CFkártyák

CFkártyák, also known as CompactFlash cards, are a type of legacy flash memory storage device. Introduced in 1994 by SanDisk, they were one of the earliest widely adopted solid-state storage formats. CFkártyák use a parallel interface and are physically larger than many more modern memory card types, such as SD cards. They were popular for use in digital cameras, camcorders, and other portable electronic devices due to their durability and relatively large storage capacities for their time.

The physical connector of a CFkártyák consists of 50 pins. Two main types exist: Type I and Type II. Type I cards are thinner, measuring 3.3 mm in thickness, while Type II cards are thicker at 5 mm and could accommodate additional components like miniature hard drives, though this use case became less common with the rise of flash memory. CFkártyák support various flash memory standards, including FAT16 and FAT32 file systems.

Despite being largely superseded by SD cards and other newer technologies in consumer electronics, CFkártyák remain in use in some professional photography and videography equipment, industrial applications, and older devices. Their rugged construction and robust interface contributed to their longevity in certain demanding environments. The development of CFast and CFexpress card formats, which utilize faster serial interfaces like SATA and NVMe respectively, represent the evolutionary successors to the original CompactFlash standard, offering significantly higher performance.
