RAID Modes
RAID Type
Requires at least 2 drives. Available capacity is equal to the total capacity of all member hard drives.
JBOD
No data redundancy is provided.
If any drive fails, all of the data cannot be restored.
Requires only 1 drive. Available capacity is equal to the capacity of the hard drive.
Basic
No data redundancy is provided.
If the hard drive fails, all of the data cannot be restored.
Requires at least 2 drives. Available capacity is equal to the total capacity of all member hard drives.
In RAID 0, data are divided into blocks and split across multiple drives; therefore, theoretical read/write
RAID 0
speed is n times that of a single drive. (n means the number of the hard drives)
If any drive fails, all of the data cannot be restored.
Requires at least 2 drives. In RAID 1, data are mirrored on all drives.
The volume of the smallest member drive determines the total capacity of the storage pool.
RAID 1
If the number of failed hard drives does not exceed 1, the lost data can be restored by replacing the
failed hard drive.
Requires at least 3 drives.
The total capacity of a RAID 5 group is equal to (number of hard drives-1) × volume of the smallest
RAID 5
member drive.
If the number of failed hard drives does not exceed 1, the lost data can be restored by replacing the
failed hard drive.
Requires at least 4 drives.
RAID 6 features an extra drive to store parity information based on the RAID 5.
The total capacity of a RAID 6 group is equal to (number of hard drives-2) × volume of the smallest
RAID 6
member drive.
If the number of failed hard drives does not exceed 2, the lost data can be restored by replacing the
failed hard drives.
Requires at least 4 drives, and the total number of hard drives should always be an even number to
create a storage pool.
The total available capacity of a RAID 10 group is equal to (number of hard drives/2) × volume of the
RAID 10
smallest member drive.
If the number of failed hard drives does not exceed 2, the lost data can be restored by replacing the
failed hard drives.
Tip
· In JBOD storage mode, the failure of a single hard drive results in storage failure for all drives.
· The capacity of new hard drive that used to replace the failed drive must be larger than the capacity of the smallest
drive in RAID 1/5/6/10 storage configurations.
· When the number of failed hard drives exceeds the allowable number in the selected mode, all data in the corresponding
storage pool will be lost and cannot be restored.
· It is recommended for beginners to start with the RAID 5 mode. An appropriate RAID mode can be selected later
based on preferred needs.
Notice!
If the system prompts you to format the hard drive when configuring storage space, please back up all the important
data in advance. After formatting, all data in the storage space will be removed and cannot be restored.

When the NAS device is turned on, use a pin-like object to inser t and hold the "RESET" hole for
5 seconds until you hear the buzzer beeping. The device will not restar t during the reset
process. Af ter the reset is complete, the solid white net work indicators will turn on, indicating
that the device is ready for use.
Please note that the reset will not af fect the data stored in the hard drive. Af ter successful
reset ting, you can log in to the system with the "admin" account and blank password (this
account is specifically utilized for password resets). Once logged in, follow the step-by-step
wizard to configure your administrator password.
