Single Disk Volume

Each hard drive is used as a

standalone disk. If a hard drive is

damaged, all the data will be

lost.

JBOD (Just a bunch of disks)

JBOD is a collection of hard

drives 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 Volume

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
