Very interesting that the I/O wait time is not reflected in iowait in the CPU stats.
One would think the CPU would be busy somewhere.
root@mobian:~# dd if=/dev/mmcblk2 of=/dev/null bs=8M count=100
100+0 records in
100+0 records out
838860800 bytes (839 MB, 800 MiB) copied, 16.0952 s, 52.1 MB/s
52 MB/s seems pretty fast. (though it is sequential and not random)
