Options include:
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.
RAID 1 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.
RAID 5 RAID 5 mode offers superior performance and protection by striping data
ac
ross 3 or more drives and dedicating a quarter of each drive to fault
tolerance.
This option is only available for 4-bay My Cloud devices.
RAID 10 RAID 10 mode is a RAID protocol in which data is written in stripes across
primary disks that have been mirrored to the secondary disks.
This option is only available for 4-bay My Cloud devices.
JBOD The use of one or more drives not in a RAID configuration but
m
anaged as separate logical volumes.
Spanning Combination of drives in a linear fashion to create one large
logical vol
ume.
