What Is RAID 0, 1, 5, 10?

RAID is an acronym for Redundant Array of Independent Disks. With RAID enabled on a storage system, you can connect two or more drives in the system so they act as one large volume fast drive. Or, you can set them up as one system drive used to automatically duplicate (or mirror) your data for real-time backup.

Provides disk striping across all drives in the RAID drive group. RAID 0 can't provide data redundancy but can provide the best performance of any RAID level. It breaks up data into smaller segments and stripes the data segments across each drive in the drive group.


Sets the system to data protection mode and the capacity is divided in half. Half of the capacity is used to store your data and half is used for a duplicate copy. If one drive goes down your data is protected because it's duplicated.


Gives you the best of both advantages: fast performance by striping data across all drives; data protection by dedicating a quarter of each drive in a four-drive system to fault tolerance leaving three-quarters of the system capacity available for data storage.


Delivers very high I/O rates by striping RAID 1 (mirrored) segments. This RAID mode is good for business-critical database management solutions that require maximum performance and high fault tolerance. A system set to RAID 10 yields half the total capacity of all the drives in the array.
