Hi, I'm thinking of putting my OS in a special disk, but I wonder. What would be faster for gaming, a single raptor has overall a faster response time but less bandwidth then 2 7.2k drives. Also what about cache? I think 2x 16mb cache would be faster then 2x 8mb?. I've read some reviews but I still can't decide. Any opinions? Is the performance so minimal, that I'd better buy a single 320gb seagate barracuda 10 drive? I don't care about noise btw.
