Alright I have never even attempted to look up RAID or know anything about it so I am trying to expand my knowledge. What is the advantages of RAID. I currently have 2 500GB HDD's. 1 is my C: drive and 1 is my D: drive. If i were to put them in a RAID, what advantages would I see? How does it affect reformatting as well? Can you RAID these 2 drives when they are currently in use, or only when they are empty? I am actually running out of space on both these drives and am looking for another 1 TB drive either to replace 1 of the 500GB HDD's or to just add to both them. Would I be able to put that one in RAID? Well I better stop asking so many questions or they won't all get answered lol. Thanks for any help you have on the subject.
