QNAP HS-453DX 4GB Silent NAS

Do you need a secure, efficient way to store your data? Get the HS-453DX-4G desktop NAS from QNAP. Unlike normal external hard drives, you can simultaneously connect all computers in your network to this NAS (network-attached storage) device. It offers you ample storage space and requires significantly less electricity than regular PCs. It has an Intel Celeron J4105 1.5 GHz processor. It has Several users can access data at the same time thanks to the 4 GB of RAM. You can incorporate the following data storage forms in this desktop NAS system: 0, 1, 10, 5, 6 and JBOD. 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.

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. 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. You get a higher level of data security when implementing RAID 6, even if two hard drives fail, the system will still be operational.
