The ATI 4379 SATARaid Controller Windows driver refers to the software that allows Windows operating systems to properly recognize and interact with the ATI 4379 SATA RAID Controller. This controller is typically used to manage multiple hard drives in a RAID (Redundant Array of Independent Disks) configuration, providing data redundancy or improved performance by combining multiple drives into one logical unit.

The ATI 4379 is a part of the ATI (now part of AMD) family of SATA RAID controllers, which are often integrated into motherboards or used as standalone PCIe cards. These controllers provide support for RAID levels like RAID 0, RAID 1, RAID 5, and RAID 10, as well as for individual drives (AHCI mode).
