I have set up my first RAID 0 with 2 320GB HDD after researching the internet. The problem (if it is) is that now it shows up as 1 HDD with only 320GB when I go into My Computer. I thought that it was supposed to show a total of 640GB. Is this how it is supposed to be? I used Intel Matrix Storage Manager that came with my computer to accomplish the RAID setup.
