SCSI (Small Computer System Interface) and RAID (Redundant Array of Independent Disks) controllers are storage controllers used to manage SCSI and RAID devices, respectively. SCSI controllers provide connectivity and communication between SCSI devices such as hard drives, tape drives, and optical drives and the computer system. RAID controllers, on the other hand, implement RAID configurations to improve data reliability, availability, and performance by distributing data across multiple disks. These controllers are commonly used in servers, workstations, and storage arrays to enhance storage performance and reliability.
