With a PCIe expansion slot, the TS-251B provides flexibility in extending NAS functionality and potential applications. Install a QNAP QM2 card to provide M.2 SSD caching/10GbE connectivity and use with Qtier tiered storage for optimal system performance; use the TS-251B as a wireless access point by installing a compatible wireless network card (such as the QNAP QWA-AC2600) to create a wireless media streaming environment; or boost the USB connectivity of the TS-251B by installing a USB 3.1 Gen 2 (10Gbps) card.

A tailor-made private wireless network that meets your needs
By installing the QWA-AC2600 and WirelessAP Station app, your NAS will evolve into a high-performance wireless access point that can be connected to from multiple devices. The QWA-AC2600 can also be used to extend your wireless network coverage. Combined with useful features (including DHCP and NAT) provided by the Network and Virtual Switch app, the QWA-AC2600 can be used for a variety of applications, delivering private, fast, low-latency and secure connectivity across your home and/or workplace. (WirelessAP Station requires Container Station to be installed on your QNAP NAS.)

Upgrade your network to 10GbE with QNAP's fast and affordable 10GbE Switch
QNAP 10GbE/NBASE-T™ unmanaged switches allow you to instantly upgrade your network environment at a cost-effective price. With a 10GbE network you can enjoy blazing-fast transfer speeds, empower bandwidth-demanding tasks like virtualization, and enable simultaneous real-time access to large NAS-based files using multiple workstations (ideal for video editing and multimedia). QNAP also provides a 10GbE PCIe network expansion card for the TS-251B and Windows®/Linux® PCs to take advantage of high-speed LAN environments.

Real-time 4K video transcoding
Featuring advanced Intel® HD Graphics, the TS-251B supports dual-channel 4K H.264 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@30FPS media files on a HDTV using the HDMI output or use with Plex® Media Server to stream media files to mobiles devices and media streaming devices (including DLNA®, Roku®, Apple TV®, Amazon Fire TV® and Chromecast™). The QNAP RM-IR004 remote control (sold separately) can be configured using QButton to customize the actions of individual buttons, providing a more convenient 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.

- Cinema28 allows for single-interface management of all your media files and can stream files to every connected device throughout your home.
- QVHelper allows users to stream media files or music playlists from a QNAP NAS to VLC player.
- Qmedia allows music, photos and videos to be effortlessly streamed to Android TVs or set-top boxes.
- Video HD is a free KODI add-on that combines KODI's streaming and video decoding capabilities and fully supports Video Station's features.

Protect important data with snapshots
Snapshots help protect your data by fully recording the NAS system state and metadata. If files are accidentally deleted or modified or the system is afflicted by ransomware, you can use snapshots to quickly restore files to a previously-recorded state. QNAP snapshots are block-based and only record the changed data. Not only does this save storage space but also reduces the time required to back up and restore data. The TS-251B supports up to 1,024 snapshots per NAS and up to 256 snapshots per volume or LUN.

Consolidated notifications and extra NAS security
QTS 4.3.5 provides various mechanisms to ensure the data saved on your TS-251B is carefully safeguarded, including the brand-new Notification Center that consolidates system logs and notifications into a single app and the Security Counselor that checks for weaknesses and offers helpful security recommendations.

Notification Center
Consolidates system logs and notifications for all NAS apps into a single app with flexible rule settings, facilitating smooth and easy NAS management.

Security Counselor
Checks for weaknesses and offers recommendations to enhance NAS security. Anti-virus and anti-malware software is also integrated within Security Counselor to ensure the complete protection of your NAS and data.

Automate everyday tasks with IFTTT Agent
QNAP IFTTT Agent integrates the popular web automation service IFTTT (If This Then That), allowing you to create a near-unlimited number of automated workflows. Simply connect your IFTTT account with your TS-251B and set triggers and actions. For example, if you set a trigger as “Any new photo on the phone” and the action as "Upload the photo to QNAP NAS," then all the photos taken using your phone will be automatically uploaded to TS-251B.

Multiply your productivity
The app-driven QTS operating system provides solutions for simplifying file backup, management, search, and more. With File Station you can view and manage your files from NAS and multiple storage devices; the OCR Converter allows you to extract text from images; Qfiling helps automate file organization, and Qsirch helps quickly find files.

Centralized File Management
Use File Station to directly access files on USB devices - including optical disc drives. Files from different devices can be easily viewed and managed on a single interface.

File Digitization
OCR Converter extracts text from images, helping to boost productivity and making it easier to find files.

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

Full-text Search
Qsirch quickly finds images, music, videos, documents, emails, and other files.

Multi-point file backup, access and sync
The TS-251B centrally stores data and files, and supports SMB/CIFS, AFP and NFS protocols for file sharing across Windows®, Mac®, and Linux®/UNIX® devices. Coupled with Qsync (a utility that turns a QNAP NAS into a safe, high-capacity data center for file synchronization) any file uploaded to the TS-251B will be made available for all linked devices, such as computers, laptops and mobile devices. Hybrid Backup Sync can help you easily backup or synchronize data on the TS-251B to other QNAP NAS, remote servers, or cloud storage for easy disaster recovery.

QVR Pro safeguards your environment
