 SanDisk and Sony SxS memory card specification : SanDisk Corporation and Sony Corporation announced that the two companies have agreed to a Memorandum of Understanding (MOU) with the intention of developing the SxS (S-by-S) memory card specification, with high-speed transfer technology compliant to the ExpressCard industry standard. SxS memory cards will leverage the technology strength of SanDisk and Sony corporation, who have a long and successful history of co-developing and promoting flash memory products. With this high-performance and high-reliability memory card, both companies are targeting workflow improvements for camcorders and non-linear video editing systems.

 SxS memory card specification
The SanDisk and Sony SxS memory card specification uses flash memory and complies with the ExpressCard industry standard, and the card connects directly to computer systems through the high-speed PCI-Express bus. ExpressCard has been rapidly adopted by PC manufacturers to replace the legacy PC Card form factor, giving the SxS memory cards broad support in post-production hardware. Sony will adopt this high-speed SxS memory card specification in its “XDCAM EX” series professional camcorders. SxS memory cards from SanDisk and Sony are expected to be available later in 2007.
SxS memory card - Specifications
• High-speed data transfer of large video files. SxS memory cards are the first native PCI Express solid-state storage media. PCI Express has a maximum data transfer speed of 2.5 gigabits per second, twice as fast as PC Card-based storage media. In addition, SanDisk and Sony have optimized the technology protocol for controlling communication between hardware and SxS memory cards to enable high-speed transfer of large files, such as high-definition video, to PCs for non-linear video-editing. The transfer speed of SxS memory cards is 800 megabits
• Compact Size. The SxS memory card specification uses ExpressCard/34 modules (width: 34mm, height: 5mm, length: 75mm), half the size of PC Cards. This enables the design of professional camcorders that are smaller and lighter, while still offering high storage capacities.

Significant milestones have been the Memory Stick PRO format in 2003, the Memory Stick Micro in 2005 and Memory Stick PRO-HG in 2006. I am delighted by today’s joint announcement of this new technology, which expands our collaboration to a new area, the professional video market, offering great benefits to users in this field. With the introduction of this SxS memory card, we will seek to expand its use throughout professional video applications to enable highly efficient workflow systems.”
