bit more for a capable microSD card.
High-end microSD cards are also generally recommended for smartphones that run (or soon will run) Google's latest Android Nougat operating system. The OS allows users to install apps on external memory, so a speedier microSD card will most likely result in better performance. Also, Nintendo's latest console, the Nintendo Switch, only offers 32 GB of storage, so you'll definitely need extra space for all the best Switch games.
