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. 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. 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. SSD Caching and Auto Tiering for Optimized Storage Efficiency The TS-853DU-RP supports SSD caching to improve the workflow of random IOPS demanding applications such as virtualization. Qtier™ Technology empowers the TS-853DU-RP with auto tiering that continuously optimizes storage utilization across high-performance SSD and high-capacity SATA drives. Qtier™ 2.0 features IO-awareness that empowers SSD tiered storage with a cache-like reserved space to handle burst I/O in real time, greatly maximizing the advantages of SSD.
