What RAID configurations are supported by Synology NAS?

Synology Network Attached Storage devices support a variety of RAID configurations, allowing users to tailor their data storage according to their performance and redundancy needs. The primary RAID levels supported include RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10. RAID 0 offers increased performance but does not provide redundancy, meaning if one drive fails, all data may be lost. RAID 1 duplicates the data across two drives, ensuring data redundancy at the cost of half the total usable capacity. RAID 5 strikes a balance by using a minimum of three drives and providing both performance and redundancy, utilizing parity information to recover data in case of a single drive failure. RAID 6 extends this by allowing for two drives to fail, which is ideal for critical data, requiring a minimum of four drives. RAID 10 combines the benefits of RAID 1 and RAID 0, providing both redundancy and improved performance, but it requires at least four drives. Additionally, Synology devices offer options like Synology Hybrid RAID, which allows a combination of different drive sizes and types. Users should consider their specific needs and the number of drives available when choosing a RAID configuration, as this decision will significantly impact data security and system performance.
