Non-RAID mode:
When the system is in the non-RAID mode, recorded files will be automatically dispatched to every hard disk sharing the read/write bandwidth.

Note:
SATA 1~4 belong to Group 1 while SATA 5~8 belong to Group 2. When you install the hard disks, please install them according to the group in pairs for the best read/write performance.
For example:
2 HDDs: SATA1 , SATA5
4 HDDs: SATA1 , SATA5 , SATA2 , SATA6
8 HDDs: SATA1 ~ SATA8
