There were originally five different RAID levels. However, you can use a number of hard drives to create more raid levels, although this may affect performance.
Raid Levels are determined by MTTF/number. To determine the raid levels one should reference the standard raid levels and determine what raid level your data storage capacity needs.
RAID provides two main advantages: space and data security
The actual level used is not as important as what use the server is intended for. Different levels of RAID are used for different applications. They can include mirroring and striping.
an industrial standard which exist for multiple-disk database schemes, is termed as RAID. The basic strategy used in RAID is to replace the large capacity disk drive with multiple smaller capacity disks. there are several RAID levels. RAID 0 is for striping: Applications requiring high performance for non critical data. RAID 1 is for Mirroring : (Typical applications) System drives; critical files. ther are 6 RAID levels may be its in the form of disks overlaping one upon the another. With this background can any one give detailed, pictorial form of RAID Thank you, Suman (MCA student)

The answer depends on whether one is looking to configure RAID via hardware or software. Windows is capable under disk management to run RAID via software. The first step is to convert to a dynamic disk. Then the RAID levels supported, in parentheses are Striped, 2 disks (0) Mirrored, 2 disks (1) Striped with parity, which required 3 disks (5) being the three most popular. That said if RAID is being done at the hardware level, then the operating system is oblivious to the fact that it is being raided at all and simply reads what the RAID controller tells it to. In this scenario all RAID levels are suported. For a deeper discussion on raid levels the following site is excellent. http://www.acnc.com/04_01_00.html

It depends on what RAID level you are planning to use. One of the most common levels is RAID 1, data is written identically to multiple hard drives. This achieves redundancy in a RAID system. It creates a duplicate, a fail safe in case of a hard drive failure.
