A SanDisk SD card is a small memory card that can be used for extra storage in many portable media devices. It is quite common for digital cameras and video cameras to save their data to these cards. They can hold a lot of data, some up to 64 GB, and they’re easy to use. Reading these cards requires the use of an SD card reader. Most computers have one installed internally, but external readers are available for systems that do not. Writer Bio
