is a Windows driver related to Intel's RAID technology, which allows the creation and management of RAID (Redundant Array of Independent Disks) arrays directly on the CPU rather than through a separate RAID controller card. VROC leverages the PCIe lanes available on Intel CPUs (particularly those with Intel Xeon and Intel Core processors that support VROC) to manage storage devices, providing better performance and flexibility for configuring RAID arrays, especially in systems with multiple NVMe drives.
