TS-251D Intel Dual-Core Multimedia NAS with a PCIe Slot for Extending NAS Functionality
The TS-251D integrates secure data storage and multimedia entertainment into one device. Featuring a PCIe slot, the TS-251D allows you to flexibly extend NAS functionality and potential applications. You can enhance overall system performance by installing a QNAP QM2 card for M.2 SSD caching/10GbE connectivity combined with Qtier auto-tiering storage and installing a 10GbE/5GbE/2.5GbE network expansion card. In addition, TS-251D can be used with QNAP’s smart AI photo management application, QuMagie, which integrates AI image recognition to group similar photos together in album “People”, “Things” and “Places”. The TS-251D features an HDMI™ slot to stream multimedia throughout your home. The TS-251D supports dual-channel hardware decoding and transcoding, allowing you to view NAS media files smoothly across various devices.
Flexible PCIe expansion
The PCIe port supports the installation of a 10GbE/5GbE/2.5GbE/ network expansion card, a QM2 card, a USB 3.2 Gen 2 (10Gbps) card, or a wireless network card.
4K HDMI™ output
Provide 4K media playback and online transcoding, while enabling cross-device multimedia viewing via HDMI™ output or streaming applications.
Snapshot protection against Ransomware
Snapshots fully record the system status and data. If files are accidentally deleted or modified, you can quickly restore previously-recorded data.
Centralized multimedia management
QNAP provides a wide range of multimedia applications. You can manage all apps through the Multimedia Console to simplify management.
Data backup and recovery
HBS backs up and synchronizes NAS data to other remote servers or cloud storage, while QuDedup deduplicates data at the source to reduce network bandwidth and storage space.
Flexible storage expansion
Use VJBOD (Virtual JBOD) to expand your storage capacity by using the unused storage of other QNAP NAS. Connect up to two TR series USB storage enclosure.
Available Models

Multi-Point File Backup, Access, and Sync
The TS-251D stores data and files centrally, and supports 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-251D 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-251D to another QNAP NAS, remote servers, or cloud storage for disaster recovery. Additionally, QuDedup technology greatly improves the efficiency of multi-version backup to the destination storage, while optimizing storage utilization. You can install the QuDedup Extract Tool on your computer and restore deduplicated files to their normal status.
Protect Important Data With Snapshots
Snapshots help protect your data by fully recording the NAS system state and metadata. You can use snapshots to quickly restore files to a previously-recorded state when files are accidentally deleted or modified, or when the system is compromised by ransomware. QNAP snapshots are block-based and only record modified data. Not only does this save storage space, but also reduces the time required to back up and restore data.

Extend NAS Functionality With The PCIe Slot
With a PCIe expansion Gen 2.0 x 4 slot, the TS-251D provides flexibility in extending NAS functionality and potential applications. To optimize system performance, install a QNAP QM2 card for M.2 SSD caching/10GbE connectivity and use with Qtier tiered storage for optimal system performance. You can also use the TS-251D as a wireless access point by installing a compatible QNAP QWA-AC2600 or QXP-W6-AX200 wireless network card to create a wireless media streaming environment. Moreover, by configuring the QXG-10GbE/5GbE network expansion cards, you can upgrade your network to high-speed connectivity with an existing CAT 5e cable. You can also boost the USB connectivity of the TS-251D by installing a USB 3.2 Gen 2 (10Gbps) card.
