Elanzer:

Note: always measure read speed with this command:
* in left slot: '''dd if=/dev/mmcblk0 of=/dev/null bs=4MiB count=100'''
* in right slot: '''dd if=/dev/mmcblk1 of=/dev/null bs=4MiB count=100'''

If you can afford '''''destroying''''' all your data, you can test write speed. But be careful, you will need to create a new partition table, afterwards! You can use [http://www.gp32x.com/board/index.php?/topic/56915-gparted/ Gparted] to make new partition table.
* in left slot: # '''dd if=/dev/zero of=/dev/mmcblk0 bs=4MiB count=100'''
* in right slot: # '''dd if=/dev/zero of=/dev/mmcblk1 bs=4MiB count=100'''
