Which of the following are attributes of a hardware-based RAID controller? (Select THREE).

RAID provides data redundancy and availability, protecting against drive failure, but it is not a backup solution for protecting against data corruption or accidental deletion.

Hardware RAID controllers are generally more expensive than software RAID solutions due to the dedicated physical hardware and advanced features they include.

Hardware RAID implementations are specific to the vendor of the controller, making them proprietary rather than vendor-neutral.

Hardware RAID controllers typically integrate a dedicated BIOS or UEFI interface that allows users to configure and manage RAID volumes before the operating system initializes.

Hardware RAID controllers have their own dedicated processor to perform RAID calculations, which offloads processing tasks from the host CPU, resulting in less host CPU usage compared to software RAID.

After the operating system has loaded, hardware RAID controllers provide dedicated management utilities or command-line interfaces for monitoring and reconfiguring the RAID arrays.

Many hardware RAID controllers are equipped with a battery-backed cache (BBWC) or non-volatile cache which can temporarily store data during a power outage, preventing data loss until power is restored or data is written to disk.
