About QNAP TS-851

The Qnap TS-851 1GB RAM 8-Bay Personal Cloud NAS provides a high performance & high capacity storage solution for SOHO & home, workgroup and SMB users. Powered by the advanced QTS operating system, the TS-851 performs as an easy-to-use yet powerful NAS for data backup, file synchronization, remote access, home entertainment and is ideal for users to build a personal cloud to access their data easily.

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-851 is a powerful home NAS with supreme value and great performance to deliver up to 220MB/s read & write speeds. The TS-851 can also automatically increase the processor's clock rate from 2.41GHz to 2.58GHz when needed for CPU-intensive tasks. The TS-851'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-851. When installed with the latest dual-band 2.4GHz/5GHz 802.11ac Wi-Fi network card, the TS-851 can offer remarkably high speeds for transferring large amount of files and streaming bandwidth-consuming multimedia.

QTS - Simple and efficient
Thanks to the intuitive user interface of QTS, system operations of the TS-851 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-851 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-851 wherever you are. Instantly stream or share your multimedia contents and share them with your friends.

Real-time & offline HD video transcoding
The TS-851 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-851 with on-the-fly hardware accelerated transcoding. The TS-851 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-851's performance running other applications. This also allows more people to play videos via streaming. The TS-851 also allows you to set a dedicated folder for automatic video transcoding.

You can also use the Qfile app on an iOS device to browse videos and photos stored on the TS-851 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-851's support for Plex Media Server organizes all of your media with rich information and transforms the TS-851 into a powerful & easy to use streaming machine with DLNA, Roku, Amazon Fire TV and Google TV support.
