Technically, it's a volume spanning driver which supports
mirroring. It has also been used (by Rod Grimes) with
spindle sync to support true striping.
Without parity, ECC, or hamming codes, it's not real RAID.
Without parity, ECC, or hamming codes in software, it's a hell
of a lot faster than real software RAID would be.
If you want RAID, there are several hardware RAID implementing
SCSI contreollers, like the Compay RAID SCSI controller, for
which driver software is available for some of the BSD derived
OS's.
