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.

Intel® Celeron® J4025 Dual-Core Processor and AES-NI Hardware Encryption
Powered by Intel® Celeron® J4025 dual-core 2.0 GHz processor (burst up to 2.9 GHz), DDR4 RAM (up to 8 GB), one Gigabit LAN port, and supports SATA 6Gb/s hard drives, the TS-251D combines network expansion cards to create dependable read/write performance. The TS-251D features Intel® AES-NI 256 hardware-accelerated encryption for both full NAS volumes and shared folders, boosting system performance while securing sensitive data stored in the TS-251D.

Smart AI Photo Management
QuMagie integrates QuMagie Core AI image recognition technology for facial recognition, subject identification, and geotagging photos. Similar photos are categorized into People, Places, and Things albums. Moreover, QuMagie features a built-in timeline scroll, customizable folder covers, iOS® Live Photo display and a powerful search tool, to provide you with the ultimate photo management and image sharing solution.

Real-Time 4K Video Transcoding
Featuring advanced Intel® UHD Graphics, the TS-251D supports dual-channel 4K hardware decoding and real-time transcoding, allowing you to convert videos to universal file formats that can be smoothly played across various devices*. You can also watch high-quality 4K media files on an HDTV using the HDMI output or with Plex® Media Server to stream media files to mobile devices and media streaming devices (including DLNA®, Roku®, Apple TV® (via Qmedia), Amazon Fire TV® and Chromecast™). The QNAP RM-IR004 remote control (sold separately) can be configured using QButton to customize individual button actions, providing a more user-friendly NAS experience.

Multiple Ways To Enjoy Your Multimedia
QNAP provides a wide range of multimedia applications for you to easily enjoy photos, music, and videos.

Multimedia Console consolidates all QTS multimedia applications into one app for easier and centralized multimedia app management.

Cinema28 enables single-interface management of all media files and can stream files to every connected device throughout your home.

Qmedia allows music, photos and videos to be effortlessly streamed to Android TV™, Apple TV® (via Qmedia), and Amazon Fire TV or set-top boxes.

Easy and Secure File Management
File Station centralizes files stored on your TS-251D and in the cloud. You can easily upload files from your computer, drag and drop files between folders, rename files, delete files, and configure file and folder permissions to prevent unauthorized access. Moreover, with Microsoft Office Online you can open and modify Microsoft Office documents stored on the TS-251D, without having to download Word documents, Excel worksheets, and PowerPoint presentations from your NAS to the PC. When it comes to sharing sensitive or confidential files on the TS-251D, you can use File Station to enhance data security effectively by encrypting files into a .qenc file, set a password, and then have file recipients use QENC Decrypter to decrypt the sent file.

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 QXP-W6-AX200 or QWA-AC2600 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.

QVR Pro Safeguards Your Environment
QNAP’s QVR Pro surveillance solution allows you to arrange dedicated, independent storage space for surveillance data on the TS-251D and leverages scalable storage advantages. With QVR Pro, camera management, storage space allocation, camera live view, and playback is greatly simplified. You can also use USB webcams as network cameras with the QUSBCam2 app, and remotely monitor surveillance feeds anytime with QVR Pro Client mobile app.

Multiply Your Productivity
The app-driven QTS operating system provides solutions for simplifying file backup, management, search, and more.

QmailAgent
Centrally manage and switch between different email accounts, back up emails to the NAS, and safeguard email security and personal privacy.

Notes Station 3
Notes Station 3 can bring the advantages of collaborative note-taking with improved productivity to provide higher efficiency for your workgroup.

Smart Filing
Qfiling automates file organization. Files are automatically archived into folders based on your settings.

Flexible and Economical Storage Expansion
QNAP provides an easy and flexible solution for increasing storage capacity before you run out of storage space. Here are the following ways you can expand NAS storage for accommodating data and business growth:

Upgrade RAID Capacity
Hot-swap lower-capacity drives with larger-capacity drives for your QNAP NAS to grow with your business.

VJBOD
Use Virtual JBOD (VJBOD) to expand storage capacity by using unused storage in other QNAP NAS. Up to 8 QNAP NAS can be mounted as local disks on the TS-251D.

Attach Expansion Enclosures
Easily expand NAS capacity by connecting two TR-002, TR-004 USB hardware RAID external enclosures with QNAP’s Storage & Snapshots Manager application.
