EPHD04+ HDcctv DVR
6.7.3RAID
The RAID function (Redundant Arrays of Independent Disks) can enable two hard disks to act as one, allowing users to achieve data redundancy (RAID 1) or greater effective disk speed (RAID 0).
Note: It is recommended to use two HDDs with the same capacity. Otherwise, the smaller size will be the amount of disk space used on both drives. For example, if HDD1 is 200 GB and HDD2 is 500 GB, and RAID 0 is selected, the total amount of disk space recognized by the DVR will be 400 GB (200 GB + 200 GB).

Local Drive Configuration
RAID 0: RAID 0 is designed to improve disk speed. Data is written to two disks alternatively, instead of just one, which improves the overall system speed. Note that if the two HDDs are with different capacity, the smaller size will be the amount of disk space used on both drives.
RAID 1: RAID 1 is designed for disk redundancy. The same data is written to two disks. When one hard disk fails, the other hard disk contains all the data. Note that if the two HDDs are with different capacity, the smaller size will be the amount of disk space used on both drives.
