RAID

What is RAID 10 (RAID 1+0)? RAID 10, also known as RAID 1+0, is a powerful combination of RAID 1 (mirroring) and RAID 0 (striping). It offers the best of both worlds—high performance and fault tolerance. In RAID 10, data is first mirrored for redundancy and then striped across multiple drives to boost speed. This

Invention Date & History What is RAID 6? RAID 6 (Redundant Array of Independent Disks, level 6) is a storage configuration that offers fault tolerance through double parity. It allows up to two simultaneous disk failures without losing data. RAID 6 stripes data and two sets of parity information across all disks. It uses block-level

Invention & History How RAID 5 Works RAID 5 combines data striping (like RAID 0) with distributed parity for redundancy. 🔁 Example Layout (with 3 disks): Stripe Disk 1 Disk 2 Disk 3 1 Data A1 Data A2 Parity A 2 Data B1 Parity B Data B2 3 Parity C Data C1 Data C2 RAID

Invention & History How RAID 1 Works Example: If you store a 100 MB file: In this image we can see that there are 2 Disks and data is copied (mirrored) evenly across both the disks. Data A1 from Disk 1 is copied to Disk 2 Data A3 from Disk 1 is copied to Disk

Invention & History How RAID 0 Works Example: Let’s say you want to write the word LINUX across 2 disks: Both disks operate simultaneously, increasing throughput. In this image we can see that there are 2 Disks and data is split (striped) evenly across both the disks. Features Feature Value Minimum Disks 2 Redundancy ❌

RAID (Redundant Array of Independent Disks) is a data storage virtualization technology that combines multiple physical disk drives into one logical unit for improved performance, reliability, or both. It is commonly used in servers, NAS systems, and data centers. Why Use RAID? How RAID Works RAID works by distributing data across multiple drives using methods
