The SanDisk 600x is a Compact Flash card, not SDHC. Class 10 listing alone is not really useful for our purpose. Class 10 only means minimum sustained rate of 10 MB/second. Some cards such as the SanDisks also rate maximum sustained speed, which in their class 4 is 15MB/s and their class 10 it's 30MB/s. I have seen that rating to be more reliable than minimum rating.
Thanks for the article. I didn't pay attention to the Compact Flash since there wasn't a photo and it was mixed among the SD cards, I missed that. But, some people use the Nano Flash recorder on top of their cameras, so it might be useful to them.
It is recommended a minimum of class 6 SD cards, so having a minimum does give a starting point. I'm currently using class 6, as that was the fastest available at the time I made the purchase. Like always, something faster and cheaper is always on the horizon.
