Answer / Rohil Kumar Sahaya
"RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical disks into a logical unit to improve performance or provide redundancy. There are several RAID configurations, such as: RAID 0 - Striping (no parity or mirroring), RAID 1 - Mirroring (duplicate data on two disks), RAID 5 - Distributed Parity (data striped and parity information distributed across all disks), RAID 6 - Double Distributed Parity (similar to RAID 5 with an additional parity disk for redundancy)."n
