Allowed
Failed HDD #
The system will write identical data to each hard
(HDD #) - 1 drive at the same time, so data integrity is
protected when at least one disk is normal.
This configuration includes a backup option. It
uses parity mode to store redundant data on
1
space equal to the size of one disk for later data
recovery.
A RAID 5+Spare storage space requires at least
four drives, one of which will act as a hot spare
2
drive to rebuild the failed drive of the volume
automatically.
RAID 6 provides extra data protection. It uses
parity mode to store redundant data on space
2
equal to the size of two disks for later data
recovery.
RAID 10 has the performance of RAID 0 and data
1 HDD within
protection level of RAID 1. RAID 10 combines two
each RAID 1
hard drives into a RAID 1 group, and combines all
group
the groups with RAID 0.
