could u tell me,what does writing speed mean on memory cards,will a higher speed make any difference 2 picture or video quality,does the class 2,6,etc just mean that it will b faster 2 download from card 2 computer-i will b getting a casio h10 4 christmas,and would like 2 know what card would b best.thank u
In answer to your question, the speed of the card will not have any impact on the quality of a still image, but may have impact on the quality of a movie if the card cannot record the data at the rate the camera can deliver it. If the card is the bottleneck, then this will cause the number of still image frames per second to be reduced. For movies, if the speed is too slow to capture the video, then you risk drop-outs when the camera cannot write to the card at the rate the movie data is generated.
The following link to the SD card site shows the speed, so a speed class of 4 should be OK for HD video. http://www.sdcard.org/developers/tech/speed_class/
Did you get any response from your question (or any other discussons you have had)?
I have the same question. I have a 2G SD card (not SDHC). Testing the card for read/write speed, it will write at 3.9 MByte /sec, making it approximately equivalent to a class 4 card (by my understanding). This "should" be OK for the EX-H5 in theory. I want to know if this is sufficient, or if has anyone had experience of this limiting the camera's 'continuous shoot' capability or video quality.
