It's a little hard to believe that, not too long ago, even the biggest and priciest memory cards had a storage capacity of just a few gigabytes. These days, you can fit an entire terabyte of storage into a chip that's smaller than the tip of your finger, and smaller capacity cards are available for a dime a dozen.

As the name suggests, microSD cards are a more compact version of standard SD cards commonly used in digital cameras. MicroSDs are used to bump up the storage capacity on devices where size is a major factor, such as handheld game consoles, action or security cameras, cellphones and tablets.
