RAID 0 Concatenation/Striping
RAID 1 Mirroring
RAID 5-Striped array with rotating parity.

Concatenation: Concatenation is joining of two or more disk slices to add up the disk space. Concatenation is serial in nature i.e. sequential data operations are performed serially on first disk then second disk and so on. Due to serial nature new slices can be added up without having to take the backup of entire concatenated volume, adding slice and restoring backup.
Striping: Spreading of data over multiple disk drives mainly to enhance the performance by distributing data in alternating chunks - 16 k interleave across the stripes. Sequential data operations are performed in parallel on all the stripes by reading/writing 16k data blocks alternatively form the disk stripes.
Mirroring: Mirroring provides data redundancy by simultaneously writing data on to two sub mirrors of a mirrored device. A submirror can be a stripe or concatenated volume and a mirror can have three mirrors. Main concern here is that a mirror needs as much as the volume to be mirrored.
RAID 5: RAID 5 provides data redundancy and advantage of striping and uses less space than mirroring. A RAID 5 is made up of at least three disks, which are striped with parity information written alternately on all the disks. In case of a single disk failure the data can be rebuild using the parity information from the remaining disks.   _{Your Comment}
