How do microSD cards work?
Data Storage Data in an SD card is stored on a series of electronic components called NAND chips. These chips allow data to be written and stored on the SD card. As the chips have no moving parts, data can be transferred from the cards quickly, far exceeding the speeds available to CD or hard-drive media.
