You have surely noticed that the price of micro SD cards do not go entirely in line with the Storage capacity . One of the factors that determine its cost is the speed from the same. For this there is a series of enumerations and references that determine and delimit their performance . However, what is the true speed of reading and writing a micro SD card ?
Maybe you wonder … why do I want to know how fast a micro SD card is? It is increasingly important to know the writing and reading speeds precise, especially the first value if you recur regularly to the camera and you like record video in 4K . For such resolution, it is necessary to have a micro SD with specific features, a minimum to guarantee correct operation. Something similar happens with the transfer of large files or a large volume of photos, for example. The faster the micro SD, the less time we have to wait for the task to finish.
How to measure the speed of a micro SD card
Having said that, how can we Check the speed of writing and reading a micro SD card Exactly? As in most of the occasions, Google Play has the answer and is given in the form of an application.
In our case, we propose the A1 SD Bench app , which will show us precisely the read and write speed of a micro SD card .
The interface is simple and is divided into three tabs. The most outstanding is the first in which appears a series of rows in which the different memories of the phone are shown. In our case, we list the micro SD memory, the internal memory of the smartphone and the RAM memory.
If we click on any of these icons, the app will start a test of several minutes to check the read and write speed of the selected memory. Once the test , the app clearly shows in its interface the speed in MB / s marked in green.
In this regard, it should be noted that the first value will indicate how fast the card is when copying files in it. As for the second value, it precisely allows us to check how effective and fast that card will be at the time of, for example, copying photos from the micro SD to the PC or even to the internal memory of the smartphone.
And do not forget that if you want to perform a speed test of your Internet connection, either by 4G or WiFi, you also have at your disposal the app of the Speed Test of the ADSLZone Group.
