In today’s article we will talk about How to choose the best MicroSD card? looking at the types that are specifying their speed and capacity.
First of all, we must know what is an SD Card? An SD card is a card of a reduced size, which has the function of storing information in portable electronic equipment . We can differentiate them by their size, capacity and class.
Today we will talk about their types, seeing which are the fastest and with the largest storage capacity. Next, we will mention and explain each of these types of SD Cards.
SD card types
As we mentioned earlier in this article, there are a variety of types of SD cards, which are differentiated by different factors that we will mention below.
What types of SD card are there according to their size?
The first differentiation that we can observe is the size of the SD cards , deriving from there names that distinguish them from each other due to this characteristic, such as: SD card that has a size of 32 millimeters high x 24 millimeters wide x 21 millimeters wide. thickness. The size that follows is 21.5 millimeters high x 20 millimeters wide x 14 millimeters thick, receiving the name of mini SD card.
Finally, we have the micro SD cards, which are 15 millimeters high x 11 millimeters wide x 10 millimeters thick. The latter is commonly used for devices such as cell phones .
What type of SD cards are there according to their capacity?
Another way in which the types of SD cards can be classified is by their capacity , which can be seen marked with the letters SC, HC and XC. Each of these letter codes refer to the storage capacity of the cards. Next, we will see what each of these letter codes means.
- The first of all is the SD card with the acronym SC which stands for Standard Capacity. These cards can hold 2 GB, being one of the ones with the least storage capacity .
- The one that follows the SDSC cards, are the SD HC cards, which mean High Capacity, having the possibility of storing up to 32 GB.
- Finally, we have the SD XC cards, which stands for Extended Capacity. This type of SD card has a large storage capacity , having the possibility of storing 2,000 GB.
What type of SD cards are there according to their speed?
The last classification that we will see with respect to SD cards is that of speed. Of all the ones we have seen, this is the most extensive, differentiating itself into six types, of which we will explain more in depth.
- The first of all is Class 2, which has a writing speed of at least 2MB per second. Its use is limited to taking low resolution photos and videos .
-
- Class 4 is the name of SD cards that have a minimum of 4MB per second in writing, giving us the ability to record in 720p.
- Another of the types that we have are the so-called Class 6 counting in writing with a minimum of 6MB per second. Like Class 4 they record in 720p
- Those of class 10, have a writing speed of 10MB per second at least, having the video capacity in 1080p.
- Coming to the end, we have the UHS Speed Class 1, with which its minimum writing has been 10MB per second, offering 1080p of video.
- Finally, we have the UHS Speed Class 3 , which offers us a minimum of 30MB per second writing, allowing us to record videos in 4k resolution .
What are the SD cards with the highest speed and capacity?
Having seen the different types of SD cards, the question often arises, which are the fastest and with the highest capacity? When choosing a graphics card. Since when choosing it we have to do it thinking about our needs , choosing what we are going to use it for.
After all, we can conclude that if we want a higher speed SD card we should opt for the UHS Speed Class 3 , but if we want higher capacity our SD cards are the XC ones. We could opt for the Ultra High Speed microSD card designed by Samsung.
