SanDisk and Sony have 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 with the ExpressCard industry standard.
SxS memory cards will target workflow improvements for professional camcorders and non-linear video editing systems.
The 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.
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.
PCI Express has a maximum data transfer speed of 2.
5 gigabits per second, twice as fast as PC Card-based storage media. The target transfer speed of SxS memory cards is 800 megabits per second.
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.
