microSD for Extra Android Storage
A Tad Smaller
Hard to Believe
Adapters allow a microSD card to plug into a full-size SD slot. The half-gram microSD is 15 x 11 mm.

Remember floppies? It would take 21,000 floppy disks to hold as much data as this 32GB microSD card. See floppy disk.
Introduced in 2019, a 1TB microSD card (red arrow) is resting on a 17-pound hard drive from the 1990s. The tiny card holds 1,600 times more data. See hard disk.
