Raid Storage - Western Digital My Cloud EX2 Ultra User Manual

RAID Storage

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 My
Cloud EX2 Ultra device allows you to select from the following storage modes:
RAID Mode
JBOD
Spanning
RAID 0
RAID 1

USER MANUAL
Description
The use of one or more drives not in a RAID configuration but managed as
separate logical volumes.
Combination of drives in a linear fashion to create one large logical volume.
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 levels. RAID 0 breaks up data into smaller segments
and stripes the data segments across each drive in the drive group.
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.
