SD Speeds on K100D

I just did some speed testing of SD on my K100D. Please feel free to share your results.

The testing method goes as follows:

- turn off AF
- turn off SR
- Select 'M' for manual
- 1/500 shutter speed
- continuous shooting from the function menu
- find a reasonably complicated scene to shoot so the files don't compress too well
- press and hold the shutter release until the rapid fire shooting.
- when the rapid fire shooting has to wait for a write to SD operation between frames, time the interval with a stop watch.

I was shooting a small contrived scene of items on my desk (a bunch of Canon lenses, actually). Unfortunately, JPEG will compress better the less complex a scene is so the test is not objective without also posting file sizes.
