I guess that would mean that scattering unused space on an SSD between the partions, means the controller probably sees it as being used. I left chunks allocated at the ends of the drives as recommended. I was just wondering if my stripes would increase that wear level capability, as well as providing for emergency recovery space(s).

I'll check this out for sure. Thanks again.
