Speed does matter
I have other Sandisk CF cards that have a lower writing speed but as I progress is learning more about photography, the research indicate that faster writing speeds were better for shots that involved wildlife and nature. I purchased what I could afford at this time and was amazed at how much faster this Extreme III card was over my other cards. It worked perfectly and we took over 500 shots in RAW format during a trip to Chicago recently. Great product.

AWESOME FAST CARD!!
I have a Canon EOS 1D MARK II that will shoot 8.5 frames per second that i bought this card for. I do a lot of shooting at air shows, such as the U.S.A.F. THUNDERBIRDS, and the U.S. NAVY BLUE ANGELS. In the past I have used various cards including the Extreme II, and ALL of them failed me and were not able to keep up with me and the jets that i was photographing. Many times in the middle of a burst the camera would stop and I would have to wait several seconds for it to finish writing to the card.....which if you have ever shot an air show you know that even ONE second at an air show is an eternity to wait....by the time you blink it is too late you missed the shot!
This card kept up 99.9% of the time. There were only two times that it paused on me at a recent air show, and fortunately that was at the end of a burst. This card is blazing fast and I love it!!!
I am considering upgrading to the 1D Mark III...if I do then I will invest in the Exteme IV, but for not the Extreme III is one AWESOME card. I have two now, and will probably buy another when they come down in price.
If you are considering this card....then BUY IT! You won't be disappointed!!!

Works great!!!
I bought this specifically for my Canon dSLR and it works great. No problems at all and I used about 4GB, so far on RAW pictures plus JPEGs. I highly recommend it.

great
what an invention!!! I put this in my Canon Rebel XT (8 megapixle) and the lcd showed that I had 999 pictures left on the SanDisk.. that's the highest number my canon will dislplay. haha. I took 1341 pictures at once with this and it wasn't even half way full. and that is using my full resolution at 8 megapixels... which came out to be 3-4 megabites per picture

Does the job
Like most other cards, this one does the job. I can count on the fact that this is a quality card with a lifetime guarantee. It writes and downloads fast.
