14 DAY TRIAL // Although CF (CompactFlash) memory cards seem to be loosing ground, compared to their Secure Digital (SD) counterparts, the truth of the matter is that there are still certain specific areas (such as that of high-end DSLR cameras), where this standard reigns supreme. For this reason, the fact that the CompactFlash Association (CFA) has just announced the new CF 6.0 specification comes as a very pleasant surprise, especially since it enables an enhanced level of performance and faster speeds. The new CF 6.0 specification includes a new Sanitize Command, Trim Usage Guidelines and an Operating Temperature Range function (enabling the use of CF cards at higher temperature ranges) along with adding Ultra DMA Mode 7 which supports 167 MB/second speed. Without a doubt, the most important enhancement brought about by this new specification is the Ultra DMA Mode 7, that provides an interface speed of 167MB/s, which, coupled with 48-bit addressing defined in the CF 5.0 specification enables the development of CompactFlash cards with up to 25% more throughput performance. The Sanitize Command provides an efficient NAND Block Erase of the entire user data area to return the CF card to “fresh” state before reuse or repurposing, while the Trim Usage Guidelines provide improved write performance consistency. Mr. Shigeto Kanda of Canon and the CFA chairman of the board said; “As the Chairman of the CompactFlash Association I am pleased to introduce CF 6.0 on CFA’s fifteenth anniversary continuing our tradition of performance leadership.” “The higher performance provided by Ultra DMA Mode 7 will further increase the capabilities and value of both camcorders and DSLR cameras.” “These backward compatible improvements of CF 6.0 are expected be a significant benefit within the professional imaging and video markets and will firmly establish CompactFlash cards as the highest performance professional card solution for the foreseeable future,” concluded Mr. Kanda.
