When you buy a new micro SD card. The word “SDHC” is marked below the English letter of “micro”. This is the abbreviation of “High Capacity SD Memory Card”.

1. The highest Class level is not the best, and the speed matches the mobile phone is  the best.

The higher Class level is faster than low class level transmission speed. This statement is correct, but this is not mean that memory cards with high Class level can be used arbitrarily in the mobile phone.

Because higher level of memory cards such as Class 10 can be used in less products and mostly used in professional SLR equipment, they are not suitable for mobile phones. Even if you run on a mobile phone, its transmission speed does not have any obvious advantages.

Just choose the corresponding level according to your own choice, otherwise it will be a waste of money.

2.The memory card capacity should be moderate, the larger capacity of mobile SD card the more resources will be occupied.

The 256G large-capacity memory card can indeed allow you to store more data, but if you don’t have much storage, there is no need to buy a large-capacity memory card. Why to say that?

Because the card capacity not only affects the reading speed, but also drags down the mobile phone processor and accelerates the battery power consumption, which are invisible losses.

Although a large-capacity memory card allows you to obtain a large space capacity, if you don’t use much space, you can only waste the reading and writing functions of the phone again and again.

3. Focus on the brand, not just the price

Just look at the price to choose a TF card. This is a very big misunderstanding. It can be seen from a casual search that the price of TF card is actually quite different, especially for high-capacity TF cards. Some friends buy cheaper one to save money. As a result, broke after a short period of time, resulting in heavy losses of the saved data. And choose big brands such as Kingston, Sandisk or eFOX to provide life-long warranty service, product quality is excellent, data is more secure.
