The storage of mobile phones does not stop growing, at the same time as the video and photo files that we get with the different mobile cameras that we can buy. These increases in size make us be forced in certain situations to buy a MicroSD card to increase its capacity, we will find many memory cards that may seem the same, although they have many differences between them.
So that we know how to recognize them and differentiate them, we are going to explain to you what their main differences consist of , such as the types of MicroSD cards, the classes and speeds, as well as for what purpose each one of them is created. We want you to choose the best option and get your videos, photographs and especially your mobile, go at full speed.

Types of MicroSD mobile cards
We call all memory cards MicroSD cards, although among them there are different names that divide them into three. Each of them has a maximum capacity and characteristics that make them more suitable for what need. Before buying a card for our mobile, we must check what microSD storage it supports, since not all cards and their storage will be valid for your phone.
These cards have a maximum capacity of 2 GB and were common years ago when smartphones did not have the great importance they have today.
The next step was microSDHC cards, an improvement that allows capacities larger than 32 GB with more appropriate results for use with photographs and video.
Finally we find the latest standard, called micro SDXC and that offers us storage of up to 2 TB and the best results will give us on our mobile phone currently.
Classes and speeds of MicroSD cards
Classes could be known as the category of MicroSD cards, which are arranged according to the transmission speed they are able to offer us on our mobile phone. As with the different types of cards, each of them can offer us different results and therefore it is important to know which one will be the best for our phones.
- Class 2: It allows us to obtain a minimum speed of 2 MB / s.
- Class 4: Its minimum reading speed is 4 MB / s.
- Class 6: It has a speed of 6 MB / s.
- Class 10: Its minimum reading speed is 10 MB / s with U1 and V10 certification.
Within the Class 10 cards, we find improvements that allow us to obtain better results depending on the mobile phone where we are interested in using it, as we will know later.
- Class 10 of 30 MB / s: with U3 and V30 certification
- Class 10 of 60 MB / s: with V60 certification
- Class 10 of 90 MB / s: with V90 certification
Appropriate uses for each card
As we have been commenting, each card and class is adapted to some needs, so before choosing which MicroSD card we are going to buy, we must know what the manufacturer of our mobile phone says with its maximum storage capacity and if it makes any indication about the class or allowed speeds.
In case we are interested in storage based on storing photographs, videos or applications, it will be more than enough with a MicroSDXC class 6 card , choosing among countless available capacities. On the other hand, if we are interested in recording video and allowing ourselves to obtain the best photographs, we will have to make the leap to class 10 , where we find different qualities according to their certification.
- Class 10 of 10 MB / s: allows recording in 720p / 1080p / 4K .
- Class 10 of 30 MB / s: allows recording in 1080p / 4K at 60 or 120 FPS .
- Class 10 of 60 MB / s: allows recording in 8K at 60 or 120 FPS .
- Class 10 of 90 MB / s: allows recording in 8K at 60 or 120 FPS .
It is always advisable to buy a MicroSD card that offers us something else, since it is something that we will always be able to change mobile phone and use it for a long time. In the coming years we will see how mobile phones allow us to record in 8K and therefore it seems nothing crazy to buy a MicroSD card with these capabilities.
