About Storage
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 My Cloud
device.
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 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.
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 level. RAID 0 breaks up data into smaller segments
and stripes the data segments across each drive in the drive. group.
