I am just referring to how few of them bolden it out in their plans and others have no mention.
What are advantages of RAID drive?
RAID - Redundant array Independent Disks
There are three primary reasons that RAID was implemented:
* Increased Performance
* Lower Costs
Redundancy is the most important factor in the development of RAID for server environments. This allowed for a form of backup of the data in the storage array in the event of a failure. If one of the drives in the array failed, it could either be swapped out for a new drive without turning the systems off (referred to as hot swappable) or the redundant drive could be used. The method of redundancy depends on which version of RAID is used.
The increased performance is only found when specific versions of the RAID are used. Performance will also be dependent upon the number of drives used in the array and the controller. Like RAID 1 , 3 , 5 and 10
Though you are having RAID implemented you should have a back up solution in order to save your valuable data.
