the second drive is used to automatically receive the data of the first. Mirroring

BE CAREFUL : MIRRORING (RAID 1) is not a back-up system. Do not forget to
back-up your data. In case of data corruption, directory erase, undesired file save,
the RAID 1 function is of no use. If you write corrupted data to the first disk,
RAID 1 system is also writing the corrupted data to the second drive.
- RAID 0 Striping disk Volume
RAID 0 (Striping disk) combines 2 drives into one larger disk. It offers the fastest
disk access but it does not have any protection of your data in the striped array
fails. The disk capacity equals the double of the capacity of the smallest of the
two drives
- Linear disk Volume
You can combine two or more disks into one larger disk. During file saving the file
will be saved on physical disks sequentially but does not have a disk failure file
protection function. The overall capacity of linear disk is the sum of all disks.
Linear disk is generally used for storing large data and is not appropriate to use
for file protection of sensitive data.
