RAID Levels

RAID (Redundant Array of Independent Disks) is a system that combines multiple hard drives to improve performance or protect data. Different RAID levels spread data across disks in various ways: some duplicate data on multiple drives (like RAID 1, for safety), others split data to boost speed (like RAID 0). Some levels mix both methods for a balance of safety and performance. Essentially, RAID helps ensure your data is more reliable and can be accessed faster, depending on the chosen configuration.
