CMS enables you to build a system with RAID 10 performance and redundancy. Having such redundancy reduces the risk of data loss should a disk drive fail or your system crash.

While RAID 10 greatly reduces the risk of losing data, it is not meant to be a substitute for regular backups. Data can still become corrupt, and the corruption is then duplicated on the mirror.

In addition, RAID 10 enables for better performance by writing data across multiple disks. CMS RAID support is enabled through an internal RAID controller.
