SxSTM memory cards will leverage the technology strength of SanDisk and Sony, 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 professional camcorders and non-linear video editing systems.

The SxSTM memory card specification uses flash memory and complies with the ExpressCardTM industry standard, and the card connects directly to computer systems through the high-speed PCI-ExpressTM bus. ExpressCardTM has been rapidly adopted by PC manufacturers to replace the legacy PC CardTM form factor, giving the SxSTM memory cards broad support in post-production hardware.
Sony will adopt this high-speed SxSTM memory card specification in its "XDCAM EXTM" series professional camcorders. SxSTM memory cards from SanDisk and Sony are expected to be available later in 2007.
