SAN JOSE, Calif. - SanDisk Corp., Nikon Corp. and Sony Corp. have announced the joint development of a set of specifications that addresses the future requirements of professional photography and video markets.
The proposed and new card format technology provides a roadmap beyond CompactFlash. The proposed specifications achieve data transfer rates of up to 500 megabytes per second (MB/sec), using the PCI Express interface. The increased speeds will enable imaging and video applications that could not be accomplished using the current CompactFlash specification’s Parallel ATA (PATA) interface. CF6.0, released in November of 2010, offers maximum performance of up to 167MB/sec.
The proposed new format has the potential to extend theoretical maximum capacities beyond two terabytes (TB).
The three companies proposed the specifications to the CompactFlash Association (CFA), the international standards organization, with the intent to standardize the format.
How do we get the physical card interface formats under control? My printer already has 4 card slot sockets in the front. Every time we buy a new camera, the memory card format is incompatible with the existing ones used by other family members. The proliferation of formats is getting out of hand.
This is good change suggested by introducing a new card format, but USB interface itself is capable of supporting the required data rate, that will also enable a great interoperability between the device and computer.
Introducing a new standard will create the compatibility issues, but it is good for earning revenues.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
