Redundant Array of Independent Disks (RAID) is a data storage technology that combines multiple hard drives into a single unit to improve data redundancy, performance, or both. By storing copies of data across different drives, RAID configurations can protect data against loss in case of a drive failure, enhancing system reliability. Different RAID levels (e.g., RAID 0, RAID 1, RAID 5, RAID 6, RAID 10) offer various balances of performance, redundancy, and storage efficiency, catering to different organizational needs. VDURA systems support a range of RAID levels, allowing flexibility to optimize for speed, data protection, or capacity based on specific application requirements. By using RAID, VDURA enhances data resilience and supports high-performance environments where continuous data availability is essential.
