Description
Qnap TS-853DU-RP-4G 8-Bay Rackmount NAS
Powered by an Intel® Celeron® J4125, quad-core 2.0 GHz processor, the Qnap TS-853DU-RP 8-Bay features two 2.5GbE RJ45 ports, providing up to 2.5 times the speed of Gigabit Ethernet and enabling smoother multimedia playback and everyday usage. With a PCIe Gen 2.0 x 2 slot, the TS-853DU-RP provides flexibility in extending NAS functionality, allowing you to install various cards for extra network ports, M.2 SSD caching/tiering, or Wi-Fi connectivity. The TS-853DU-RP ensures data security with AES 256-bit encryption, boosting system performance while ensuring the safety of sensitive business data stored.
2.5GbE connectivity accelerates file sharing between teams, and is idealfor office users for multimedia storage.
PCIe expansion allows for installing a 10/5/2.5GbE network card, USB 3.2 Gen 2 (10Gbps) card or QWA-AC2600 wireless adapter.
Snapshots fully record the system status and data. If files are accidentally deleted or modified, they can be quickly restored to previously-recorded states.
Scalable storage supporting virtualization, containerized apps, centralized storage, backup, sharing, and disaster recovery.
Qtier™ auto-tiering technology and SSD caching enable constant storage optimization.
Expand your storage capacity by using the unused storage of another QNAP NAS, or connect TR/TL series expansion enclosures.
