What is raid definitions?

1. RAID - RAID stands for Redundant Array of Independent Disks. It is a data storage technology that combines multiple physical hard drives into a single logical unit. RAID is used to improve the overall performance, reliability, and availability of the data stored on the drives.

2. RAID Level - RAID Level is a way of categorizing different RAID configurations based on their performance, reliability, and availability attributes. Different RAID levels are suitable for different applications and data storage needs.

3. Striping - Striping is a technique used in RAID configurations that breaks up data into blocks and spreads those blocks across multiple drives. This technique helps to improve the performance of the RAID by allowing it to read and write data from multiple drives simultaneously.

4. Mirroring - Mirroring is a technique used in RAID configurations that duplicates data across multiple drives. This technique helps to improve the reliability of the RAID by providing redundancy in case of drive failure.

5. Parity - Parity is a technique used in RAID 5 and RAID 6 configurations to provide redundancy. In Parity, instead of duplicating data across multiple drives, a portion of each drive is reserved for parity information. This information allows the RAID to rebuild data in case of drive failure.
