On the software-defined storage side, Gluster offers "dispersed volumes" which offers 1.5x cost for replication via erasure coding on JBOD (instead of the 2x cost for RAID1 replication). One benefit of gluster is that you can also setup a geo-replicated off-site destination which can act as a backup.
