MicroSD cards are useful in so many different ways, though finding deals on microSD cards isn't always easy when it's not Black Friday or Cyber Monday. Whether you need more space to store files and music on your phone or if you're setting up a dash cam for HD recording, there are countless ways to put a microSD card to good use though it's important to ensure you're using the right microSD card for each scenario. Of course, they vary in capacity with options from 8GB up to 1TB, though there are several other features you'll want to keep in mind while shopping around.
You'll find that microSD cards have different ratings to assist in comparing them to others, and this is pretty important when it comes to using a microSD card in certain devices like action cameras or the Nintendo Switch. For instance, Video Speed Class 30 means the microSD card is suitable to record and store 4K UHD and Full HD video, while Class 10 rated cards are more suitable for HD video rather than 4K. Better ratings also tend to correspond to higher read/write speeds so you can save and transfer files faster. However, better ratings also happen to correspond to higher prices. Luckily, we've created the guide below to help you find the best microSD card deals so you can save like a pro.
