What Is a RAID Array?

[datarecovee]

If you're thinking about what a RAID array is, it is basically a collection of physical storage drives that are configured to operate as one logical storage array. Based on the chosen configuration, the RAID array could enhance the performance of a computer, offer some redundancy, or do both. The data could be written using striping across several drives, mirroring between drives, or including parity information so as to reconstruct the data from failed drives. Some of the most common types of RAID include RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10. Each of these types has its own demands in terms of number of drives, usable space, performance, and redundancy.
