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 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.

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.

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 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.

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.

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.

QNAP NAS provides a simple solution for backing up/restoring laptops and desktops. You can use QNAP NetBak Replicator to backup files on Windows® computers, including Outlook® Email archive. The NAS also supports Time Machine® on Mac® devices, enabling easy, fast, and convenient data backup.
