This means that you have far more flexibility with striped sets of mirrored sets than you do with RAID-10 arrays. The data in a striped set of mirrored sets is redundant, like the data in a RAID-1 array. The NetRAID-4M also allows for the creation of a volume set of mirrored sets . A volume set of mirrored sets is a multilevel container that is a concatenation of one or more mirrored sets. Once again, the data is redundant, but unlike the striped set of mirrored sets, the volume set will fill one mirrored set before moving on to the next one.
M allows for the creation of a volume set of striped sets .
A volume set of striped sets is a multilevel container made up of one or more striped sets. As data is written to the volume set of striped sets, it will be written to the first striped set first. Then, subsequent writes will be directed to the next striped set. It is a combination of RAID levels 3 and 0. It also uses dedicated parity drives, just as RAID-3 does.
