The VIA RAID Controller Windows driver is a software package that allows Windows to interact with a VIA Technologies RAID controller. RAID stands for Redundant Array of Independent Disks, and a RAID controller manages multiple storage drives to create a single logical volume that can provide improved performance, redundancy, or both, depending on the RAID level (e.g., RAID 0, RAID 1, RAID 5, etc.).
VIA Technologies manufactures a variety of RAID controllers, often used on motherboards with integrated RAID functionality or in discrete expansion cards. The VIA RAID Controller driver allows the operating system to recognize and manage these controllers, enabling features like disk array management and RAID configurations.
