Yup, I know.

Perhaps it's the brand, my friend. That could be one other factor that we forgot to look at among other factors already mentioned.

Class 6 cards are hard to find from where I live so I have fewer choices than others here. That's why I mentioned that as long as it reports to be genuine and hence doesn't make me feel that I wasted money, I'm all good. Thanks for your showing your concern, by the way.

I may try the dd; never said I wouldn't...I just need some time to read how to do it correctly. But I know that I will just get tired knowing that different benchmarking programs will give different results anyway...so only one thing that will give me peace of mind that is consistent will be the question as to whether my card gives me the "promised" 6MB/s or not. If another benchmarking program reports a faster speed for my card, it's a bonus and a plus. If not, I at least expect it to report that my card is a genuine Class 6.
