Redundant Array of Independent Disks
Redundant Array of Independent Disks (RAID) is a mechanism that can prevent data loss by combining multiple drives into one logical storage unit. Multiple drives provide redundancy by spreading data across them, which can provide protection against one or more drives failing based on the RAID level used. RAID configuration is easy as the default QNAP NAS settings will recommend an ideal RAID structure for your NAS.
QNAP NAS supports various RAID types that provide varying levels of performance and data redundancy. Based on the number of drives in your NAS, you can choose from single; RAID 0, 1, 5, 6, 10, 50, 60; and hot spare configurations.
QNAP NAS with the QuTS hero operating system also supports Triple Parity to provide protection against three drives failing, while the Triple Mirror provides mirroring protection for three drives.
RAID 50/60 strikes a balance between capacity, protection, and performance for high-capacity NAS with multiple drive configurations. For businesses using a NAS with over 10 drives, RAID 50/60 not only provides greater data protection than a single RAID 5/6, but also maximizes usable storage space compared to RAID 10. Besides data storage, and with the random write performance boost when using SSD RAID, RAID 50/60 also offers a great choice.
Automatic RAID disk replacement before potential failure
If potential drive errors are detected, QNAP NAS automatically moves data from the affected disk in a RAID group to a spare disk, before the data on the affected disk becomes inaccessible. This feature removes the need to wait for the system to replace drives only after a failure occurs and improves system reliability by preventing the need for lengthy (from hours to even weeks) RAID rebuilding which risks data loss and impacts system performance.
Expand a RAID group
You can increase the maximum storage capacity of a RAID group by replacing all member disks with higher-capacity disks. This operation can be performed while the RAID group is online and accessible to users.
Change the RAID type of a RAID group
When your data grows in importance, you can migrate the system from single-drive mode to RAID 1, RAID 5 or RAID 6 by adding additional hard drives. The migration process can be achieved without losing access to data or interrupting NAS services.
