I should have 2 Hitachi Deskstar T7K250 160GB SATA2 next week for my first raid setup. I'm running a DFI NF4 Ultra D, but I have no experience with raid. I've read some stickys but I'm still unsure about a couple things. With raid 0 will I get 320gb of space or would I be limited to 160gb? And when putting these drives in raid 0 would I set them both to master, or how does that work?
