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 DESTROY your data, you can test write speed with this:
in left slot (be careful!):
- dd if=/dev/zero of=/dev/mmcblk0 bs=4MiB count=100
