Compact Flash

Compact Flash card is a very small removable mass storage device that relies on flash memory technology. The CompactFlash card is about the size of a matchbook and only weighs half an ounce. There are two types of CompactFlash cards to accommodate different capacities: Type I cards are 3.3mm thick while Type II cards are 5.5mm thick. The card was designed based on the PCMCIA PC Card standard and can fit into a PCMCIA slot with an adapter. CompactFlash technology has resulted in the introduction of a new class of advanced, small, lightweight, low-power mobile products. These products include digital cameras, digital music players, desktop computers, handheld PCs (HPCs), personal communicators, Palm PCs, Auto PCs, digital voice recorders and photo printers.
