Thanks for the thorough evaluation and thoughtful advice! Much
appreciated.  I agree it makes a lot more sense and I will follow your
suggested procedure (when I get to purchase the extra drive ;-) )

PS, a related question: some measurements posted on the web suggest that
RAID10 in f2 mode is far superior to n2 (the default?) when it comes to
reading performance, and only mildly inferior when writing.  I tend to
go with f2, unless someone tells me it's a bad idea.

Thanks again for everyone's input.
