Thanks for the share. Hm, well in my opinion this is the simplest I found. I'm sure someone will be able to make something better, or perhaps someone may come up with a GUI for the F3 program to make it "point-and-click" friendly.

Or, if you have a Microsoft-based OS you can try the other program I attached; I find it simple for those who are not used to the command line since it has a GUI ("point-and-click" with the mouse).

As far as difference, yeah I found differences too as mentioned in Post #1 (which, based in my own tests, seem to differ based on OS used, benchmarking program used, manner on which the storage device is plugged).

I did read in one of the threads here though, that there are benchmarking tests that do a "sequential" write and there are others that do a "random" write. I'm no programmer and no techie guy, so the way I understand it, the speed being reported differs depending on how the test runs (e.g. sequential or random)? Maybe the community can help me understand.

Anyway it won't matter much to me quite honestly, since there is always this variance in reported speeds, what I just took into consideration is whether my MicroSD card is what it is; in other words as long as it is reporting the speed that it should at least report (assuming that the benchmarking program is "legit"), then I would be comfortable knowing that I didn't purchase a fake card. Whether it reports a higher benchmarking speed than the "promised" speed is just a bonus or a plus, but not really a requirement for me.
