RAID Configurations: RAID 0

RAID 0
A RAID 0 configuration is a striped array without fault tolerance. It requires a minimum of 2 hard drives to configure. If any hard disk in this configuration fails, the entire RAID volume will be lost completely.

Because of the severity of type of data loss, a RAID 0 configuration should not be utilized for any database server which contains sensitive information, such as an Exchange server or SQL server. The benefit to this type of RAID configuration is that it requires at least 2 hard drives to be used.

Did You Know?

Formatting a boot drive or partition can also damage or remove striping, which reduces the recoverability of data and causes permanent loss.

Common Causes for
RAID Failures

• Adding incompatible hard drives to the RAID array.
• Hardware conflicts with the hard drive and RAID server.
• Software corruption to the operating system.
• A virus infection, software or operating system upgrade.
