Hi,

I'm running my Windows 7 installation and all of my apps from an SSD for performance reasons. Since SSD's can instantly die at any moment, I'm looking for some kind of data backup strategy. Right Now I regularly backing up the drive image on a hard disk, but that only happens once per day, which is not enough for my taste.

So I got an idea: What if I created a software raid 1 of the SSD and partition on my Hard disk?

All data would be mirrored on both drives, making this a lot safer. But what about performance? Will Windows 7 detect that the SSD is faster than the hard drive and always read from the SSD? Or will it randomly read from both, thus reducing read performance?

Thanks,

Adrian

Edit: I just found this article which basically answers my question. Feel free to close this post.
