Description
Each hard drive is used as a standalone
disk. If a hard drive is damaged, all the data
will be lost.
JBOD is a collection of hard drive that does
not offer any RAID protection. The data are
written to the physical disks sequentially.
The total storage capacity is equal to the
sum of the capacity of all member hard
drives.
RAID 0 (striping disk) combines 2 or more
hard drives into one larger volume. The data
is written to the hard drive without any parity
information and no redundancy is offered.
The total storage capacity of a RAID 0 disk
volume is equal to the sum of the capacity of
all member hard drives.
RAID 1 duplicates the data between two
hard drives to provide disk mirroring. To
create a RAID 1 array, a minimum of 2 hard
drives are required.
The storage capacity of a RAID 1 disk
volume is equal to the size of the smallest
hard drive.
