The SanDisk ExpressCard product was designed for professional videographers who use the new generation of professional camcorders that record on ExpressCards instead of magnetic tapes, hard drives, or optical disks. With the SanDisk ExpressCard, professional videographers have access to a high-speed, solid-state digital recording solution for the first time. The SanDisk ExpressCard was developed for ultra-fast downloads of large video files and is ideal for on-site editing. Video can be quickly transferred to a notebook without additional cables or readers, allowing the card to be reinserted into the video camera as soon as possible. SanDisk and Sony jointly developed the SxS specification, which is optimized for Sony's professional video cameras, ensuring that ExpressCard memory cards support the high-speed performance required for professional video. The SanDisk ExpressCard carries the SxS logo and is fully compatible with Sony's XDCAM EX, which features two ExpressCard slots. ExpressCard is a standard developed by the Personal Computer Memory Card International Association (PCMCIA) as the successor to the PC Card standard. By connecting directly to your computer's PCI Express slot, ExpressCards can read and write data at least 2.5 times faster than PC cards. Unlike competitors, video recording professionals have access to the fastest digital solid-state recording solution with the SanDisk ExpressCard.
