Yes, looks pretty good. For completeness, please also
- list size in KB (from /proc/partitions/ or fdisk -lu)
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.
root@host-3u9ak0vmgb:~ # fdisk -lu /dev/sda You must set cylinders. You can do this from the extra functions menu.
Disk /dev/sda: 0 MB, 0 bytes 128 heads, 32 sectors/track, 0 cylinders, total 0 sectors Units = sectors of 1 * 512 = 512 bytes Disk identifier: 0x00000000

This looks strange, it has not actually reported the size, just '0 sectors' above, and as you mentioned the last partition does not end at the end of the drive.
- 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 most cards it's the same number for linear and random, but for some cards, one of the two is larger. The FlashCardSurvey lists both numbers, so you can see the few exceptions.
