Hi all Wouldn't RAID 1+5 be better with the operating system and programs on the RAID 1 parttiton and the cache on the RAID 5. This is common with Exchange because of Transaction Log based design of it? I also believe this to be Microsoft recommendation for genericWindows 2000? Please feel to correct me if I am msitaken. Bye for now.

I have read in Tom's book that it is better to use RAID 5 Volumes, this because the access to the cache drive is faster, because it doesn't have to write in two drives the same information. Recently I have noted a slower access to Internet in my clients, although I have incremented the percentage of RAM used for cache. Do you think that I will get a better performance if I reinstall the hole server, this time in a RAID 5 volume? or is there another way to solve this without reinstalling the hole system? Thanks.
