If it boots reliably from sdc1, as it does now, why would I want to do
that?

I may not have been clear as to my purpose. The OS on sda1 is *identical*
to the one on the SSD, sdc1. I hope to take advantage of the improved
speed of the SSD, but I do not utterly trust SSDs (nor hard drives, but I
come closer to trusting those). By having both, should the SSD fail I can
simply boot an identical system by making that choice in the GRUB menu. So
in this case it really is a feature, not a bug.
