What RAID configurations are supported by QNAP NAS?

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.
