(1) Step 1: Configure Volume
Here you can configure the new RAID volume by entering the volume name,

RAID Volume Name:
A desired RAID volume name needs to be typed in where the 'RAID_Volume1' text

you with a realtime duplicate copy of your data. Note:
Only half of the available volume space will be avail-
able for data storage.
RAID 5 can be used on three or more disks, with zero
or more spare-disks. The resulting RAID-5 device size
will be (N-1)*S, where N is the how many drive, S is the
size of the smallest drive in the array. If one of the disks
fail, all data are still intact. It can rebuild the disk from
the parity information. If spare disks are available, re-
construction will begin immediately after the device
failure. If two disks fail simultaneously, all data are lost.
RAID-5 can survive one disk failure, but not two or
more. Both read and wri te perf ormanc e us ually
increase, but can be hard to predict how much. Reads
