QNAP TS-1253BU-4G 12-bay NAS

Get your team a secure, efficient way to store data with QNAP's TS-1253BU-4G rackmount NAS. Le système NAS TS-1253BU-4G est directement raccordé au réseau - au contraire des disques durs externes normaux. Vous travaillez ainsi de manière efficace en matière d’énergie et économisez du courant en comparaison d'un ordinateur conventionnel. Tous les ordinateurs reliés au réseau peuvent profiter de la mémoire de the rackmount NAS. It has It has an Intel Celeron J3455 1.5 GHz processor. The 4 GB RAM allows several users to access data at the same time. The following data storage forms are available for this rackmount NAS system: 0, 10, 6, 5, 1, 10 + hot spare, 6 + hot spare, 5 + hot spare 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. 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. 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.
