None. I ran "cmp /dev/sda /dev/sdb" after mirroring the disk.

On weaker CPUs like Atom (ARM?) this can be an issue, I guess?

More details: top reported 99% CPU usage of the cmp process.
iostat reported about 88 MB/s throughput, when simple reading would
give 130 MB/s.

I'll try the 64 bit version to see if it behaves differently.
