Description
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 mode offers superior performance and protection by striping data
across 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 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.
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.
Data is striped across multiple hard drives, enabling accelerated
reading and recording of data by combining the work of two or
more drives to increase performance.
However, If one drive fails, all of your data will be lost.
