RAID support is another important factor to consider when selecting a NAS system. Here is detailed information about RAID technology and its significance for NAS systems:

RAID Technology: RAID stands for Redundant Array of Independent Disks. It is a technology where data is distributed across multiple hard drives to achieve improved data security, performance, or both. RAID uses different RAID levels that employ various methods for data distribution and redundancy.
RAID Levels: There are different RAID levels that can be supported in NAS systems:
- RAID 0: RAID 0 provides performance improvement by distributing data across multiple drives. It increases read speed as data can be read simultaneously from different drives. However, RAID 0 does not offer redundancy, so a drive failure can result in data loss.
- RAID 1: RAID 1 mirrors the data onto two drives to provide redundancy and increased data safety. Each drive contains an identical copy of the data, so if one drive fails, the data remains accessible on the other drive.
- RAID 5: RAID 5 distributes data and parity information across multiple drives. The parity information allows for data recovery in case of a drive failure. RAID 5 provides both data security and performance benefits.
- RAID 6: RAID 6 is similar to RAID 5 but offers additional redundancy through dual parity information. This increases data safety as the system can still function even if two drives fail simultaneously.
There are also other RAID levels such as RAID 10, RAID 50, and RAID 60, which are combinations of different RAID levels and offer specific advantages and disadvantages.
Significance of RAID Support: RAID support is important for improving data security and availability on the NAS system. By using RAID, you can reduce the likelihood of data loss and ensure that your data remains accessible even in the event of a drive failure. RAID also provides better performance, especially in read and write operations, as data can be distributed across multiple drives.
