i dd'd first 512bytes from my sd card in mmc reader where i have /var and swap of the running system to this test card which i tested with a usb-adapter, so i did not use the entire size, because the mmc card is only 4GB and test card 8GB. but i guess this makes no difference, since i only use the 3rd partition for tests.

- make sure that the cutoff number for --random is the same
you mean where the throughput starts to begin worse, that this is the same for linear and random?
- for cards that don't do --random (not this one), also check if there is a FAT optimization (--find-fat --erasesize=xxx)
ok.
