Industrial Grade CompactFlash (CF) Card

The Industrial Grade CompactFlash (CF) Card is a highly ruggedized, reliable, and durable memory storage device based on the Parallel ATA (PATA) interface. It is specifically engineered to meet the stringent demands of industrial and embedded computing environments, unlike consumer-grade cards.
