QNAP TS-863XU-4G 8-bay NAS

QNAP's TS-863XU-4G rackmount NAS is a secure, efficient storage solution for your data. This TS-863XU-4G NAS (network-attached storage) device, unlike the usual external hard drives, can be integrated directly to your network. It also uses much less electricity than regular PCs and offers you ample space for all your data. It has an AMD quad-core 2.0 GHz processor. It has The 4 GB RAM allows several users to access 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, JBOD, 6 + hot spare, 5 + hot spare and 10 + hot spare. 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. RAID 1 offers you high data security through data mirroring. A replica is created of all your data from one drive to another, meaning if one crashes you will still retain all of your information. This also means that the capacity of all your drives is halved because of duplicated content. For smaller NAS systems RAID 1 is an ideal option. When using RAID 5 your data is split among multiple drives and when one drive has an error the data is then copied and distributed to the other drives. This method offers you high data security and you can retain the total storage capacity of all your drives. It's the optimal choice for larger NAS systems with more than three hard drives. When using RAID 6 you get higher data security, even if two hard drives fail, the system will still function.
