The internal storage of mobile phones has increased dramatically in a matter of a few years. I remember the first Android phone I had, an HTC Desire that appeared in our lives back in 2010 and that housed only 512 MB of capacity inside. Today, if our economy allows it, we can acquire terminals that reach up to 1TB of storage. An evolution so gigantic that, paradoxically, it has not prevented even the same phones from allowing the possibility of inserting a microSD card to increase the storage size.
The world of microSD cards can be a bit vast and complicated for those who are not very into this type of accessories. Specifically, in this article we are going to explain what a Class 10 microSD card consists of. We have chosen this type of card because it is the one that you must purchase for your mobile phone and it guarantees the minimum quality standards in terms of writing speed and storage management.
What is a microSD card?
A microSD card is a small accessory, in the form of a small plastic rectangle, in which we can store files of different kinds. So that we understand each other, it is like a hard disk raised to the minimum power. It belongs to the SD standard made up of various types of cards according to their physical size. We focus on microSDs which are the smallest. MicroSD cards can be divided by the amount of storage they hold.
How to choose a good microSD card
According to its size, they are divided into SD, SDHC and SDXC cards, thus remaining as follows:
- MicroSD cards: up to 2GB
- MicroSDHC cards up to 32GB
- MicroSDXC cards up to 2 TB
It is logical that, in case you want to buy a card for your mobile, from now on you look at the microSDXC model although do not worry: if you look for a card larger than 32 GB in a store, it will automatically be the SDXC model. The next thing you have to look at, and this is very important because the speed and efficiency of the card will depend on it, is the class to which it belongs. The class of a microSD card refers to its reading and writing speed. The higher the class of a microSD, the faster it will record and read the content you send it. What happens if you put a microSD of, for example, Class 2 in a high-end mobile, as internal storage? Well, the mobile will go much slower, because you have assigned your phone a reading and writing level that is too low.
In your expert we recommend that you buy a Class 10 microSD card whose read and write speed is 10 MB per second. Currently, it is the fastest reading speed that exists and the price of them is not as exorbitant as it might seem. For example, in online stores like Amazon we can buy a microSDXC card for a price lower than 20 euros and from a well-known brand like Sandisk. We have even found a Class 10 microSDXC card of no less than 256 GB for the price of 22 euros and with good opinions although keep in mind that the brand is not so well known.
