Most of the time the difference between a 40x card and higher is going to be nothing. The transfer of the files to your computer will be slightly longer. In the camera however, how often do you fill up your buffer? That's going half answer the question for you. If your buffer is always full maybe you could benifit from a faster card, if not, why spend more?

I don't know about most cameras, but the 300D is slow, the 350/20D faster (40x or a bit under 6Mb /sec).
Faster memory costs more and can't hurt anything but your wallet, and MIGHT DL faster froma card reader to the computer.
I have the dumb, slow cards for my Rebel, as faster cards give me no benefit. I plan to get a 1Bg Ultra (40x or 5.6mb/sec write speed) so that when i upgrade to a 30D or what have you I am ready, but then i'll probably need an Extreme card (80x). Or SD maybe...

| Thanks guys. I am chosing between a sandisk ultr II (60x) and a Sandisk Extreme III (133x). Guess I'll just go for the slower one and save a bit. |

Maybe you can save little bit more by going for the Kingston Elite Pro Series (blue label, not the orenage one). They're 60x too, even if kingston doesn't state it that way. I'm using one 1G on my 350D and runs ok and fast.
Look at computer parts retailers instead photo retailers, their margins are lower. |

does this also change the speed at which the card is erased? When I use one of my older cards and hit erase instead of format it takes FOREVER! I prefer format because of this and I'm sure it is better than just erasing but am not sure if either has a better advantage. Format goes in seconds. I have noticed my cards also take forever when downloading to my kanguru portable hard x-drive...wonder if this would help there too.

That's one way of looking at the question of card speed. I used the Rob Galbraith database to find the fastest card for my camera and spent the extra money. I figure I will likely take the card with me when I upgrade to another camera. And my next camera will probably be able to take advantage of cards even faster than what I bought. And if you shoot continuous bursts, as in sports/action type shooting, you never know when that last little bit of extra performance may get you THE SHOT.

I have a Lexar pro 1GB 80x and a Kingston Pro 1024MB (40x I think). The write speed is not suppose to be different between the two b/c the DR's buffer speed is really slow but Lexar is consistently a bit faster by about 1 sec after a 4 shot burst. Can't explain why.
Let me ask you a question, do you shoot so many frames that you are always waiting for the buffer to clear? If so get the fastest possible. If not and you take one shot at a time then you can probably go with a 40x card and be fine. Also a faster card can download from your camera/card reader to your computer faster as well.
I think if write speed is very important to you, then I'd probably get atleast 80x, if not 40x and up.

I have two of these and I have yet to have them not keep up with the camera.
