RAID 10 IS RAID 1 + RAID 0, i.e., a mirrored set of striped sets.  This is completely standardized in the RAID vernacular, although it is occasionally written as RAID 1+0.  Similarly, you can have RAID 0+1, which is a striped set of RAID mirrors (and, therefore, FAR less common than RAID 10, which is a relatively common way of protecting large striped sets.)
