Believe me mate, I wish things were simple when it comes to storage and backup as well, but it's one of the most complicated things I have ever had to deal with, be it for myself or others. I've built several high capacity backup systems for businesses over the past year or so and it's not getting any easier to decide upon what to use. When it comes to my own system, it's going to have to be perfect and impressive (because I'm like that...) and obviously that makes it even harder :/ Haven't looked at the link you posted yet, but I would imagine that 120MB/Sec would be very hard for an onboard RAID controller to sustain when the computer is performing other operations. It also may not handle large data volumes very well, I've had experience with that in the past. Looks good on paper but then you go to back up a 5-600GB partition and it grinds to a halt.
