The PC in my sig currently has an Intel 975x chipset, meaning I have have (and use) the ICH7R southbridge for RAID. Currently, I have two 160GB HD's in RAID 1. So far, they're about half full and performance is pretty good. However, having the ICH7R for RAID also means I can try Intel's Matrix RAID. For example, I can have half of each drive be RAID 0 and half be RAID 1, thus giving me 240GB of space. Is it worth it for me to do this Matrix RAID setup? I'd like to get as much performance, space, and security as I can out of this current setup, however mutually exclusive those three concepts might be. But if there are problems with the Matrix RAID technology, or I may not see much of a performance benefit from the RAID 0 part, then I don't want to do it. With all that in mind, I'm basically laying out my options and asking you which one I should do: 1. Keep the RAID 1. 2. Go Matrix RAID, 1/2 and 1/2. 3. Go JBOD. P.S. If I decide to go JBOD from RAID 1, I won't have to do any reinstalling of Windows, right? One disk would boot up and I'd just wipe the other one, correct?
