For the record, I have a 6 year old machine running Windows 7 with a RAID-0 setup (asus p5k-e motherboard, WD 250gb drives), and it has never had an issue. It it typically on 24/7, but it has gone through many power outages where the UPS ran out of battery and it hard-reset.
I do, of course, keep all data on a separate regular drive, along with an external back-up of that. So if the RAID-0 did die, it wouldn't be a big deal (and I could finally move to SSD!).
Anyways, the point I am trying to make is that RAID-0 is not as "crazy unreliable" as some people would have you believe.
