Marketing Information

The compact and feature-rich TS-451DeU combines an Intel® Celeron® dual-cord 2.0 GHz processor and 2.5GbE connectivity in one chassis, providing businesses with a modern 2.5GbE NAS solution to tackle everyday tasks like file backup/restore, and to boost team collaboration with higher productivity. The space-efficient short depth design makes it easy to install in small media cabinets or places with a lot of cabling. Supporting abundant business and media applications (including file sharing and sync, snapshot protection, virtual machines, cloud storage gateways, video streaming and real-time transcoding) alongside expandable storage capacity and install-on-demand apps, the TS-451DeU is an ideal cost-effective entry-level rackmount NAS.

  • Up to 5 Gbps transfer speeds can be made by setting port trunking with the two built-in 2.5GbE ports.

  • Dual M.2 2280 SATA 6Gb/s SSD slots allows tool-less SSD installation, and supports SSD caching to increase IOPS performance.

  • HBS provides comprehensive backup and data recovery; QuDedup deduplicates the data at the source to reduce storage space usage, bandwidth usage, and backup time.

  • Supports Plex® media server with hardware transcoding for an optimal multimedia experience.

  • Hosts multiple virtual machines and containers to run a wide range of applications on one NAS device.

  • Scale your storage capacity to fit growing data needs by connecting QNAP's expansion units.

Smaller footprint for bigger opportunities

Compared to a traditional 4-bay rackmount NAS, the compact TS-451DeU has a depth of only 11.57 inches (295 mm). This makes the TS-451DeU an excellent choice for smaller racks, and the unused space can be reserved for cabling or ventilation. The TS-451DeU is space-saving for flexible deployment and is especially suitable for multiple locations and applications including offices, audiovisual rooms, and security surveillance recording.

Dual-core 2.0 GHz (bursts up to 2.9 GHz) with AES-NI encryption acceleration

The TS-451DeU supports SATA 6 Gb/s drives and features a power-efficient Intel® Celeron® J4025 dual-core 2.0 GHz processor (bursts up to 2.9 GHz). There are two DDR4 SODIMM memory slots with 2 GB DDR4 memory as standard, but can be upgraded up to 8 GB. With Intel® AES-NI encryption engine, the TS-451DeU provides unmatched encryption performance with AES-256 bit encryption acceleration, boosting system performance while ensuring the safety of sensitive business data stored in the NAS.

Follow the Wi-Fi 6 trends and upgrade to a 2.5GbE NAS

The new-gen Wi-Fi 6 (802.11ax) trend has driven higher bandwidth demands for wired and wireless network connections. The TS-451DeU comes with two 2.5GbE RJ45 LAN ports that allow you to use existing CAT5e cables to upgrade network speeds from 1 Gigabit to 2.5 Gigabit. The dual 2.5GbE ports also support Port Trunking for up to 5 Gbps transmission speeds!

Future-proof your IT infrastructure for high-speed networks

QNAP provides comprehensive, budget-friendly storage and networking solutions, allowing you to easily and flexibly upgrade network environments for bandwidth-hungry applications.

SSD caching and auto-tiering optimize application performance

Besides using 2.5-inch SSDs for cache acceleration, the TS-451DeU features two M.2 SSD slots that enable you to install SATA 6Gb/s M.2 SSDs with 2280 form factors (sold separately). Coupled with QNAP's SSD-aware features, the TS-451DeU maximizes performance with high cost-effectiveness.
