CompactFlash (CF) is a mass storage device format used in portable electronic devices. The format was first specified and produced by SanDisk in 1994. It is now used for a variety of devices; most contain flash memory but some, such as theMicrodrive, contain a hard disk.
CompactFlash became the most successful of the early memory card formats, surpassing Miniature Card, SmartMedia, and PC Card Type I in popularity. Subsequent formats, such as MMC/SD, various Memory Stick formats, and xD-Picture Card offered stiff competition. Most of these cards are smaller than CompactFlash while offering comparable capacity and speed. Proprietary memory card formats for use in professional audio and video, such as P2 and SxS, are physically larger, faster, and costlier.
CompactFlash remains popular and is even supported in some new devices. For example, in 2008, Sony chose CompactFlash as the recording medium for the HVR-MRC1K tapeless video recorder over smaller MemoryStick cards or expensive SxS cards. In 2010, Canon chose CompactFlash as the recording medium for its new professional high-definition video cameras, and Ikegami devices record digital video onto CompactFlash cards through an adaptor.
In November 2010, Sandisk, Sony and Nikon proposed a next generation card format to the CompactFlash Association which would come in a similar form factor as CF/CFast but be based on PCI Express instead of Parallel ATA or SATA. The new format is targeted at high-definition camcorders and high-resolution digital photo cameras, would offer a target read and write speeds of 1 Gbit/s (125 Mbyte/s) and storage capabilities beyond 2 TiB, and is not backward compatible with either CompactFlash or CFast. TheXQD card format has been announced by the CompactFlash Association in December 2011.
