SD cards, How They Work and How to Use Them

Secure Digital cards (SD cards) are used to store data on most digital devices. Most modern cameras and electronics use SD cards to store information and data. The first secure digital SD card was developed by SDA (SD Card Association) and starting from August 1999, Panasonic, Toshiba, and SanDisk joined efforts to improve the standards of SD cards. 
In order to use SD cards your device must be compatible and capable to read information from the card. New modern electronics such as smartphones, digital cameras and laptops comes with an SD card slot that support reading and writing of these cards.

How data is stored in an SD card

Modern SD cards stores data in form of electronic components called NAND chips. The chips have no moving parts and allow data to be written and stored on the cards. Because of the smart technology of the chips, data can be quickly transferred to the cards in speeds that exceeds CD and hard drive medias. Unlike other media storage devices, SD cards don’t wear out easily and data can be written thousands of times. This amazing feature makes SD cards as one of the most suitable and resilient media for long lasting use.Modern SD cards stores data in form of electronic components called NAND chips
