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 WD My Cloud EX4 server
allow you to select from the following storage modes:
RAID Mode Description
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 levels. RAID 0 breaks up data into smaller segments and stripes the
data segments across each drive in the drive group.
