RAID Controller
A RAID controller is a hardware device that manages multiple hard drives or SSDs in a computer system. Its main role is to coordinate data storage across these drives, improving performance, data security, or both. By controlling how data is written and read, the RAID controller can set up different configurations—such as mirroring data for safety or spreading data across drives to boost speed. It functions either as a dedicated card installed in the server or integrated into the motherboard, ensuring efficient and reliable management of multiple storage devices.
