Changing the subject again and not answering the questions. To most home users uptime isn't critical. I don't use RAID at home, my main system if I had a hard drive failure of my boot drive would be back up in about 20 minutes from an acronis image I keep updated on an external drive.
Uptime is important though to many businesses as the one I mentioned. An hour of downtime equaled thousands of dollars if not more of loss where I was working, and this wasn't a huge shop. I'm still looking forward to seeing benchmarks regarding single drives being able to keep up with hundreds of users accessing the same database compared to RAID.
