RAID
RAID (Redundant Array of Independent Disks) configurations offer various ways to organize and protect data across multiple drives, providing improved performance, reliability, or a combination of both. RAID 0, known as striping, enhances performance by distributing data across multiple drives, but it offers no redundancy, meaning the failure of one drive results in the loss of all data. RAID 1, or mirroring, duplicates data across two drives, providing redundancy but not necessarily performance improvement. RAID 5 combines striping and parity to achieve both improved performance and data protection. If one drive fails, the parity information allows the system to reconstruct the data. RAID 6 is similar but provides additional redundancy by using dual parity, allowing the array to withstand the failure of two drives simultaneously. RAID 10, or RAID 1+0, combines mirroring and striping, offering both performance and redundancy by creating a striped set of mirrored drives. The choice of RAID configuration depends on specific needs, such as performance, data protection, or a balance of both, and is a crucial consideration in storage system
