The TS-431 supports SMB/CIFS, NFS, and AFP protocols for file sharing across Windows, Mac and Linux/UNIX. Data, logs and ISO image of CDs and DVDs can be centrally stored in the TS-431 and protected by an integrated antivirus solution.



Manage your files via the Internet

The File Station brings conventional desktop-style file operations to web browsers, allowing you to upload, download, and manage files on your TS-431 wherever there is an internet connection. Supporting file extraction, folder creation, and smart search for files and folders, File Station also allows you to easily share files with friends & family via unique URLs. With reliable security features, SSL and password options, managing & sharing your files is simple and safe with the File Station.



A private cloud without constraints

In contrast to the limited storage space and potential security concerns of public cloud services, the TS-431 is advantageous for establishing a secure and large-capacity private cloud. The myQNAPcloud service allows remote access to files stored on the TS-431, allowing you to play & share multimedia from the TS-431 or to conveniently check the system status from anywhere.



Create digital notes on your private cloud

Notes Station provides a private & secure way to share and collaborate on digital notes. With just a few steps you can create notes from web pages (or by importing from the TS-431), edit notes with the intuitive web-based editor, and take screenshots for quick note-taking with Qsnap or the Notes Station Clipper extension for Chrome. You can also easily leverage the rich media contents stored on the TS-431 to enhance your notes, and access them on your mobile phones or tablet devices by using Qnotes mobile app anytime, anywhere.

With flexible privilege settings for editing & sharing notes, you can build a secure environment to work together with friends and colleagues. In addition, the Notes Station enables you to create to-do lists & calendar alerts that can be updated to your Google Calendar, helping manage your daily tasks more efficiently.


Archive your photo memories. Share your life.

The TS-431 acts as your photo vault for you to back up your favorite photos. The Photo Station makes photo sharing simple, and you can designate your own access right controls. Simply upload your photos to the TS-431 to create & organize your photo albums through a web browser, and share with your family and friends through social networking sites such as Facebook, Google+, Twitter and Pinterest. With the Qfile mobile app (for iOS and Android) you can also instantly upload your new photos from your mobile device to the TS-431.


Build your home music library and enjoy music anywhere

The Music Station helps categorize your music collection, and displays album covers to easily organize your personal playlists. Through the music station web player, you can enjoy your music anytime, anywhere with a few clicks. Thousands of local and global online Internet radio programs are also built-into the Music Station for you to enjoy.


  • Listen to your favorite songs streamed from iTunes Server, or play music via web browsers on your PC.
  • Stream music to DLNA-compatible music systems for a high-quality sound experience.
  • Stream music via AirPlay to compatible devices.
  • Listen to your music on mobile devices through the Qmusic app.



Supports DLNA and AirPlay for media streaming

You can use DLNA-compatible devices such as Smart TVs, Sony PS3, Microsoft Xbox 360 and media players to enjoy HD quality videos stored on the TS-431. You can also use the Qfile app on an iOS device to browse videos and photos stored on the TS-431 and play on the TV via Apple TV. By installing the QAirplay app from 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.



Offline Video transcoding

With offline transcoding, if you can only connect to a slow, limited or restricted Internet connection, you can still enjoy smooth video streaming by playing a version of the video with a pre-rendered, optimized resolution. By setting an automatic transcoding folder, the TS-431 will automatically convert the videos in this folder to a range of resolutions for use on many different devices and internet speeds. As this transcoding is a background task, you can schedule the TS-431 to work during off-peak hours such as when you are at work or asleep, allowing you to enjoy a perfect stream of your favorite videos when you're off work or wake up.

* The offline transcoding capability of the TS-431 is 3 times faster than single-core ARM-based NAS.


24/7 download center

The TS-431 is a perfect download center for high speed BT, Magnet, PT (Private Trackers), eMule, FTP, and HTTP downloads. After the download tasks are set ready, you can turn off the computer, and the TS-431 will download as many HD videos as you want. With the QGet utility you can manage your download tasks on multiple Turbo NAS devices remotely on the local network or the Internet. You can also install HappyGet app to back up abundant online videos to your TS-431.



Dropbox-like file synchronization across computers and mobile devices

With Qsync, your TS-431 is turned into a safe data center for file synchronization. Any file uploaded to the TS-431 will be made available for all linked devices, such as computers, laptops and mobile devices. Qsync is especially useful for frequent travelers in managing files and ensuring that different devices have the most up-to-date files. Qsync provides multiple ways for file synchronization and group file sharing, greatly enhancing the flexibility of team projects and collaboration.


Access, use, sync and enjoy with your tablets and smartphones

The TS-431 is your private cloud storage that virtually enlarges the capacity of your mobile devices. Qfile allows you to access, upload, download, manage, and share stored files easily as if you are all of your files in your pocket. If Qfile is installed on an iOS device, users can also browse videos & photos stored on the TS-431 and play via Apple TV. Qmanager lets you monitor & manage the TS-431 remotely and efficiently without turning on your PC, while Qmusic allows you to stream or download music from your TS-431 to mobile devices.



Comprehensive surveillance solution providing 24/7 security

The TS-431's Surveillance Station offers a professional surveillance solution with a user-friendly management interface, a wide range of over 2,700 compatible IP camera models, and default 2 free IP camera licenses that can be expanded up to 8 camera channels by purchasing additional licenses.

You can also install the VMobile app on your iOS or Android devices to manage the monitoring of cameras anytime, anywhere, for total surveillance of your monitored environment.



Install-on-demand apps to extend NAS functionality

The TS-431 has a built-in App Center that provides various install-on-demand apps developed by QNAP and third-party developers, including tools for backup/sync, business, content management, communications, download, entertainment, and much more. It is also a centralized location for managing & updating installed apps. In addition, QNAP's development platform embraces the open-source spirit to enable developers to create their own apps, adding potentially limitless opportunities for the TS-431.


Enhance productivity with eSATA and multiple USB 3.0 ports

Equipped with an eSATA and three SuperSpeed USB 3.0 ports, the TS-431 allows you to flexibly arrange tasks with a wide range of external devices without interrupting your current workflow. You can back up files to USB drives & eSATA enclosures, access data stored on SD cards via USB card readers, share up to 3 printers via network, and connect to a UPS to ensure a continual power supply.



The TS-431 features an energy-efficient dual-core ARM processor that maintains high performance in system operations and is suitable for an always-online personal cloud without running up a high electricity bill.
