RAID Mode Introduction
RAID 3 - Mirroring/Striping:
RAID 3 provides the ability to read/write data on multiple disks. This facilitates fast data
transmission and creating a duplicate (mirrored) copy of the last HDD. During operation,
when one HDD is busy, the other HDD disks can be read for quicker data access. This
RAID mode adds great security in that should one HDD fail, the system can automatically
switch to the mirrored HDD to read/write. Simply replace the failed HDD with a new one
(equal or greater capacity), and the RAID mode will rebuild the data onto the new HDD.
RAID 5 - Mirroring/Striping:
RAID 5 provides the ability to read/write data on multiple disks that facilitates fast data
transmission and creating a duplicate (mirrored) copy of the data that is distributed
throughout the disks. During operation, when one HDD is busy, the other HDD disks can be
read for quicker data access. This RAID mode can also automatically switch to the mirrored
data if one HDD fails and rebuild the system can automatically by replacing the failed HDD.
RAID 3 and RAID 5 both use the performance of Striping (RAID 0) and the security of
Mirroring (RAID 1), which enhance HDD stability and data security.
