"BEST" is quite a subjective term. Even worse "BEST way for me", while relative, isn't much help either. Implied by its name, RAID sets up disks redudantly in attempt to either improve read/write performance, or to create data back-up, among other valuable features. If your ultimate goal is to create a second image of your build, then RAID 1 is what you're going to need, as it provides mirroring; whereas RAID 0 only increases space and speed.
In general, nothing has really changed in how to install software, so what you've read on 1-year-old hardware is still going to work for anything you procure in the future. Also, for what it's worth, setting up RAID with SSD+HDD is not a good idea, and here's a thread that more or less addresses the issue:http://www.tomshardware.com/forum/276907-32-raid-configuration
