    Quad-core CPU drives higher performance

    The TS-431K is powered by a quad-core 1.7 GHz CPU that features more CPU cores to enhance system performance. With 1 GB RAM, two Gigabit LAN ports, and SATA 6 Gb/s drives, the TS-431K delivers high performance, while also maintaining data security. The TS-431K also features three USB 3.2 Gen 1 ports, allowing you to transfer large media files between the NAS and your devices. The USB port on the front panel supports one touch copy, making it convenient for you to backup data on your external device to a NAS or vice versa with just one click.

    Easily Create a High-speed Network Environment

    You can use QNAP USB 3.2 Gen 1 on 5GbE adapters (QNA-UC5G1T) with the TS-431K or your computer. By connecting the NAS and PC through the 5GbE adapters, you can create a 5GbE network connectivity for nearly 300 MB/s transfer speed.

    Boost productivity with QNAP applications

    QNAP File Station provides centralized file management, allowing you to view and manage files on your TS-431K and other storage sources or external devices, which allows you to easily share files with family and friends through email, social media, or share link. You can also use Qfile mobile app to access NAS files from a mobile device.

    File Station

    File Station allows you manage files stored on your QNAP NAS in your cloud space, or from USB card reader and mobile devices. You can easily access all your data from a single application.


    Qfile mobile app allows you to access NAS files from a mobile device anytime anywhere, while uploading and backing up files on your phone to a NAS.

    Protects your sensitive data with file encryption

    When sharing sensitive or confidential files on your TS-431K, you can enhance data security with File Station by encrypting files into .qenc files and set a password. The file recipients need to download and install QENC Decrypter on their computers and enter the correct password to decrypt, view, and use encrypted .qenc files.
