To purchase a microSD card, a number of factors should be considered. Do not forget that there are different types of micro SD cards, each with specific characteristics.

For this reason, in this section, we face the most frequently asked questions from users so as not to make you make mistakes during the purchase.

What Is a Micro Sd Card Exactly?

The microSD format corresponds to the smallest flash memory size currently available. Its dimensions are 15 x 11 x 10 mm. It was developed by SanDisk and subsequently adopted by the SD Card Association. Right from the start, it had a large following thanks to the advantages offered by its small size.

What Are the Main Uses of Micro Sd Memories?

Currently, their main use is for smartphones. They can be used to save files, to create backup copies, and even as an extension of the phone’s internal memory. They are also used very often in digital cameras.

Likewise, they are also used in drone cameras. Another increasingly popular application is as a memory for the video game console. For example, they are used a lot in Nintendo’s latest console, the Nintendo Switch. Of course, with the increasing increase in their storage capacity, their uses are always growing.

What Are the Advantages and Disadvantages of Micro Sd Cards?

One of the main advantages of micro SD cards is that they allow you to store a large amount of information in a very small space. In this way, documents and files can be easily transferred. Furthermore, their price is not only not very high but is constantly decreasing.

On the contrary, a disadvantage of micro SD cards is that they do not have the same capacity as other memories. However, in recent years this difference has been significantly reduced. Furthermore, given their small size, they can be easily lost. That’s why, if you’re a little distracted, you’d better be careful.

How Many Types of Micro Sd Cards Are There?

First of all, there are the original microSD cards, with a maximum memory of 2 GB. However, nowadays, they can be considered obsolete. The next-generation cards are micro SDHC, with a maximum capacity of 32 GB. And finally, there are microSDXC cards that can store up to 2 TB.

  1. MicroSD (maximum 2GB)
  2. MicroSDHC (32GB maximum)
  3. MicroSDXC (maximum 2TB)

The microSDXC is classified by classes. Each class indicates the writing speed of the card. Those of class 2, have a speed of 2 MB / s, those of class 4, 4 MB / s, and so on. Then, there is the UHS (Ultra High Speed) class, which has its own classification. Within this class, we have the subclasses UHS-I, UHS-II, and UHS-III.

What Do the Micro Sd Card Logos Mean?

The logos of the microSD cards offer information on their characteristics. You can take a look at the product to get an idea. Thanks to the logos you will be able to know which devices they work with, what their speed class is, and which interface they are compatible with. And of course their ability.

How Do You Use a Micro Sd Card?

Their use is quite simple. Just insert the card into the appropriate slot, on a phone or other device. Next, you have to wait a few seconds until it is recognized. It is recommended to insert it with the appliance turned off. Also, remember that you must never force them to enter.

However, there are adapters for using Micro SD cards as if they were of normal size. There are also USB adapters that allow you to read them on computers that don’t have a card reader.

What Are the New Video and Application Specifications?

Recently, the SD Card Association added two new variables to the SD card specifications. It is the Video Speed ​​Class and the Application Performance Class. The first represents how appropriate a card is for recording videos.  The second, however, indicate how appropriate it is for applications.

The symbols used for the Video Speed ​​Class range from V6 to V90. The speeds, in these cases, range from 6 MB / s of the V6 to 90 MB / s of the V90, with which it is possible to record videos at 8K.

The Application Performance Class presents classes A1 and A2, which indicate how appropriate it is to register applications or their data.

Who Is Recommended to Buy a Micro Sd Memory?

They are recommended for those who need to expand the memory of their mobile phone or camera, or even for those who want to have a light storage unit that takes up little space. And, in general, for all those who want to enjoy all the advantages they offer.

  • Small and light
  • Practical and versatile
  • Moderate price
  • Functional
  • They are easily lost
  • Limited capacity

What Attention Does a Micro Sd Card Require?

Like any electronic product, microSD cards require a lot of attention. Fortunately, these are very durable devices and can even withstand a washing cycle in the washing machine. However, it is better not to challenge fate and avoid contact with water.

They must be stored in rooms with low humidity. It is best to remove them while the computer, mobile phone, or camera is turned off to avoid losing data. Otherwise, use the safe removal function. Also, when not in use, it is desirable to store them in their cases so that they do not bend or break.

Purchase Criteria

Below, we analyze a number of important factors to consider before purchasing a microSD card. In this way, you will be more satisfied after the purchase. We don’t want you to regret your purchase after a couple of months.

  • Uses
  • Memory capacity
  • Speed ​​of writing and reading
  • File format
  • Resistance
  • Brand


You may need a microSD card for a cellphone, tablet, eReader, camera, computer, or video game console. Many are looking for a micro SD for GoPro or the like. Or even to move information between different devices. Whatever your intended use, it will clearly determine the card you will need.

In general, to take photographs, any type of card is fine. If you need to record high-quality videos, you should choose a card that allows you to. The same goes if you want to install mobile applications. For HD video you need to have a class 4 card or higher and record in Ultra U3 or higher.

Memory Capacity

The memory of a card is typically measured in gigabytes (GB). As you can imagine, not all micro SD cards have the same storage capacity. The higher this is, the more information can be saved. Of course, you must also take into account the maximum capacity supported by the device in which it will be used.

Speed ​​of Writing and Reading

The Speed ​​Class of a card is what will indicate its minimum write speed. This speed is measured in MB / s. However, with the advent of the SDHC and SDXC models, the SD Association created the new UHS Speed ​​Class.

For smartphones, this is a key factor in enjoying a good experience. Nowadays, it is advisable to opt at least for a class 10 card. For recording videos, you need to use the upper classes such as the V60. With it, you can record videos in 4K and 8K format.

File Format

The format or file system is how a storage unit organizes the content or information stored. For this reason, in order to use any type of storage drive, it must be formatted. There are several types of formats, some of the most common are FAT32, NTFS, and ExFAT.

It is important not to overlook this factor when buying a micro SD card. Unfortunately, not all devices or equipment accept the same types of formats. For example, new SDXC cards can only work with the exFAT format, compatible only with Windows XP SP2.


This is not a secondary problem. The resistance of a microSD card is a very important aspect to consider. There is nothing more frustrating than losing information stored on a storage device. And even more so, if it’s very important information and you don’t have a corresponding backup copy.

The best brands offer very resistant microSD cards. They are made to withstand shocks, the effects of magnetic forces, and X-rays. Some can even withstand long periods of immersion in water without suffering damage. The truth is, accidents do happen, so prevention is better than cure.
