RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical disk drive components into a single logical unit. RAID is used to improve data reliability and performance. There are different RAID levels, each with its own advantages and disadvantages.
Checking the RAID setting is important because it allows you to verify that your RAID is configured correctly and that your data is protected. You can check the RAID setting using a variety of methods, including the BIOS, the operating system, or a third-party software program.
