WD My Cloud EX2 Ultra 8TB 2-bay NAS

With the WDBVBZ0080JCH-EESN desktop NAS from Western Digital you can safely store your files and data. Because of its substantial capacity of 8 TB you'll have enough space for everything you need. Unlike traditional 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 ample storage space and uses much less electricity than regular PCs. It has a Marvell ARMADA 2-core 1.33 GHz processor. It has a Gigabit Ethernet port. The 1 GB RAM allows several users to access data at the same time. This desktop NAS system has the following data storage forms available: JBOD, 1 and 0. 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.

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. 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.
