The Type II CompactFlash card is also known as MicroDrive, which will be discussed further down this storage media list. SanDisk describes their CF cards as "size of a matchbook and only weighs half an ounce". There is a controller card that allows for faster transfers. These cards are the most popular because of the decent price and the support throughout many digital cameras.
