What is hardware RAID?

 For hardware RAID, all drives are connected to a hardware RAID controller, which can be located on a separate RAID card, on a different server or built into the motherboard. The hardware RAID controller manages the RAID array, configures and supports multiple RAID levels. It contains a microprocessor (often called an I/O processor, or ROC ‘RAID on Chip’). In some cases, RAID controllers with their own processors can act as mini-computers because they have the ability to perform tasks independently.

During the hardware RAID installation process, the drive is connected to the RAID controller board. This applies not only to large servers, but also to desktop computers. Processing hardware RAID refers to discrete controllers at the disk storage system level (such as ATA RAID, SATA, DELTA PLC, etc.).
PROS： Will not occupy or affect the performance of the computer or server; Compatible with different operating systems; Prevent data damage due to power outage during the backup process; It is easy to replace a failed disk.
CONS: The cost is higher than software RAID; If your RAID controller fails, you must find a compatible RAID controller to be replaced.
