One of the characteristics that we must always take into account when buying a new mobile is if it includes the possibility of using a MicroSD card. This solution has been in mobiles for a long time, even before the existence of the first smartphones, although using a memory card may not be as good a decision as we thought as it directly affected the performance of mobiles.
With the arrival of the so-called “cloud”, memory cards are increasingly resigned to second place, although they continue to be a very popular tool, especially in mid-range and entry-level phones . However, the first thing we should know is that among the different mobile memory cards that we can find, not all offer the same performance and we can find notable differences.
Negative points of memory cards
The reasons for using a memory card are very clear, since it is a resource when faced with a need, but nevertheless they do not usually tell us how it negatively affects our mobile phone. Above all, there is a factor that affects and is the performance of our smartphone, which is derived and can affect to a greater or lesser extent according to aspects that we are going to know.
Longer reading times
By using a MicroSD card in our mobile we are adding an extra storage, which is a space that did not exist before and for which the entire system of the mobile has to work. It is not the same as our mobile phone having to search the photos in a single drawer, rather than having to do it in two, to explain it in an expensive and simple way.
The loading times therefore become slower and make us have to wait longer for our mobile to let us see the photos or show them on screen. Although this can be affected in various ways depending on the capacity of the processor, GPU and of course the number of files or use that we give to the memory card.
It will depend on the number of files
If we only have a memory card to save some specific photos that we later want to transfer to the computer, it will not be the same as if we backed up our entire gallery here. The same happens if we use the memory card to save applications , which we do not recommend because we will be giving more value to the card than to the internal memory itself and we will notice large differences in loading time.
The memory card and the performance of the mobile phone have a close relationship that we can make more enjoyable depending on our use. We have the possibility of using it and if we do, we must know that it can have its consequences by not carrying it out in the best way.
Directly related to the type of card
There are many memory cards that we can use on mobiles, as we already mentioned at the beginning of the post, but there are also classes with their respective speeds. If we decide to include a memory card in our mobile, we will have to opt for a Class 10 card, with which we will be able to have transfer speeds of at least 10 MB / s and we will not suffer too long charging times or problems remarkable performance.
When recording videos with the mobile phone, we also found a clear relationship with the types of cards. So that you have no doubts before buying one of them, we show you the great differences in terms of transfer speed in Class 10:
- 10 MB / s class 10: allows recording in 720p / 1080p / 4K .
- 30MB / s Class 10: Allows you to record in 1080p / 4K at 60 or 120 FPS .
- Class 10 60MB / s: Allows you to record in 8K at 60 or 120 FPS .
- 90 MB / s Class 10: Allows you to record in 8K at 60 or 120 FPS .
In the same way that the internal memories of our phone can be UFS 3.1, UFS 3.0 or UFS 2.1 among others, we must give value to the types of cards before buying any if we do not want our mobile to become slow due to the card memory.
