Which memory card to choose for a smartphone or tablet?
Built -in memory in a smartphone and, especially, a tablet, is never enough. Modern flagship models of mobile gadgets already have “on board” enough to have enough to take themselves for a while. After that, the files in the device can be updated.

And what to do to owners of budget devices, which the developers have not equipped with a large amount of internal memory? Correctly, expand it due to the SD card. In this article we will tell you how to choose it correctly for your device.
In order to choose the SD card, you need to understand the characteristics of such memory cards. Let's dwell on them in more detail.
Form factor
Various gadgets support different types of maps. Most often, modern devices are supported by format maps: SD, Minisd And Microsd. Before choosing a card, determine the one that can be inserted physically into your device.
Volume
Of course, the larger the card, the better. But, this is a superficial judgment. Firstly, your gadget may physically not support large volumes. And, secondly, there are other characteristics, in addition to the volume that is worth paying attention to.
Manufacturers offer SD cards that are marked SD 1.0, SD 1.1, SDHC, SDXC. Be sure to choose this marking when choosing. SDHC (Secure Digital High Capacy) cards allows you to store up to 32 gigabytes, while SDXC (Secure Digital Extended Capacy) can work with 64 gigabytes and above.
But, the biggest problem is that not all gadget manufacturers can support the SDXC brand cards. Therefore, before buying such a SD card, you need to find out if you allow you to use such a card.
Class
But this characteristic is very important. The card class means the speed of processing (reading and recording) data. In modern gadgets, you can use a map of one of five classes:
- Class 2 - speed 2 Mb/s, multiplier 13x
- Class 4 - 4 Mb/s, 26x
- Class 6 - 6 MB/s, 40x
- Class 10 - 10 MB/s, 66x
- Class 16 - 16 MB/s, 106x
Important: a multiplier is written next to the data processing speed. Some manufacturers mark the cards not by class, but by the multiplier.
Many consumers pay attention to the volume, and not to the class of maps-memory. And choose a carrier from the ratio volume/price. But, this approach is fundamentally not true. For modern smartphones, you need to choose cards with a high class. Many manufacturers of mobile devices even began to indicate in the instructions for their gadgets the required class of a map-memory class.
- The above list shows the minimum data speed corresponding to its class. On Class 2 cards, you can record information at a speed of at least 2 MB/s, and Class 16 is a large or equal to 16 Mb/s
- If you use a map-memory only as a place of storage of information, then the class is not important for it. But, if the card is used to record or play streaming videos, then the higher the class, the better is better. Moreover, for shooting on your smartphone video in HD format It is necessary to use cards with a class not lower than the “sixth”. A FullHD not lower than the "tenth"
- As for cards of the 16th grade, they, due to their price and specifics, are used only by professionals
- There is a separate class of card memory, which is marked UHS (Ultra High Speed). Maps of this class maintain 104 MB/s processing speed. But they can only be used in devices that support UHS technology
How to choose a memory card for your smartphone or tablet?
- Now we know the differences between memory cards and their characteristics. What else needs to be known when choosing a carrier for smartphones? Of course this is a supported volume. This has already been said above
- In addition, when choosing a map-memory, take into account the power of the gadget battery. Even if your smartphone or tablet can support large volumes, its battery will say to you. Energy consumption when using large volumes increases significantly
- You also need to take into account the "name" of the manufacturer. Cards Sandisk, Toshiba or Kingston They deserve confidence, and when using cards of a little -known Chinese company there may be trouble. This is especially important to consider if you are going to store important information on such a card
