On a new computer I am planning on building this summer I was thinking of raid 0 for the OS W7. Is this wise or not? The main thing about this is that I am not going SSD as they are way too expensive at this point. I want to do it with WD Caviar black but the smallest is 500GB. So that would give me 1TB o space. How would you partition this setup. I will have other hdd that I will use for video, pictures and music. Video I have will use almost a TB alone as much is Avi format from capture. It will keep getting bigger over time. Anyway back on to my question. Can I do a raid 0 on a 140GB partition for the OS. I know 140GB sounds big but Vista and 7 just keep adding things in and it takes up space a if you got it use it. Anyone care to iterate.
