Features:

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

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.

Note: The computer must run on Windows 8 (or later) or macOS 10.12 (or later).

Protect data against malware with Snapshots

Snapshots help protect your data by fully recording the NAS system status and metadata. If a file is accidentally deleted or modified, you can use snapshots from the Storage & Snapshots Manager or the File Station to quickly restore files to its previously-recorded state. QNAP snapshots are block-based and only record changed data. Not only does this save storage space, but it also reduces time required to back up and restore data. The TS-431K supports up to 16 snapshots per volume/LUN, and up to 32 snapshots in total.

Multi-point file backup, access, and sync

HBS (Hybrid Backup Sync) consolidates data backup, recovery, and synchronization, allowing you to easily backup or sync data to another QNAP NAS, and remote server or cloud storage (e.g. Dropbox® or Google® Drive) to build a reliable disaster recovery solution. Qsync turns the TS-431K into a secure, high-capacity data center for file synchronization. Any file uploaded to the TS-431K will be made available for all linked devices, such as computers, laptops, and mobile devices. You can also sync shared folders or create team folders to enhance team collaboration.
