I have both a cheapie Kingston 1GB SD card and a 133x Kingston 1GB
card -- the 133x is very obviously faster by a really significant
amount in the DS2. Do you have a suggested method of comparison
that I can try out?
You can get a sense of relative speeds by setting the camera to
Manual exposure, choosing 1/1000 second or so, and timing several
runs from the start of a burst of five exposures to when the busy
light goes out. Without further instrumenting the camera, that's good
enough for me.
I did timings like that on the DS a long time ago now, with 32x, 45x,
60x and 80x cards. The improvement from 32x to 60x is appreciable,
from 60x to 80x virtually insignificant. I'd say from those tests
that a 66x card would likely be right about the limit for the DS.
Different brands and models of card will perform with some variations
as well. The Sandisk Ultra II generally compare well, but I haven't
tested them against the Kingston. I tested them against the ATP, PQI
and Transcend cards I have.
