I have not looked at the web site, but if it is helpful, by all means take advantage of it. If it contradicts something I said in class, please let me know so I can let you know if it or I was wrong. Yale Patt I'd like to recommend this site to the class. On every page there is a description of the RAID levels and advantages/disadvantages along with applications. I think the class might like it. http://www.acnc.com/04_01_00.html There are other sites with more or less information but this site offers some clear illustrations and examples of applications. Thank you <>
