microSD Cards are the most compact and dense data storage format you can buy. Latest microSD Cards can store 2TB in a volume smaller than a penny! A shoebox full of them could hold every movie and TV show on your favorite streaming platform, with room to spare, and a room of microSD Cards can store the entirety of the internet. In this video, we open one up and journey down to the nanoscopic scale to see how 16 dies, each as thin as a strand of hair, filled with over 200 layers of NAND flash cells, store all your photos and files.
