RAID Configurations: RAID 1+0

RAID 1+0
A RAID 1+0 (also known as RAID 10) is a striped array with segments consisting of RAID 1 arrays. RAID 1+0 has the same fault tolerance as RAID level 1 plus the overhead fault-tolerance of mirroring. RAID 1+0 requires a minimum of 4 hard drives to configure.

In some installations, a RAID 1+0 array can recover from multiple and simultaneous hard drive failures. RAID 1+0 is typically used in database server applications, such as an Exchange Server or SQL database server, which requires high performance and high fault tolerance levels because of the limited scalability and high inherent costs to operate a RAID server configured this way.
