The CompactFlash Type II (CF Type II) card is a variant of the CompactFlash memory format, distinguished by its thicker 5 mm design compared to the 3.3 mm Type I version. This larger form factor allowed it to support higher-capacity storage solutions, including microdrives and advanced flash modules. Widely used in professional digital cameras, camcorders, and industrial applications, CF Type II offered reliable performance, robust durability, and compatibility with Type I slots in many devices. It played a key role in early high-capacity portable storage.
