Is there any homebrew app for DS flashcards that will test the speed of the SD card? The card readers in the PC's here won't go any faster than 5megs per second and the little USB readers I have only do 4megs per second, so HDtach is kinda useless here and I'd like to do some speed testing. I'd like to see how my Transcend 2gig microSD compares to the Kingston 2gig microSD. I know the Kingston is faster (PoR didn't crash on me), but I'd like to see how much faster. Is there such a thing? It technically could be possible right? If no such app exists, someone should make one. It would be dead useful. Is there somewhere that lists accurate speeds of those 2 cards? Link?
