There are some good points there about WHERE to use RAID.
Serving web pages from RAID, unless you're a huge hosting
enterprise, seems a little excessive.


Our use of RAID is more a requirement of storage size.
(ie: terrabytes of server data and growing)
The redundancy is a nice feature but I'm not sold on the
idea that it's any more reliable than getting rid of drives
half way through the rated lifespan.
