Mode
Description
RAID 0
(Striping)
Striping combines multiple disks into a single large disk array.
The data is split evenly across each disk simultaneously. Read/
write performance is increased as a result, but failure of any one
disk will make the entire array unusable.
RAID 1
(Mirror)
Mirroring writes the same data across multiple disks, creating
exact mirror copies. This provides redundancy in case one drive
fails.
JBOD
(Single)
JBOD enables each hard drive to be seen as separate
independent drives. If only a single hard drive is installed,
ensure this mode is enabled.
NOTE:
When using eSATA, this mode should only be used if the
eSATA host controller provides Port Multiplier (PM) support. If a
host is not PM-aware, only a single drive will be visible. No such
limitation exists if using the USB connection.
BIG
(Concat)
BIG concatenates multiple hard drives into a single large disk.
Provides no performance or redundancy benefits.
