- RAID mode of MAIWO K8AA machine: NORMAL, BIG LARGE, RAID 0*2, RAID 0,
PM, LARGE*2, RAID 5*2, RAID 5*0, etc.
- The initial state of the product is NORMAL (Clear RAID) mode, please do change
to NORMAL mode before setting other RAID modes.
* Important Notes
- When using RAID configuration, it is recommended that the manufacturer,
model number and capacity of hard disks are the same.
- When using RAID configuration, all data on the hard disks will be deleted, and
the data must be backed up before use.
- Please turn off the power switch before setting RAID mode via switch.
- After RAID mode switch is set, press RESET button and hold on and then turn
on the power switch, release the RESET button after about 15 seconds, the
setting will be successful.

Please change to NORMAL mode first before setting any other RAID modes.
Normal BIG LARGE RAID 0 *2 RAID 0
PM LARGE *2 RAID 5 *2 RAID 5+0

RAID 0, also known as Stripe or Striping, is a method of combining the capacity
of more than 2 hard drives into a single volume. And when data is recorded,
data is logged to each hard drive separately. Each hard disk displays different
data results, records or reads data at the same time, and the transfer speed is
fast, which can significantly improve the overall disk access performance.
But when there is a problem on one hard disk, other data on different hard
disks also disappears, and the data stability is poor.
Application of RAID 0 mode: RAID 0 mode can be used when large-capacity,
high-speed data storage is required.

RAID0*2 minimum four disks, can set two groups of RAID0 at the same time, to

in the data recording data will be recorded to each hard disk separately, each
hard disk displays different data results, while recording or reading data, the
transfer speed is fast, can significantly improve the overall access performance
of the disk. But when there is a problem on one hard disk, other data on differ-

Delete previous RAID mode and reselect the new RAID mode. At the same
time, the hard disks are in a normal and independent state, and they can write
or read data independently, and the actual capacity that can be used is the
capacity of 4 hard disks. If one of the drives is damaged, the other drives will
not be affected.

With a minimum number of 3 hard drives, parity information on one drive will
be spread across all drives.
RAID 5 can be understood as a compromise between RAID 0 and RAID 1, with
RAID 0 data read speed, but with an additional parity information, the speed of
writing data is slightly slower than writing to a single hard disk.
When a hard disk data is corrupted, the remaining data and the corresponding
parity information are used to recover the corrupted data.

The hard disk capacity is simply added together, turning several hard disks
into one hard disk, the capacity is the sum of the capacities of several hard
disks, and the maximum hard disk space can be obtained in this mode.
The hard disk capacity is simply added, several hard disks are turned into one
hard disk, and if 8 disks are full, the setting mode can produce two 4 disk
capacity plus volumes.

OS operating system such as 32bit Windows XP/2000 only supports MBR
format, so hard disks using this method can only reach 2TB.
(Usage Example)
Two pieces of 2TB hard drives with RAID 0, JBOD mode setting. (MBR Format)
2TB (2048.00GB), the remaining 1678.03GB is unusable.
