Not at all, and since I am here in this forum as much to learn as to help, probably more to learn...I did some research and I did discover, as you said there is some potential for increased read speeds because of the dual data locations, however; I don't suspect that Windows 7 software raid solution would support that, but I just can't say with any degree of certainty. There actually doesn't seem to be a whole lot of broad support for this even in some of the more sophisticated hardware solutions. I did spend some time on the WD Community forums and between those posts and some referenced Knowledgebase links, it seems that it may not be a good idea to use anything that is not WD Enterprise Class in a raid environment (probably more importantly a Windows dynamic disk, software raid environment). Seems to have something to do with no longer being able to use the WD-TLER utility with these drives to speed up the process by which the internal drive diagnostics handle errors and it's generally reported that because of that the raid system (software or hardware) may often drop the drive from the array. There are also a lot of customer reviews on Newegg, from customers who purchased these drives specifically for what you had in mind and they're reporting problems with their raid configurations. Seems to be a very well regarded drive across the board for single drive environments, Tom's Hardware only report the Hitachi Disk Star as a possible rival, some noise issues seem to be a consistent report. However, since you said that performance is not really your number one concern. And data protection, is, as it should be I would simply refer back to my original suggestion, image your drive and or backup your data, no raid configuration will beat it for ultimate data protection. Also, and I know you probably know this already but it's never a good idea to mirror a drive that contains your operating system, so disk imageing is really a very good solution and the built in backup in windows 7 seems to do a very good job of this.
