Some vendors have also implemented another slight variation of RAID-1 and
refer to it as RAID-10 since it combines features of RAID-1 and RAID-0. Others
refer to this technique as RAID-6, which is the next available RAID level.
As shown in Figure 15, this solution consists of mirroring a striped (RAID-0)
configuration. In this example, a RAID-0 configuration consisting of 2 drives
(drive 1 and 2) is mirrored to drives 3 and 4.

Performance and capacity are similar to RAID 1. 50% of total disk capacity is
usable. However, this solution always uses an
even
number of disks. RAID-1
enhanced can use an
odd
number of disks. RAID-1 also can be mixed with
others RAID levels.
