RAID - mysterious storage magic!
RAID - what it is really? RAID (Redundant Array of Independent Disks) combines multiple drives into one logical volume to improve performance, capacity, or redundancy ; choose the RAID level based on whether you prioritize speed (RAID 0), protection (RAID 1/6/10), or a balance (RAID 5/50/60) . What is RAID RAID groups two or more physical disks into a single logical unit so the system can stripe (split) data, mirror (duplicate) data, or store parity (recovery information) across drives. This lets systems present one large volume while gaining speed, fault tolerance, or both. Why RAID is useful RAID improves uptime, throughput, and usable capacity compared with single drives. It can prevent data loss from a single drive failure (depending on level), increase read/write performance for demanding workloads, and simplify storage management by exposing one logical disk to the OS. Common RAID types and how they work: RAID 0 (striping): Splits data across drives for maximum speed...
