What is difference betweev mirroring and striped technique?

Striping technique
Striping technique provides high performance for RAID configuration. In striping technique data is interleaved at all the hard drives.

Mirroring Technique
Mirroring technique is a technique in which data is written simultaneously to each hard drive as an image for data security. It behaves like duplicate data on other drive.

Level 0: Striping
--- Level 0 provides increased performance by writing alternating blocks of data (referred to as the stripe size) to 2 or more drives simultaneously. Read performance is also improved since data is read from all drives at the same time. No redundant information is stored and failure of a SINGLE drive will cause all data to be lost. The number of drives in a level 0 array is sometimes also referred to as the stripe width.

Level 1: Mirroring.
--- Level 1 provides redundancy by writing all data to 2 or more drives. Level 1 provides no increase in write performance (it may even be a bit slower). Read performance tend to be faster than a single drive, but not as fast as level 0. Level 1 provides excellent data security since ALL drives has to fail before any data is lost.

Mirroring is a technique in which data is written simultaneously to two or more hard disks,even if one hard disk fails, the computer automatically accesses to next hard disk without the loss of data. On the other hand, Stripping is used for interleaving the data for all the hard disks. It provides the best performance for RAID Configuration.
