One of the great advantages of many Android phones over the iPhone is the possibility of increasing storage thanks to micro SD cards. However, in most cases this increase in capacity does not translate into as efficient use as if it were the original volume of the telephone. That is, these microSD cards will never be the same as the serial storage of the mobile.
The micro SD cards have a series of disadvantages that we have to take into account. To begin with, they can be damaged. Not all apps can pass to them and if they do, they could work with some limitations. But if there is a key factor in SD cards, that’s the speed. We need a micro SD card with a data transfer speed similar to the internal memory of the phone. What can we find in the market that meets our needs?
Before launching to buy a microSD card, we recommend that you analyze what you have to look to buy a micro SD card that allows you to make the most of your Android phone, because not only speed, but also capacity, type or price matter.
Speed in microSD cards
When we are clear about what capacity our Android phone allows and what we need, the next step is to choose the speed of the card. It is useless to opt for a medium-sized microSD card if your data transfer speed is very low.
The data transmission speed of the microSD cards is classified by class or Speed Class. It is a number that will determine the minimum write speed in MB / s. That is, the higher it is, the faster it will write.
|MINIMUM WRITE SPEED (MB / S)|
As a general recommendation for both Android phones and cameras or any other device is that you always choose class 10.
In some models we can also find the maximum reading speed, although it tends to refer more to punctual peaks than to continuous behavior.
