The combination of a mirrored configuration with striping added is referred to as RAID 1+0 (also called RAID 10). In this scenario, the configuration will provide mirroring (RAID 1) across two (2) or more drives and will “stripe” the data in real-time to a second mirrored drive set. This unique combination will provide data redundancy and some speed advantages, but it does so at the expense of usable storage space. A volume established as a RAID 1+0 volume provides a little more data protection than a RAID 0+1, and will need four (4) hard drives at a minimum to be configured.
