re: write speed DVD MPEG2 video runs at 8 to 10 Mbits/sec (1.2Mbytes/sec) Mpeg4/DivX Video is ok with about 1 Mbps (0.15 Mbytes/sec) Almost every card writes with speeds in excess of those (and reads faster) So compressed (Mpeg 2 or 4) digital video is not an issue. Many transitional Digital Camera/camcorder use Mjpeg (Motion Jpeg, every frame is separately compressed) or other low compression algorithms. In that case a fast card may be required. A good Digital camera that can shoot bursts of several Mpixels shots may require a fast card. So far the bottleneck is processing power to do realtime compression of video streams Companies that have a (slightly) better write speed or another technical difference push it via marketing in order to convince customers that they need it.
