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 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
