RAID Levels Overview
RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical disk drives into a single logical unit for data redundancy, performance improvement, or both.
- Data Redundancy
- Improved Performance
- Increased Storage Capacity
- Fault Tolerance
RAID 0 (Striping)
RAID 0 splits data across multiple drives to improve performance. It provides no redundancy but offers the best performance and full storage capacity.
- Minimum 2 drives required
- No redundancy
- Best performance
- Full storage capacity
RAID 1 (Mirroring)
RAID 1 creates an exact copy of data on two or more drives. It provides redundancy but uses half of the total storage capacity.
- Minimum 2 drives required
- Full redundancy
- Good read performance
- 50% storage efficiency
RAID 5 (Distributed Parity)
RAID 5 distributes parity information across all drives. It provides redundancy while maintaining good performance and storage efficiency.
- Minimum 3 drives required
- Single drive redundancy
- Good read performance
- High storage efficiency
RAID 6 (Double Parity)
RAID 6 uses two sets of parity data for enhanced redundancy. It can survive the failure of two drives while maintaining good performance.
- Minimum 4 drives required
- Double drive redundancy
- Good read performance
- High storage efficiency
RAID 10 (Striped Mirrors)
RAID 10 combines the benefits of RAID 0 and RAID 1. It provides both performance and redundancy through striping and mirroring.
- Minimum 4 drives required
- Mirroring with striping
- Excellent performance
- 50% storage efficiency
