RAID: Redundant Array of Independent Disks
What is RAID and why is it used?
RAID, or Redundant Array of Independent Disks, is a method of storing the same data on multiple hard disks to protect data in case of a drive failure. Why do we use RAID in data storage systems?
Answer:
RAID is utilized in data storage systems to enhance data protection, improve performance, and achieve a balance between speed and fault tolerance.
RAID offers a way to safeguard data by distributing it across multiple disks, ensuring that if one disk fails, the data remains accessible on other disks. It also helps to enhance read/write speeds by spreading data across multiple disks. By using RAID, organizations can ensure that their critical data is secure and accessible even in the event of a hardware failure.
