okay heres my problem, I have been running 2 hard drives striped (raid 0) both are western digital raptors. I just bought another hard drive for more space... basically a storage drive so i can keep just the OS on the striped HDD. The new hard drive is a WD caviar 7200 HDD. My question is what should i run without losing performance would i run a raid 0 + 1? Any help is greatly appreciated.
