The Intel(R) RS HW Recovery driver, or Intel Rapid Storage Hardware Recovery driver, is a software component that typically relates to Intel's Rapid Storage Technology (RST). Intel RST is designed to manage storage devices such as hard drives (HDDs) and solid-state drives (SSDs), and it offers features like RAID (Redundant Array of Independent Disks), AHCI (Advanced Host Controller Interface), and hot-swap support.
The RS HW Recovery part of the driver is specifically related to providing support for hardware-level recovery in the event of drive failures, typically within RAID configurations. It helps to ensure data recovery and RAID array recovery in cases where a disk fails or an error is detected. It may be required when you have a RAID setup or are using Intel's advanced storage solutions.
