I was doing a little work on one of my computers here at the house tonight. I tried to explain to someone what the different RAID levels are and wasn't doing a very good job of it. That is when I remembered this site has a very good explaination of several different types of RAID. Well I hope this explains this RAID thing to some of you and acts as a good information point for the rest of you.
