RAID 5 is designed to provide both redundancy and improved read performance while requiring a minimum of three disks. This RAID level utilizes striping with parity, meaning data is divided into blocks that are distributed across the drives, and additional parity information is stored on one of the drives. In the event of a single disk failure, the data can still be reconstructed using the parity information, ensuring data availability and redundancy.

One of the key advantages of RAID 5 is that it effectively balances capacity and redundancy. While it offers fault tolerance, it also retains a significant amount of usable storage space compared to other RAID levels that may offer redundancy. This makes it particularly suitable for environments where read operations are frequent, as the simultaneous access to multiple disks enhances read performance.

Overall, RAID 5 is ideal for situations that require both reliable data protection and efficient read capabilities, making it a popular choice in server setups that prioritize performance alongside data integrity.
