QNAP TS-863XU-RP 4GB 8-bay NAS

The TS-863XU-RP-4G rackmount NAS from QNAP safely stores your data and files. This TS-863XU-RP-4G NAS (network-attached storage) device, unlike traditional external hard drives, can be directly integrated to your network. It also needs far less electricity than regular PCs and offers you over enough space for all your data. The rackmount NAS device and is equipped with an AMD quad-core 2.0 GHz processor. With this model's 4 GB of RAM several users can access its data at the same time. You can incorporate the following data storage forms in this rackmount NAS system: 0, 10, 6, 5, 1, 50, 60 and JBOD. JBOD (or "just a bunch of disks") allows you to connect hard drives of various sizes to create a multi-drive storage system. Unlike RAID levels, you will not lose any storage capacity of the various drives you combine.

Using RAID 0 means your hard drives (ideally of equal storage capacities) are interconnected and work parallely. This increases performance and speed as the work is split bewteen multiple drives, but there is no fault tolerance. 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. RAID 5 stores your data on multiple drives, which gives you high data security. If a drive begins to fail, the data it holds will be recreated and distributed to the other drives allowing users to continue working uninterrupted. For larger NAS systems with more than three hard drives RAID 5 is the ideal choice to retain optimal data security and total drive storage capacity. RAID 6 offers you high data security and is still operational even if two hard drives in the system fail.
