The type of mirroring supported on the media vault is called Redundant Array of Independent Disks (RAID) RAID-1.

In RAID-1 mirroring, an identical copy of data written to a volume on one hard disk is written to a volume on a second hard disk. Mirroring volumes reduces your total hard disk storage capacity by half. The advantage is that if one hard disk fails, you have a copy of your data on the second hard disk.

Disk Concatenation

Disk concatenation (also called JBOD) is another type of advanced storage configuration. This type of configuration combines the available space from two or more hard disks into one large logical volume.
