Is all the raid levels are covered in one concept.... or their are different concepts behind each level...

In computing, the acronym RAID (originally redundant array of inexpensive drives (or disks), also known as redundant array of independent drives (or disks)) refers to a data storage scheme using multiple hard drives to share or replicate data among the drives. Depending on the configuration of the RAID (typically referred to as the RAID level), the benefit of RAID is to increase data integrity, fault-tolerance, throughput and/or capacity, compared with single drives. In its original implementations, its key advantage was the ability to combine multiple low-cost devices using older technology into an array that offered greater capacity, reliability, speed, or a combination of these things, than was affordably available in a single device using the newest technology. http://en.wikipedia.org/wiki/Redundant_array_of_independent_disks

RAID levels are used to describe different methods by which data is spread across multiple disks.
RAID is actually an acronym for "redundant array of independent (or inexpensive, if you're old school) disks"
Data that would normally be put on one drive, is spread across multiple disks that act as one.
Different levels have different functions.
RAID-0 will spread data across multiple disks, but doesn't provide redundancy if one of them fails. So with that you can combine two 100gb disks to be a single 200gb, but you lose everything if one of them fails.
RAID-1 will mirror two or more disks, the downside is that you get half the disk space. If you buy two 100gb drives, you will only have 100gb because the second drive is used only to be copy of the first.
RAID-5 will spread data across at least 3 disks, and if one fails, your data will be safe.
There are a lot of others, too. if you go to en.wikipedia.org and look up RAID, there is a good explanation of each.

There are seven official levels of RAID, numbered 0 - 6
RAID 0- Disk striping
RAID 1 - Disk mirroring and disk duplexing
RAID 2 - Disk striping with multiple parity drives.
RAID 3 and RAID 4 - Disk striping with parity> The differences between the two are trivial
RAID 5 - disk striping with parity, where parity info is placed on all drives. This is the most common RAID implementation on server machines.
RAID 6 - RAID 5 with the added capability of asynchronous and cached data transmission. (Super RAID)
Different concepts behind each level

specific there's a hellish raid occurring in R&S. that's a hellish "panty raid". purely observed bonsai bobby sneaking out of your back door with crimson satin underclothes on his head. Yep, blame it on the complete moon.

Here is a GREAT article about raid setups. http://en.wikipedia.org/wiki/Redundant_array_of_independent_disks
