How did we choose these best microSD cards?

In my search, I considered several factors that can also help you:

  • 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.
