RAID (Redundant Array of Independent Disks) is a way of combining multiple physical or virtual disks to improve reliability, performance, or both. In a lab environment, we simulate RAID inside a VM so you can see how Windows detects and manages mirrored or striped volumes. In this activity, you will add extra virtual disks, configure RAID levels such as RAID 1 (mirroring) in Disk Management, and observe how the system behaves when a disk fails.

You can watch my YouTube video that demonstrates this RAID configuration lab using VirtualBox.
