SD Memory Cards Writing Class i.e. Class 6 or Class 10 ?

[asnow]

I have a Canon Xsi (EOS 450) and I have a three 4GB SDHC cards (one class 4, one class 6, and one class 10). I've seen no difference in filling the buffer (in burst mode) between these cards. Therefore it appears to me that unless your camera can handle the higher transfer speeds there is no reason to go with a class 10.

Exactly right

Awesome. I shoot with the same camera so that's good to know. Now, do they transfer to the computer faster?

Transfer to the computer.... I would have thought it would be faster, however it doesn't seem to be noticeably much different. I was expecting that with the class 10 I would be seeing WOW that is much faster. That not way it appeared to me. Mind you I haven't timed it to have a definitive answer. Next time I fill the various cards I will time it and post my results.

In principle they should download to the computer much faster but this depends on the transfer method, how fast you card reader is etc ! but I find the faster the card with a good reader such a a Lexar you will get quicker download speeds.
