Why Use a RAID Controller?

RAID cards improve overall system performance by distributing data across multiple drives. This allows parallel I/O operations, improves read/write speeds, and provides redundancy to protect against drive failures.

🔧 Common Standard RAID Levels
RAID 0 – Striping Only
Distributes data across multiple disks for faster access. No redundancy. One disk fails = all data lost.

RAID 1 – Mirroring Only
Duplicates data to another disk. High redundancy, low storage efficiency. Ideal for critical backups.

RAID 2 – Bit-Level Striping + Error Correction
Uses bit-level data striping with error correction (FEC). Rarely used today.

RAID 3 – Byte-Level Striping + Dedicated Parity
Uses one disk for parity and distributes data by bytes. Suitable for large sequential data but limited multi-user access.

RAID 4 – Block-Level Striping + Dedicated Parity
Similar to RAID 3, but stripes data by blocks instead of bytes. Rarely implemented due to performance bottlenecks.

RAID 5 – Block-Level Striping + Distributed Parity
Widely used for file and application servers. Can survive the failure of one drive. Efficient and balanced.

RAID 6 – Dual Parity for High Redundancy
Similar to RAID 5, but stores dual parity across drives. Can withstand failure of two drives. Ideal for enterprise setups.

Why RAID is Perfect for You

If you work with large files (video editing, music production, design projects, etc.), RAID provides the speed, redundancy, and performance you need for a smooth workflow and secure storage.
