Memory cards are an essential part of our digital life day in day out, and also one of the best options to store all your data, pictures, music, e.t.c. Media cards have always been around for quite a bit of time. With the first one invented in 1994, the digital storage scene has since then evolved to give us what we have now. Memory cards, also known as flash cards, are electronic flash memory data storage devices used for storing digital information. They are commonly used in portable electronic devices such as digital cameras, mobile phones, tablets, portable media players, video game consoles, and personal computers.
Sizes on SD cards can be measured in megabytes (MB) and with sizes ranging from 10 megabytes to 512 gigabytes, the possibilities are endless. They come in different classes, brands, sizes and speed. The most commonly used type of media cards is the Secure Digital type (SD) and most mobile devices use the microSD cards. Classes are also divided into the Speed class and the Ultra-high Speed class, depending on what class is compatible with your device and the read and write speed you desire.
