.Sh SUPPORTED RAID LEVELS
The GEOM RAID class follows a modular design, allowing different RAID levels
to be used.
-Support for the following RAID levels is currently implemented: RAID0, RAID1,
-RAID1E, RAID5, RAID10, SINGLE, CONCAT.
-RAID5 support is read-only and only for volumes in optimal state.
