There are servers that are specifically designed for database servers.
They have battery backup write-caching disk controllers.

It all depends on what you're going to do with the database.  Is it
write-intensive?  RAID 1 is good for redundancy, and has mediocre
read/write performance.  RAID 5 will give you good read performance but
weak write performance.  Of course, RAID 0 is good if you want to
participate in the DBA's X-Games.  If at all possible, go with RAID 10.
Then you get good read and write, and redundancy.  Of course, it'll cost
a little more.

Just wanted to get the lists opinion on this. 
We have RAID 5 for several of our servers. However, our database server
is going to be rebuilt and I have read several articles saying that RAID
5 is not a good choice for a DB server. What would you guys recommend
for a DB Server?

What's keeping you from getting more from your terminal servers? Did you know, 
in most cases, CPU Utilization IS NOT the single biggest constraint to scaling 
up?! Get this free white paper to understand the real constraints & how to 
overcome them. SAVE MONEY by scaling-up rather than buying more servers.
