2 RAID Modes & DIP Switch
A RAID mode formed by RAID 0 read & write speed + RAID 1 safety.
Two disks form a RAID 1, then two sets of RAID 1 form a RAID 0.
When two disks fail at the same time but they're not in the same RAID 1, then the data can still be readable.
Best security, average read and write speed and smallest available capacity.
Take the min. capacity disk as the main one, then clone data to the other disks, all of the disks share the same
data. When one disk fails, all the others will not be affected.
Largest available capacity, average read and write speed, and low security.
All hard drives form a big drive, when one of them fails, all of your data will be unrecoverable.
Default factory setting mode, all disks work separately.
When one disk fails, all the others will not be affected.

Fastest read and write mode, largest capacity but low security.
When one of the hard drives fails, all of the data cannot be restored.
High security, acceptable read and write with small capacity.
When one hard drive fails, other drives work normally; then you'll have to replace the broken drive (greater than or
equal to the capacity of the original capacity), all of your lost data will be recovered automatically.
For fast read & write altogether with security & capacity.
Set one disk as the parity disk, and all the other data disks.
When one data drive fails, the original data can be recovered by making use of the remaining data and the parity
info. When two drives fail at the same time, all of the data will be unrecoverable.
For fast read & write altogether with security & capacity.
Data and parity info are restored respectively on different disks, and data and its corresponding parity info are on
different drives.
When one of the drives fails, the original data can be recovered by making use of the remaining data and the parity info.
When two drives fail at the same time, all of the data will be unrecoverable.
