QNAP TS-251+ 2GB 2-bay NAS

If you're in need of a secure and efficient way to store your data, then QNAP's TS-251+-2G desktop NAS is a great choice. Different from normal external hard drives, the NAS (network-attached storage) device can be integrated directly into your network. This gives all computers connected to your network access to the device and data. It offers you sufficient storage space and uses much less power than regular PCs. It has an Intel Celeron quad-core 2.0 GHz processor. It has With this model's 2 GB of RAM several users can access its data at the same time. The following data storage arrays are available for this desktop NAS system: JBOD, 1 and 0. Using a JBOD architecture to create a multi-disk storage space means you can combine hard drives of random sizes and will not lose the storage capacity of any of them. This is not the case with RAID levels.

RAID 0 stores your data on multiple drives, which increases performance and speed as all work is split among the various drives rather than handled by just one. The drives should ideally have equal storage capacities and a minimum of two drives are required. This RAID level offers no fault tolerance and is therefore best suited for large volumes of high speed storage. 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.
