The best microSD cards for an Android mobile

Android mobile devices are increasingly counting on better internal storage that makes it less and less necessary to have a microSD card as a complementary card. However, there are still many manufacturers who are committed to integrating a slot in which we can insert these cards to improve both the space and the performance of the phone by not overfilling the internal memory of the terminal.

For this reason, we have become more demanding than ever when deciding to buy an external memory that meets our expectations. In addition, it will be a very good alternative in case we want to store all our data and documents in an external space in case our mobile device breaks or we decide to change, since, on many occasions, the space that the cloud offers us remains a little fair.

Types of microSD card for mobile

And it is that, it will not always be easy to choose a type of card for our mobile device . In addition to the fact that it will be necessary to know its most relevant characteristics, and other factors such as its price, its speed and even its compatibility will also have to be taken into account, if it is necessary to know it. Therefore, we will explain how we can choose a card and what we will have to look at. Likewise, we will give you some options that will be striking so that you can insert them into the slot of your smartphone.

MicroSD para móviles

Among the different types we find three types: SD, SDHC and SDXC . However, the only difference that can be found between these cards is that each of them has a different maximum storage capacity. That is, it will depend on the amount of GB that we will count to be able to save our documents and multimedia files. For example, the most current smartphones use the SDXC type, mainly because they have the highest capacity, reaching up to 2 TB.

Although we must bear in mind that the maximum amount must be compatible with the model of our mobile device, since the manufacturer always imposes a maximum that we can establish thanks to introducing this type of card for storage. Therefore, it will be necessary to make sure by looking at the specifications of the mobile device that we have in our possession.

Does the speed and class of a microSD matter?

In addition to the compatibility and the type of external memory that we could use in our Android mobile , we have to know both the minimum speed that it will guarantee and its class. To do this, we will have to look at the UHS classification. Likewise, to determine the minimum writing speed that the SD can have, it is expressed in MB / s. Therefore, we find the following speeds :

  • Class 2: MB / s
  • Class 4: MB / s.
  • Class 6: 6 MB / s.
  • Class 8: 8 MB / s
  • Class 10: 10 MB / s.


However, the latest more modern memory cards, such as SDHC and SDXC , appeared on the SD market with a new class called UHC, which takes advantage of the new data bus in order to achieve higher read speeds. and writing. At present, we can find different classes with their respective maximum and minimum speeds, which are the following:

  • UHS-1 UI 1: minimum speed 10 MB / s and maximum 104 MB / s.
  • UHS-I U3: minimum speed 30 MB / s and maximum 104 MB / s.
  • UHS-II U1: minimum speed 10 MB / s and maximum 312 MB / s.
  • UHS-II U3: minimum speed 10 MB / s and maximum 312 MB / s.
  • UHS-III: up to 624MB / s.
