Supported RAID Configurations on QNAP NAS
QNAP NAS supports various RAID configurations, allowing users to optimize data protection and storage efficiency. The available RAID configurations are:
1. RAID 0 (Disk Striping)
Raid 0 combines multiple drives into a single logical unit, distributing data across all drives without redundancy. This configuration offers improved read/write speeds but offers no data protection. It is suitable for applications requiring high performance but not critical data security.
2. RAID 1 (Disk Mirroring)
Raid 1 duplicates data across multiple drives, offering data redundancy. It provides a high level of data protection, as if one drive fails, the data remains accessible from the mirrored drive. RAID 1 is suitable for applications requiring data integrity and availability.
3. RAID 5 (Disk Striping with Parity)
Raid 5 combines striping and parity, distributing data and parity information across multiple drives. If one drive fails, the system can rebuild the missing data using the parity information. It offers a good balance between storage efficiency and data protection.
4. RAID 6 (Disk Striping with Dual Parity)
Raid 6 provides enhanced data protection compared to RAID 5. It distributes data and dual parity information across multiple drives, allowing for the failure of two drives without losing data. RAID 6 is suitable for applications that require high data protection and availability.
5. RAID 10 (RAID 1+0)
Raid 10 combines mirroring and striping, offering both data redundancy and improved performance. It requires a minimum of four drives and provides good data protection with enhanced read/write speeds. RAID 10 is well-suited for applications with high I/O requirements.
6. RAID 50 (RAID 5+0)
Raid 50 combines striping and parity across multiple RAID 5 arrays. This configuration provides enhanced performance and fault tolerance compared to RAID 5. RAID 50 requires at least six drives and offers a good balance between performance and data protection.
7. RAID 60 (RAID 6+0)
Raid 60 combines striping and dual parity across multiple RAID 6 arrays. It offers improved performance and data protection compared to RAID 6. RAID 60 requires a minimum of eight drives and is suitable for applications with high data protection requirements and performance needs.
