CompactFlash - True IDE interface|
Mr. Shigeto Kanda of Canon and the CFA chairman of the board said, "The development under way for the CompactFlash 133MB/sec True IDE and PCMCIA ATA interfaces means that the CompactFlash interface will not restrict the sustained data transfer rate of CompactFlash cards in the near future. Having the fastest interface data rate of any flash cards is a significant step for CompactFlash. Data write performance of digital SLR cameras as well as other high performance cameras will not be limited by the flash card interface."
CompactFlash rate - Ultra DMA
DMA interface mode is also included and reduces the processor power required to manage the CompactFlash data transfers. Ultra DMA 33 and UltraDMA66 interface modes increased the CompactFlash maximum interface data transfer rate to 66MB/sec in 2005. Ultra DMA 100 and Ultra DMA 133 will increase the maximum interface data rate to 133MB/sec in 2006. Both of these DMA interface modes are well defined and tested by their usage on IDE hard disk drives.
CompactFlash flash card - Storage capacity
The end-user cost of CompactFlash cards has decreased from over $5.00/MB ten years ago to four cents/MB today. The maximum available capacity of CompactFlash cards has increase from 2MB ten years ago to 8GB today. The currently available capacities up to 8GB provide the best storage solution for the new multi-mega-pixel DSLR cameras, Pocket PCs and other devices. Faster PCMCIA ATA Memory and I/O modes will also be added in 2006 to provide a maximum PCMCIA ATA interface transfer rate of 133MB/sec.
CF Specification Revision - CompactFlash solution
In addition to CompactFlash data storage cards, there are CF+ cards that provide I/O capability. VGA, Ethernet, modem, serial, parallel, digital phone, GSM, Bluetooth, Ethernet wireless, wand & laser barcode scanners, finger print scanners, TV and GPS CF+ cards are all available and widely used in the CF+ slots in today's Pocket PCs. They are also used in notebook PCs. The CF Specification Revision 3.0 is available to download free from the CFA web site at http://www.compactflash.org.
About CompactFlash Accociation
The CompactFlash Association is a non-profit, mutual-benefit corporation that promotes adoption of CompactFlash as a worldwide, ultra-small, removable storage and I/O standard for capturing and transporting digital data, audio and images and performing I/O functionality such as modems, Ethernet, serial, BlueTooth wireless, laser scanning, etc. The CFA, which makes the CompactFlash and CF(logo) trademarks and CF & CompactFlash Technical Specification available royalty-free to member companies, is headquartered in Palo Alto, CA.
