The increasing megapixel count of digital cameras can result in extremely large image files which lengthens the time required for the camera to capture the image and save it to the digital film card. SanDisk has designed its new SanDisk Ultra II SD cards so that large image files can be saved in less time and photographers can take additional pictures more quickly. The SanDisk Ultra II SD flash memory cards feature a minimum write speed of 9 megabytes per second (MB/sec) and a average read speed of 15MB/sec.
