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

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.
