: A more space-efficient form of redundancy that calculates a checksum for data blocks. If a drive fails, the missing data can be reconstructed using the parity information stored on the remaining disks. Common RAID Levels
: This technique splits data across multiple drives. By allowing parallel access to different segments of data simultaneously, striping significantly boosts read and write performance. Raid.rar
Different "levels" of RAID offer various trade-offs between speed, capacity, and safety: : A more space-efficient form of redundancy that
: This involves duplicating data across two or more disks. It provides high fault tolerance; if one drive fails, the system can seamlessly continue operating using the mirror. By allowing parallel access to different segments of
The technology operates through several architectural techniques that define how data is distributed across the physical disks:
(Redundant Array of Independent Disks) is a fundamental storage technology used to improve data reliability, performance, or both by combining multiple physical disk drives into a single logical unit. Originally conceptualized in the late 1980s as "Redundant Arrays of Inexpensive Disks," it has evolved into a critical component for modern servers and high-performance workstations.
