Hello，

Raid 1 performance: both hard drives have the same data；

One hard disk is the direct visible hard disk capacity, and the other hard disk is equivalent to the mirror hard disk. The data is written at the same time. When the visible hard disk is damaged, the mirror hard disk will automatically restore the complete data to the hard disk.

About software operation, you can get more information on google.

Best regards
