CF storage cards are based on the Parallel ATA interface (PATA). These products are used in Professional Imaging, both for still and video recording markets. These products are preferred by professionals for both their performance and their handling characteristics.
CF storage cards are also used widely in the industrial and communications market, due to their robustness and handling quality.
The high level performance capabilities of CF storage cards continues to improve with each version. To get the most out of your CF card purchase, match or exceed the host (camera) capability with the CF storage card version. For camera use, both the write speed in camera and the read speed for later image processing should be considered.
