Alright, I'm sure this has been asked before but I was going through my equipment today looking to unload a few items I no longer need. I came across two unused SanDisk Extreme III memory cards. Both are 4gb SDHC cards and both are marked as offering 30mb/sec 200x read and write speeds. The difference? One is labelled as Class 10 and the other as Class 6. More specifically, the class 10 card simply reads 30 mb/s and the class 6 card reads "30mb/s Edition."
I am aware of the SDHC performance classes and what they mean. But, in the particular case of these two SanDisk cards - both advertising 30mb/sec 200x read and write speeds - is there any functional difference assuming they are put into service in the same device? Or could these simply be two otherwise identical cards, just labelled differently because they were manufactured at different points in the evolution of standards?
Any SanDisk users out there who can speak from experience?
