Nikon, SanDisk and Sony propose larger, faster memory format

Professional photography and High Definition (HD) video applications require a new generation of memory cards capable of processing significantly larger files. To address the imaging industry’s future speed and capacity demands, SanDisk, Nikon and Sony proposed a new card specification whose performance and storage capabilities surpass those of existing memory cards. Once accepted, the new format will enable exciting new possibilities in the professional imaging and video markets.

The proposed specifications achieve data transfer rates of up to 500 megabytes per second (MB/sec)3 (theoretical maximum interface speed) using the highly versatile PCI Express4 interface. The increased speeds will enable imaging and video applications that could not be accomplished using the current CompactFlash specification’s Parallel ATA (PATA)5 interface. CF6.0, released in November 2010, offers maximum performance of up to 167MB/sec.

The new specifications’ faster speeds enable continuous burst shooting of massive RAW images. The enhanced performance also allows users to quickly transfer storage-intensive high-resolution photos and videos from the card to a computer. The specifications combine high-speed data transfer with low power consumption via a power scaling system to extend battery life.

In addition to industry-leading performance capabilities, the new memory card specifications also meet the future capacity and durability requirements of professional imaging applications. The proposed new format has the potential to extend theoretical maximum capacities beyond two terabytes (TB)6, making it especially useful for high resolution images and HD video applications. Similar in size to a CompactFlash card, the new format’s access control function and highly durable form factor produce a combination of physical ruggedness and reliability that is indispensable for professional usage models.
