A photo opportunity lasts only an instant. If your digital camera is busy processing the last one, you're sure to miss the next one. That's where we come in. Our high-speed digital film helps your camera capture images faster, so you spend more time taking pictures and less time waiting on your camera. Lexar Media CompactFlash cards are individually speed rated so you know the minimum capability of the card. We use the same rating system used by the CD-ROM industry, where data transfer rate of 1X equals 150 kilobytes (KB) per second. The higher the speed rating, the faster your camera will be able to write images to the memory card.
