Memory card article Ap-Ju issue

[Mazawatea]

I read with interest the article on memory cards and worked my way through the ratings and relevant speeds, but when I checked my cards, they all have the letter C with a number2 or4 or 6. I cannot find any reference to this 'C' in your article. I believe this is a class reference and is an industry standard for write / read speed?
So how does a Sandisk ultra 11, labelled SDHC,15mb/s class 2 compare to a Kingston SDHC class 4 with no speed listed? (both 4 gb)?

Re: Memory card article Ap-Ju issue

Kingston use new speed "class" ratings known as Class 4, 6 & 10. These are the speeds in megabytes per second (MB/s):

Class 4: 4MB/sec minimum data transfer rate
Class 6: 6MB/sec minimum data transfer rate
Class 10: 10MB/sec minimum data transfer rate

So...if Kingston 'C4' SDHC card stands for 4mbs/s, then what does the 'C2' mean on the Sandisk ultra SDHC 15mb/s ?
pretty please.

Now I've got it..........the class number is the MINIMUM read-write speed for that card!!!!!!!!
