I have an 80 GB running Windows and Apps, a 13 GB running my Page File and an 80 GB for storage. I also have a laptop with a 7,200 RPM 80 GB.
The best of all worlds would be one blazing fast drive like a 10,000 RPM Raptor for Windows and Apps and one 250-500GB drive for storage.
Or two small 7,200 RPM drives set up in a RAID 0 running Windows and Apps. and a giant 250-500GB drive for storage.
But I want one of these.

LOL, nothing like a 100 TB system when you have storage needs.
