CompactFlash is a type of memory card used to store data in various electronic devices, such as cameras and music players. It was first introduced in 1994 and quickly became popular due to its small size and large storage capacity. CompactFlash cards are known for their durability and speed, making them ideal for capturing high-quality images and videos. These cards come in different storage sizes, ranging from a few megabytes to several terabytes. CompactFlash cards use a specific type of connector, allowing them to fit securely into compatible devices. Although newer memory card formats like SD cards have gained popularity, CompactFlash remains a reliable choice for professional photographers and videographers.
