Compact FlashCompactFlash cards are designed with Flash memory, are PCMCIA-ATA functional. They are non-volatile and solid state, thus more durable than disk drives, and consume around 5% of the power required by small disk drives. They operate at 3.3V & 5V power levels, and can be swapped from system to system. CF supports capacities from 8MB to 3GB. CF cards are able to cope with extremely rapid changes in temperature. Industrial versions of CF cards can operate at a range of -45C to +85C.
Used most often in palm devices (which won't take larger form-factor cards), digital cameras, and a wide variety of other uses, including desktop machines.
Comes in several different varieties:
CF I (3.3mm thick)
CF II (5mm thick)
The CF version 2.0 specification supports 16MB/sec data-transfer at capacities up to 137GB.
