Whenever a new phone is released that has a microSD slot, every buyer wants to expand their phone’s internal storage space, but is not sure on what microSD card to buy. The performance of a microSD card depends on what specifications your Android phone has, so you have to keep that in mind first.
Check if your smartphone has a microSD slot
Not all Android devices have microSD slots, even big flagship phones like the Samsung Galaxy S6. To find out if your smartphone supports microSD cards you need to open your phone and check, or read the smartphone’s manual. If your smarthphone does not have a microSD card slot, and you are interesting in buying one that supports microSD cards, you can get the new Samsung Galaxy S7 or the Huawei P9.
MicroSD Card Classes
The classes that microSD cards come in are: Class 2, 4, 6 and 10. The class number reflects at what speed rate the card will write and read. For example the Class 2 one will read and write at 2MB/S, and so on. So checking the class of a microSD card is important.
UHS MicroSD Card
UHS helps the MicroSD card to transfer data at high speeds of 312MB/s. MicroSD cards became UHS-1 and UHS-3 compatible, but to be realistic, UHS will not make any difference to your transfer data speed, and this only because at the moment there are no smartphones that support UHS.
SDHC and Micro SDXC
These are two different microSD formats, and it reflects the amount of data the microSD card can store. The SDHC can store 32GB of data, while on the other hand the SDXC supports 64GB and more.
Good MicroSD card will speed up the smartphone
Smartphone speed performance will increase using a good microSD card. When you store apps or photos on your microSD card, they will be saved at a faster rate, when you transfer files to another device they will be sent at a higher speed. Also, opening apps installed on your microSD card can have a bit of delay, because the command has to go through your phone and then to your microSD card.
When choosing a microSD card, there are many factors to take in consideration. Another guide line when buying one, is to buy from a respectable brand such as SanDisk, Samsung or Kingston. You can use the price of the microSD cards to get an idea of the quality of the card.
