[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I just did an extremely unscientific test. I put a freshly formatted 16GB Sandisk Extreme 30MB/s SDHC I card in my M240 and turned it on and off several times. Then I did the same with a freshly formatted 16GB Sandisk Extreme 45MB/s SDHC I. Both cards are Class 10 (if I understand the lingo). The camera is ready to shoot with the 'slower' card in a little less than half the time as with the 'faster' card (unscientific, but probably pretty close). Why? Frank? Anyone? --Bob On Fri, Apr 10, 2015 at 5:58 PM, Frank Filippone <red735i at verizon.net> wrote: > First, the way the camera accesses the data and the card itself determines > the save ( or read) speed.
