Okay, I don't know much about RAID but since I have 2x500GB drives in this, I want to try it. This is what I want: Drive 1 - 500GB - P1 (500GB) Drive 2 - 500GB - P2 (250GB) - P3 (250GB) Drive 1 has 1 partition, 500GB in size. Drive 2 has 2 partitions, 250GB per in size. I want to set up a RAID 0, software based, between Drive 1 w/ P1 and Drive 2 but with only P2 not including P3. Would this work or is the RAID set up exclusive to the drive itself and I cannot partition stuff? I want to set up 500+250 GB for OSX and the rest for Boot Camp.
