RAID stands for Redundant Array of Independent Disks. RAID allows multiple hard disks to work together in several ways. The Thecus N5200 supports RAID 0, 1, 5, 6, 10 and JBOD modes natively. The system also supports RAID Migration and RAID Expansion features for multiple setups. RAID is used to achieve greater storage space spanning across multiple drives, mirror the data across multiple drives and have higher reliability than older drives depending on the RAID Mode in use.

RAID 0 is called striping two or more drives are used to make a single drive. It improves performance but is poor for redundancy. Data is shared across different drives. If a single drive on the array is compromised, the whole array can go down. RAID 1 mirrored is a backup solution, allowing the end user to use the array if a single drive fails. RAID 5 (shared disks with parity) combines three or more disks sin an array where if one of the drives fails the storage capacity of the array is reduced by one disk. RAID 6 allows the recovery from the loss of two disks. RAID 10 means that there are two sets of mirrored RAID 0 disks on the five drives of the NAS.

SCSI drives have mostly been taken out of the equation being replaced by high-speed SATA drives, as the SATA drive offers nearly the same throughput as the SCSI interface for a lower price. The N5200 has five drive bays each capable of containing a 3.5 HDD with 1TB of storage space or more. Thecus offers drives for sale with the N5200 as an option, but you can purchase your own drives to save money. The drive bays use the SATA II interface meaning that they have the ability to be hot-swapped. Hot swapping involves removing a drive even when the system is running. This is useful if a drive fails and you need to replace the drive in a RAID array right away. Thecus has a Hard Drive compatibility list on their website and one notable problem is early Velociraptor HDDs from WD as the SATA interface is not correctly aligned to install in this unit. Newer Velociraptor HDDs fit without issue.
