Generally, the hard disks save/access data by internal mechanical operation, such as motors and magnetic reader heads that eventually might cause data loss, due to the head and platter consumption or corruption for the long-time accessing.

Accudual follows the mirroring RAID 1 disk array technology to develop a series of real-time data backup system. by the Dual hard disk, the data saved on hard disk is real-time backup to the other array member disk, it reduces the risk of system from when single hard disk is damaged and result in data loss.
