There are many different ways to organize data in a RAID array. These ways are called "RAID levels". Different RAID levels have different speed and fault tolerance properties. RAID level 0 is not fault tolerant. Levels 1, 5, 6, and 1+0 are fault tolerant to a different degree - should one of the hard drives in the array fail, the data is still reconstructed on the fly and no access interruption occurs.
RAID levels 2, 3, and 4 are theoretically defined but not used in practice.
There are some more complex layouts: RAID 5E/5EE (integrating some spare space), RAID 50 and 60 (a combination of RAID 5 or 6 with RAID 0), and RAID DP. These are however beyond the scope of this reference.
