Thanks again for sharing, and for the information about "dd". That will help us get an idea on how different benchmarking tools run tests (i.e. sequential, random, etc.). In my observation, the different benchmarking tools give different results, so it will already be tiring (for me at least) to continue, so I just focused on whether my card is being benchmarked/reported as offering the speed that it advertised. Some benchmarking tests seem to give high speed results, some give low so. That's also the reason why I already marked the thread as solved. But it will be nice if more members would also check so that they can share their experiences.

At least now we know that "dd" does sequential (which most likely will really give high benchmarking results, if I understand it correctly).
