SanDisk Ultra II card features a minimum write speed of 9 megabytes per second (MB/sec.) and a minimum read speed of 10MB/sec.* (Results based on testing with the popular HDBENCH benchmark software; actual results in digital cameras will vary by camera model.)
The Ultra II cards are primarily targeted at serious photographers with 4-megapixel or higher resolution digital cameras that require fast, high capacity digital film cards to quickly shoot many high resolution images.
