The difference between CF and SD card

   The early application of CF cards was mainly in PDAs and digital cameras in the early days, and later gradually expanded to MP3 players, GPS devices, and laptop, because they are compatible with a variety of operating systems and hardware platforms, such as: DOS, Windows, OS/2, MAC and UNIX. The CF standard has become a standard interface under the promotion of CFA. On this interface, different manufacturers can develop different products to connect to it, which makes the equipment supporting the CF standard also have a strong ability to expand and upgrade. We used to apply MP3 players, but now with the increasingly functions of mobile phones, Mp3 are replaced by phones.

   The SD card is small and widely used in digital cameras. It is a brand-new memory card production. The SD card is consistent with the MultiMedia Card in appearance, and is compatible with the MMC card interface specification. However, that in some products such as mobile phones, SD cards and MMS cards are not compatible. SD cards are more expensive than MultiMedia Cards of the same capacity.

   CF card is the first memory card introduced, and it is also the most popular memory card. There are many reasons for the popularity of CF cards, the most important of which is the high quality and low price. Compared with other digital memory cards, the storage cost per unit capacity of CF cards is almost the lowest, and the speed is relatively fast, and large-capacity CF cards are easier to buy.

   The CF cards that we can contact are divided into two types: CF Type I/CF Type II. Since the CF memory card slot is backward compatible, the Type II slot can use both CF Type II cards and CF Type I cards; while the Type I slot can only use CF Type I cards, but not CF Type II cards. Cards, So we have to pay attention when we purchasing and using.
