Yikes. I only googled and saw that there were a bunch of decisions to be
made.

May I presume to ask if "any" RAID method is useful in the home
environment, where all you really care about is safety of your data?

In my case, I don't even need one Terabyte disk, but now I have two.

My other option is to make one disk a Linux disk and the other a Windows
disk, where I can skip the whole GRUB mess since the HP Pavilion will boot
off of any disk you tell it to at startup.
