Powered by an Intel® Celeron® J4125, quad-core 2.0 GHz processor, the TS-853DU-RP 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.
Build a Faster Network with QNAP
Powered by an Intel® Celeron® J4125 quad-core 2.0 GHz processor (burst up to 2.70 GHz), DDR4 dual-channel RAM (up to 8GB), two 2.5GbE Gigabit LAN ports, the TS-853DU-RP provides smoother multimedia playback and everyday NAS usage. Additional high-speed network options from QNAP include USB 3.2 Gen 1 to 2.5GbE/5GbE adapters (supports N-BASET/Multi-Gig), QXG 5GbE/10GbE PCIe cards, and QNAP QSW 10GbE switches. All these options allow users to revolutionize their network at a cost-effective price.
Extend NAS Functionality with a PCIe Card
With a PCIe Gen 2.0 x 2 slot, the TS-853DU-RP provides flexibility in extending NAS functionality and potential applications. To optimize system performance, install a QNAP QM2 card to add M.2 SATA or NVMe SSD caching/10GbE connectivity and use with Qtier tiered storage for optimal system performance. Wireless connectivity can be added by installing a QNAP QWA-AC2600. A QXG-10GbE/5GbE network card adds extra high-speed network ports. Alternatively, you can add an affordable QNAP QNA-UC5G1T USB 3.2 Gen 1 to 5GbE adapter to enjoy higher network speeds or boost the USB connectivity by installing a USB 3.2 Gen 2 (10Gbps) card.
Multi-Point File Backup, Access, and Sync
The TS-853DU-RP supports common file sharing protocols (including SMB/CIFS, AFP and NFS) for Windows®, Mac®, and Linux®/UNIX® devices. Coupled with Qsync (a utility that transforms a QNAP NAS into a secure, high-capacity data center for file synchronization) any file uploaded to the TS-853DU-RP becomes available for all linked devices, such as computers, laptops, and mobile devices. Hybrid Backup Sync helps you easily backup or synchronize data on the TS-853DU-RP to another QNAP NAS, remote server, or cloud storage for disaster recovery. Additionally, QuDedup technology greatly improves the efficiency and storage utilization of multi-version backup by deduplicating the backup data. You can install the QuDedup Extract Tool on your computer and restore deduplicated files to their normal status.
