QNAP TS-855eU: High-speed 8-bay NAS with dual 2.5Gbe ports

The QNAP TS-855eU-8G-US is a high-performance, 2U rackmount Network Attached Storage (NAS) device designed for businesses and professionals requiring robust data management, virtualization, and high-speed file sharing. It features an Intel Atom C5125 processor with 8 cores and a clock speed of 2.8 GHz, providing efficient computing power for virtualization tasks and multitasking. The system comes with 8GB of DDR4 SODIMM memory, which can be upgraded to a maximum of 64GB with ECC support, ensuring stability and performance for demanding applications. This NAS is diskless, meaning it does not include hard drives, allowing users to install their own storage solutions based on their specific needs. It is ideal for environments that require scalable storage and high-speed data access across multiple devices and teams.


The TS-855eU-8G-US includes dual 2.5GbE network ports that support speeds of up to 2.5 Gbps, 1 Gbps, or 100 Mbps, enabling fast file transfers and seamless connectivity across local networks. These ports are particularly useful for large file transfers or when multiple users need to access shared files simultaneously. Additionally, the device has two M.2 PCIe Gen 3 x4 NVMe SSD slots that can be used for cache acceleration or as part of an SSD storage pool to enhance overall performance. These slots allow for faster read/write speeds and improved responsiveness when handling large datasets or virtual machines.


The NAS also features two PCIe Gen 3 x4 expansion slots, which provide flexibility for adding additional network adapters, QM2 cards, or Fibre Channel cards to further enhance performance and connectivity options. This makes the TS-855eU-8G-US suitable for advanced networking configurations or specialized applications that require high-speed data transfer capabilities. The device supports comprehensive backup solutions for Google Workspace and Microsoft 365 accounts and files through Boxafe, ensuring that critical business data is securely stored and easily recoverable in case of data loss or corruption.


QNAP’s QVR Pro surveillance solution allows users to create a 24/7 security system by integrating with IP cameras and other surveillance devices, making this NAS a versatile option for businesses that require both data storage and security monitoring capabilities. Additionally, the TS-855eU-8G-US supports disaster recovery planning with ransomware protection through QNAP’s storage snapshot solution, which enables users to create point-in-time copies of their data for quick recovery in the event of an attack or system failure. This feature is particularly valuable in protecting sensitive business data from potential threats while maintaining system performance through AES-256 bit encryption acceleration provided by the Intel® AES-NI encryption engine.
