RAID 5 might be a contributing factor in performance issues. However, the politics behind RAID 5 is such that most believers simply cover their ears when someone suggests to reconsider and look at alternatives such as RAID 1+0.

IF your organization has an open mind, consider reading about the reasons why RAID 5 is not optimum - look at the "Why should I not use RAID 5" article (and others) at http://www.baarf.com
