Thanks for that, very interesting.

I just conducted a similar test (no, I don't have a movie to watch :)

K10D, RAW (DNG) Test, SanDisk Extreme III 2GB SD card:

a.. 75 RAW exposures, 1.25 exp per sec or 0.8 secs per exp average.
a.. finish write :: ~9 seconds

I'm not sure if this card is actually this much faster, or if I did 
something wrong... its a fairly simple test though.  Looking at the 
timestamps, the files are from 11:36:30 through 11:37:36, which would be 
about right (I notice the K10D EXIF timestamp is when the file is written, 
not when the shot is taken)

Anyway, assuming this is correct... considering this is basically a 133x 
card (20mb/sec), it perhaps illustrates the differences between read/write 
speed.  Cards are often quoted in read speeds, or some combination of 
read/write, wehen determining the 150x.  SanDisk do specify 20mb/sec read 
_and_ write for the extreme III.

In any case, either of these results are impressive, being somewhere from 
13MB/sec to 18MB/sec or something.  If anyone has looked at Rob Galibraith's 
SD speed tests on cameras 
(http://www.robgalbraith.com/bins/multi_page.asp?cid=6007), this blows away 
anything else out there.

The D80, say, only manages RAW writing at 8.34MB/secd on the SanDisk Extreme 
III, and thats its fastest result. Looking down the list you'll see various 
150x cards that are substantially slower... say the 'Transcend 150X 4GB', 
only does 5.56mb/sec, again shows the 150x isn't everything.

I'd recommend the Extreme III's to anyone getting a K10D, I'm pretty damn 
happy with them.
