What would you all suggest for a hard drive configuration when Windows 7 comes out? I'm planning on getting some kind of RAID 0 going for increased performance, but I also want some RAID 1 data protection... I have the space for a maximum of eight 3.5 inch hard drives at the moment.

My current setup:
1 x ST3500630AS 500GB 7200 RPM w/Windows Vista Ultimate 32-bit & Programs. (Direct MoBO connection)
1 x ST3500630AS 500GB 7200 RPM w/Windows 7 Ultimate 64-bit & Programs. (Direct MoBO connection)
2 x WD1001FALS 1TB 7200 RPM - RAID 1 mirroring, storing all my media, documents, web files, downloads, etc... (Connected to PCI RAID card)

I was thinking of adding two WD3000HLFS 300GB 10000 RPM's in RAID 0 to the mix when Windows 7 is officially released. One will be just for the Operating System, the other will serve for all my Program Files. I'll move the two ST3500630AS 500GB 7200 RPM's into a RAID 1 mirror and store all my files except video on them. The two WD1001FALS 1TB 7200 RPM's will remain in RAID 1 and store all my video media.

Does that sound like a decent plan to improve performance while maintaining and increasing storage space?
