Confused about RAID volumes

[dextor]

Drives in questions are 2x 1TB WD Caviar Blacks.
Motherboard: Gigabyte P55A-UD3

I'm a little confused on creating raid volumes, I want to make a RAID 0 array:

1. Should I create 2 raid volumes, first volume say ~200GB for OS + game/app files (to short stroke), second volume for storage (1800GB)?

2. OR should I create one RAID0 volume of all the 2 TB, and when installing Win7 just create 2 partitions, same sized as above?

3. What if I just create a RAID0 volume of 200GB only? Will the remainder 1800GB not get recognized by Win7? If it does get recognized, how will it show up? As two drives?

4. Can a RAID0 volume of 200GB AND a RAID1 volume of 900GB (1800GB/2 since mirrored) be created? If yes does that negate any beneficial effects of short stroking the RAID0?


Thanks in advance.
