Some cameras and phones need specific types of memory cards for instance some will need stand-size SD cards and the other might need microSD cards.


People can note that all the device comes with internal storage, but still, they support memory cards, so it’s necessary for one to check the storage capacity of the memory card. Large storage capacity is better for those who want to store photos and with high megapixel of their cameras. There are some memory cards with specific features, they show the amount of space for photos, music or documents, so people should check if there is enough storage based on what they want to store.

Speed class is also a vital factor that should be known by people, although they are very few people who have the idea that memory cards come with speed class. Speed class is an indication of the minimum serial data speed, so memory cards have four different speed classes which are 2,4,6,10.
