The advantage of doing RAID

I am astounded by the amazing performance I am getting with 3 7200 RPM HDD's configured as RAID0. It is quite amazing the speed even though the HDD's are not "super fast" by today's stds.

I got a 160gb hdd from frys for $50 making this a value proposition. It also helped that nvidia hardware RAID was embedded in my motherboard and windows natively supports it.

I have to now seriously consider this for future desktops (with backup though).
