I conducted an empirical test with my Digilux-2. I ascertained from Panasonic that its max write speed is 2.3mb/sec. A 1gb SD card will hold c.91 RAW exposures in the D-2. That's about 10.75mb per exposure. Doing the math, it should take the camera c.4.67secs. to write a RAW exposure to any card that has a write speed of 2.3mb/sec or greater. My actual results: 1) with a basic card it took about 11 secs for the camera to clear for the next exposure; 2) with a Sandisk Ultra II card it took 6.5secs. The Ultra II writes at 9mb/sec., per Sandisk's website. Obviously I'm missing some factors) here. What are they? And would one of the new-fangled 150x cards reduce the time further, in this context?
