Managing Storage on WD My Cloud Mirror 

The Storage page allows you to configure the storage within your device and view the status 
and capacity of its disks. This chapter provides details on managing the storage on your WD 
My Cloud Mirror device.

RAID (Redundant Array of Independent Disks) allows you to store the same data in different 
places on multiple hard drives, providing necessary redundancy, greater performance, and 
data integrity. There are several different levels of RAID, each one providing a different 
method of sharing or distributing data among the drives. Your WD My Cloud Mirror device 
allows you to select from the following storage modes:

Note:  The difference between a drive and a volume is that a volume can be a 

single drive or multiple drives. 

JBOD

The use of one or more drives not in a RAID configuration but managed as 
separate logical volumes.

Spanning

Combination of drives in a linear fashion to create one large logical volume.

RAID 0

RAID 0 mode provides disk striping across all drives in the RAID drive group. 

 

RAID 0 does not provide data redundancy but does provide the best performance 
of any RAID level. RAID 0 breaks up data into smaller segments and stripes the 
data segments across each drive in the drive group.

RAID 1(default)

In RAID 1 mode, the RAID controller duplicates all data from one drive to a second 
drive in the drive group. RAID 1 provides complete data redundancy but cuts the 
required storage capacity in half.
