Hello again and thanks for the kind words.
command only over-writes the format configuration data and the clean all
command over-writes every sector on the SSD / HDD with zeroes, if you want to wipe secure erase
the SSD you would want to use the clean all
I would suggest that you not do too many 'clean all' as it will shorten the overall life-span of the SSD but a few will be alright.
If you are referring to doing the align
command to the SSD have a look at Step Two #4
of this tutorial. SSD / HDD : Optimize for Windows Reinstallation
