@ 2010/11/30The CompactFlash card is a common storage medium in imaging devices today from D-SLR cameras to high-end HD video cameras. The current CF specification is based on the old PATA interface, which is much slower than more modern interfaces on the market.
Three industry heavy weights have come together to propose a new standard for a next generation storage medium to the CompactFlash Association. The new specification is being proposed by Sony, SanDisk, and Nikon. The idea the three firms are offering for ratification as a standard uses the much faster PCI Express interface.
The PCIe based specification would have a maximum theoretical bandwidth of 500MB/s whereas the existing PATA interface tops out at a much slower 167MB/s. The faster speed would allow photographers to shoot large resolution RAW images in bursts without having shot limits and lag that are currently common with bursts of high-resolution images with the existing storage medium.
