Quick question about RAID

[Descent]

So I recently found another Hard drive by the same manufacturer, same size (250gb) and very similar model.
My Current HDD:
Western Digital WD2500JS-00MHB0
The one I found:
Western Digital WD2500JD-22HBB0

So I'm wondering if I can put these 2 into RAID 0. Or would it be JBOD?
Also I presume I need to format both and set it up as RAID in the BIOS, not sure how to get to the RAID menu though (Abit QuadGT IX38). Any help is greatly appreciated! Thanks

Thanks a lot!
So I will lose my data stored on it? Not a problem if so, going to install Windows 7 anyway.
