Redundant array of independent disks (RAID), is a method of storing duplicate data on two or more hard drives. It can achieve redundancy, fault tolerance, lower latency, increased bandwidth, and maximized ability to recover from hard disk crashes. Traditional RAID 5 technology supports the recovery of performance when a single hard disk crashes, but if more than two hard disks crash, data will be lost.
Hikvision VRAID technology supports D+P (Double Parity) configuration, which guarantees data recovery capability by configuring multiple redundant disks for stable video storage. In general, VRAID is set to not lose video when 1-2 disks are damaged, and the maximum support can be up to 4 disks are damaged and still not lose video.

In the case of abnormalities (dropped disks, damaged disks, etc.) of hard disks exceeding the number of fault-tolerant disks, it can continue to run on normal disks as long as normal disks still exist in the RAID group.
Read: If the number of fault-tolerant hard disks is exceeded, the data of the remaining available hard disks can be read, even if only a portion of the information is available, partial data reading is possible.
Write: For new video recordings, it can still continue to write to the normal hard disk even if there is only one available hard disk left, ensuring business continuity.

For long-period storage, customers want to ensure that even if the hard disk is damaged, the video recording can still continue to work. Typical scenarios such as factories, buildings.
