I have just bought a new Canon camera with a card but wanted a spare SDHC card. With a plethora of makes, versions and speeds out there your article proved very useful for me buying spare cards. The article explains simply and clearly, even to me as a lay person, card speeds and which would be appropriate for my camera.

Thanks Andy

I don't understand any of this, I hate the big cards(600 photos), When I want to load the last few (say 6) I've just taken, it takes ages to go through them all and how do I avoid the ones I don't want?

Just bought a Canon G9 & your article was a great guide to the SD world.

Thanks for the helpful article. For P. Dean; the DPReview.com site posts camera performance with storage cards with each review they do, usually under that camera's review link for Performance or Timings and Sizes. They will tell you which card they used, and then the performance while using that card for various file sizes.

I appreciate the article and its logical explanation of info. I have looked on the DPReview.com site, but can not locate where they test cameras with different speed cards. I am interested in the Canon Xti and also the Panasonic tz3 as I am purchasing the newer versions of these as they become available. THe tz5 takes HD video, so I’d like more card speed info… THanks! pdean11@hotmail.com

The brand "Kingston" was not mentioned. I have always been very happy with this brand for both flash-cards and laptop memory. One company mentioned in the authors list offers a free computer scanner (to assess how much memory ones computer can accept). The misinformation produced by that scanner has made me "go off" the brand. Ripping ones laptop apart looking for the mythical second slot is a great waste of time.

Thanks for the information, very useful indeed. I wanted to comment on you suggestion to possibly buy a faster card that only a future camera might make able to take advantage of. With prices falling like big rocks, it doesn't make sense to invest in more capacity / speed than you need currently.

What causes SD cards to fail (magnets and crushing damage aside)?
