This review just shows what every indepth analysis of RAID has shown, it has very little benefit for increasing performance and in many cases it can actually lower performance.
If you are in a single user enviroment and you want to decrease load times and boot times going RAID is not the way to do it. Using one extremely fast drive is the best way not RAID.
Go to www.storagereview.com and look at the leader board. Buy one of the fast drives. The only reason to buy raid is to say "I have raid" and to feel good about your scores in synthetic benchmarks.
