I am shooting RAW+JPG and have Extreme III 20mb/sec.

I am trying to see would I get any benefit in speed by going to 30mb/sec edition or would I lose any speed by going to Ultra II 15mb/sec.

Therefore I am wondering did anyone have a chance to compare speed of G10's writing between these?

Thank you in advance!

Based on my G9 i can say that even the "slowest" of the 3 types is fast enough for the camera.
You'll gain the speed benefit only if you copy your pictures via a card reader.

My friend went from an Ultra II on an SD1000 (7MP) to an Extreme III 20mb/sec on the G10 (15MP) and he says it is noticeably faster transferring with a reader, and that's just a 5mb/sec difference. Nothing scientific though.

Are you talking about write speed from the g9 to the card, or card to your computer?

I don't think we can make that assumption based on G9. Manufacturer can change the pipeline between models. Otherwise all cameras would be writing with same speed and timing would depend solely on megapixels and card's write speed, which is not the case.

I am talking about speed camera is writing to card. In other words how many say continous RAW+JPG shots I can make in a minute.

I am talking about write speed from my _G10_ to the card.

Does anyone know how fast the G10 is capable of writing to the card in the first place? Seems like I read somewhere that the G9 camera can’t write to the extreme II cards as fast as the cards could be written to. In other words the camera was the slow part of that equation. But can the G10 with it’s new and improved processor write to the card faster? I went to the Canon website but couldn’t find the spec for writing speed. If we could get this number it would answer your question. I’d really like to know as well.

As the G10 with it's slightly more megapixels (and even with the faster DIGI 4) is slightly slower in continous shooting, i can't see more output of data on the internal bus directed to the memory card.
But this is just an assumption... ;)

I just switched to the G10 from the G9 and the write speed is defintively slower with the G10 - seems no matter what card I am using.

As it seems that there is no definitive answer I will be getting two 4GB cards in speeds I don't have and test myself.
