High performance
Powered by a new 22nm 64-bit dual-core Intel® Celeron® 2.41GHz processor with 1GB energy-efficient DDR3L RAM upgradable up to 8GB, coupled with the support of dual LAN ports and HDMI connectivity, the TS-251 is a powerful home NAS with supreme value and great performance to deliver up to 220MB/s read & write speeds. The TS-251 can also automatically increase the processor's clock rate from 2.41GHz to 2.58GHz when needed for CPU-intensive tasks. The TS-251’s fast encryption and decryption performance provides transfer speeds of up to 68MB/s with AES-256 bit volume encryption, boosting system performance & security while ensuring the safety of sensitive personal data stored in the TS-251.

QTS - Simple and efficient
Thanks to the intuitive user interface of QTS, system operations of the TS-251 are smooth and handy. Its intelligent desktop allows you to find desired functions quickly, create desktop shortcuts or group shortcuts, monitor important system information on a real-time basis, and open multiple application windows to run multiple tasks concurrently, bringing greater operating efficiency.

Easily build your personal cloud and access anywhere
QNAP’s myQNAPcloud provides an always-connected infrastructure for business and home users to build their private or personal cloud with ease. Through any web browser or the free mobile app the TS-251 becomes your personal cloud so you are always connected to your data. Take advantage of the myQNAPcloud service, which allows you to remotely access your TS-251 wherever you are. Instantly stream or share your multimedia contents and share them with your friends.

Real-time & offline HD video transcoding
The TS-251 delivers superior real-time Full HD video transcoding to convert your videos to formats that can be smoothly played on PCs, mobile devices and Smart TVs. It allows for up to 5 devices to simultaneously view different videos stored on the TS-251 with on-the-fly hardware accelerated transcoding. The TS-251 allows you to enjoy instant videos on multiple devices - even those that lack computing power or have limited file format support - without the need for complicated and time-consuming file conversion.

With the benefit of offline transcoding, if you can only connect to an Internet connection with limited/restricted bandwidth, you can still enjoy smooth videos by selecting a pre-rendered lower resolution to play the videos via File Station, Video Station, or the Qfile app for iOS & Android without affecting the TS-251’s performance running other applications. This also allows more people to play videos via streaming. The TS-251 also allows you to set a dedicated folder for automatic video transcoding.

Stream media via DLNA, AirPlay, and Plex
You can use DLNA-compatible devices such as HDTVs, Smart TVs, Sony® PS3, Microsoft® Xbox 360 and Hi-Fi systems to enjoy HD quality videos and high-resolution audio content such as DSD Direct Stream Digital audio format stored on the TS-251. You can also use the Qfile app on an iOS device to browse videos and photos stored on the TS-251 and play on the TV via Apple TV. By installing the QAirplay app, available on the QTS App Center, you can stream your media content directly on a TV via Apple TV. The media contents are streaming on Apple TV, bypassing your mobile device, thus saving the energy of your mobile device. The TS-251's support for Plex Media Server organizes all of your media with rich information and transforms the TS-251 into a powerful & easy to use streaming machine with DLNA, Roku, Amazon Fire TV, and Google TV support.

Enjoy Full HD videos with HD Station via HDMI
QNAP HD Station integrates the powerful XBMC v12 media player and web browser. With HDMI 1.4a connectivity, you can connect the TS-251 to a HDTV to enjoy your rich multimedia content on the big screen. The splendid user interface and support for 7.1 channel surround sound audio passthrough bring smooth playback of Full HD videos providing a quality home theater experience. You can also turn your mobile devices into remote controls by installing the Qremote app or use QNAP RM-IR002 remote control and MCE remote controls via the built-in IR receiver of the TS-251 for convenient & easy control of the HD Station. Moreover, the HD Station supports YouTube Pairing, allowing you to select a YouTube video on your smartphone, tablet or computer and play it on HDTV via the TS-251.

Extend the functionality of the TS-251 with Virtualization
Introducing the world’s first consumer-grade NAS with integrated virtualization technology. The Virtualization Station transforms the TS-251 into a 2-in-a-box NAS that can function as an all-in-one NAS and a virtualization platform supporting multiple operating systems, fast virtual machine creation, virtual machine import/export, snapshot, and enables desktop operations on web browsers. With the easy-to-use interface, you can centrally manage all of the virtual machines created on the TS-251 with minimal effort. You can also download VMs on demand from online VM markets and import them to TS-251 without any complex procedure.
