When looking at SD or SDHC cards they talk about class? What are the classes and what do they mean? - sdhc to sd howto
I have a new Canon Rebel EOS 450D camera SXI. I am looking for the biggest and fastest memory card I can get money. And in the online search, I found lots of information, but nothing to compare. The difference between SD and SDHC? Is it only with high capacity? I use the camera? How do I know which card is faster? Is there a difference in quality, too?

SDHC is an extension of the standard SD. You can use both types of cards in his rebellion, but more than 4 GB and is compatible with SDHC-compatible. Houses which are only in SD, you can not use SDHC.
The classes give the writing on a newly formatted card. Class 2 is 2 MB / s, Class 4 of 4 Mb / s, and, as expected, the level 6 6 Mb / s.

Classes define the minimum * speed of the card. For a photo and video, class 6 is the fastest class.

Class 2: Minimum transfer rate of 2 Mbit / sec
Class 4: minimum sustained transfer speed of 4 MB / sec
Class 6: minimum sustained transfer speed of 6 MB / sec
However, cards can move faster than the maximum rate *, and yes, there is a difference in the quality of the card, usually on the very rapid transfer and internal components.
I just do it for you: The better and faster your cards in camera at this time SanDisk Extreme III SDHC cards, which can transfer 30 MB / s are. You will see that the speed of an external card reader connected to the computer in the chamberSpeed is slower, because the buffer of the camera itself, not because of the card. Extreme III SDHC 4 GB can be found, 8 GB and 16 GB in size.
There is also a discount on SanDisk cards now so that it is a good time to buy. Try http://www.buydig.com example.
= SD Card 2 GB or less
SDHC Card = greater than 2 GB.
Yes, the device may SDHC cards.
