The video recorder supports software-based disk arrays. Enable the RAID function as required, and ensure each HDD capacity is not less than 4 TB. If your device has no more than 16 SATA interfaces, a disk array can contain no more than 8 HDDs. If your device has 24 SATA interfaces, a disk array can contain no more than 12 HDDs. Two ways are available for creating an array: one-touch configuration and manual configuration.
