RAID is an acronym for Redundant Array of Inexpensive (or Independent) Disks. A RAID array is a collection of drives which collectively act as a single storage system, which can tolerate the failure of a drive without losing data, and which can operate independently of each other. What are the different RAID levels? A research group at UC-Berkeley coined the term “RAID”, defining six RAID levels. Each level is a different way to spread data across multiple drives–a compromise between cost and speed. Understanding these levels is important, because each level is optimized for a different use. RAID Level 0 RAID Level 0 is not redundant, hence does not truly fit the “RAID” acronym. In level 0, data is split across drives, resulting in higher data throughput. Since no redundant information is stored, performance is very good, but the failure of any disk in the array results in data loss. This level is commonly referred to as striping. RAID Level 1 RAID Level 1 provides redundancy by dupli
