SD Cards

SD cards, short for secure digital cards, are compact memory cards commonly used for storage in portable devices.


What does an SD card do?


Like most portable devices, a memory card allows you to carry your files and media with you. They are removable cards which store data from a device such as a digital camera or smartphone. Some PCs and laptops come with an SD card slot too, or you can purchase a card adapter separately. The compact nature of the card makes it easy to integrate into portable devices.


What size are SD cards?


SD cards come in three different physical sizes, standard, mini and micro. The size you choose depends on which device you plan to use and what card it can be used with.


Each SD memory card will have a capacity size too, given in GB or MB. This refers to the amount of data that can be stored on the card. Larger capacities will be more expensive so it is best to choose an SD memory card that meets your storage needs.


Why would you need an SD card?


Most devices today come with built-in memory storage to a certain capacity. However, it is very easy to use their internal memory up, and that is where SD cards are useful. They add-on to your personal device that can greatly boost the amount of media you can store at one time. You will not have to worry about having to delete important photos from your camera, or music from your smartphone. You can keep adding more to your library.
