{"raid": "RAID (Redundant Array of Inexpensive Disks) is a method for storing data across multiple disks to improve performance, reliability, and fault tolerance.
"raid levels": "There are five common RAID levels: RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10 (also known as RAID 1+0). RAID 0 provides no redundancy but improves read performance by striping data across multiple disks. RAID 1 mirrors data on two identical disks for improved reliability. RAID 5 distributes parity information across all disks to provide fault tolerance and better read performance. RAID 6 is similar to RAID 5 but includes an additional parity disk for increased fault tolerance. RAID 10 combines mirroring and striping for improved performance and redundancy."}
