Win7 software Raid

So as long you have mirror or backup of OS volume..you should be safe?

**TECHNICALLY** you are correct - you *CAN* make it work.

But to be honest, any data that is worth putting on a mirrored RAID array means that it is data that is worth keeping. Requiring one extra step / requirement to restore a failed system means that you introduce one extra point of failure, and one extra source of risk.

I would highly recommend that you go with hardware-based RAID, like your motherboard's onboard RAID controller, or an external USB/eSATA disk enclosure that supports RAID. That way, it is irrelevant if your OS disk dies, if your registry is corrupted, if you have a power surge that fries your motherboard, etc.

With hardware-based RAID, you can always take out a hard drive in the RAID array and mount it on ANY Windows or Linux system to access your data. Again, if your data is valuable enough to put on a mirrored RAID array, then it is valuable enough to invest just a little bit more time/energy/money to eliminate the potential risks that you get with software RAID.
