It has The 1 GB RAM allows several users to access data at the same time. You can incorporate the following data storage forms in this desktop NAS system: JBOD, 1 and 0. When using JBOD (or "just a bunch of disks") you can combine several hard drives, regardless of their storage capacity, and retain all of the storage space. This is not the case with RAID levels.

When using RAID 0, hard drives (ideally of equal storage capacities) are interconnected and work in parallel — this means a higher, faster performance as computer tasks are not handled by just one drive. However, there is no fault tolerance because data is not mirrored, which means this RAID level is better suited for high speed storage of large volumes of data. Using RAID 1 means you get high data security. This is achieved by mirroring, which simply means that your data is duplicated from one drive to another, so that if one fails, nothing is lost. This also means that the total storage capacity of your drives will be halved. RAID 1 is best suited for smaller NAS systems.
