Sku: TS-431KX-2G-US

The quad-core TS-431KX provides four drive bays for high-capacity storage and memory expansion up to 8GB RAM. With the built-in 10GbE SFP+ port, the TS-431KX delivers high bandwidth required for intensive data transmission. Coupled with the QNAP 10GbE switch, you can easily build a high-speed 10GbE network environment with an affordable budget. The TS-431KX provides comprehensive local, off-site and cloud backup and supports Snapshot technology to help you create a reliable backup and disaster recovery plan. In the event of a system crash or accidental deletion of files, you can quickly restore the system to its normal state. The TS-431KX comes with lockable drive trays, ensuring the drives will not be accidentally removed or fall out and cause data loss.

Single-port 10GbE connectivity enhances transfer speed for intensive data transmission and shortens backup time.

HBS (Hybrid Backup Sync) can backup and sync your data to other NAS, servers and cloud storage for comprehensive backup and disaster recovery.

Snapshots fully record system status and data, allowing you to protect files and data from accidental deletion and malware attacks.

Supports LXC and Docker® containers for rapidly deploying application services across platforms, including the cloud, servers, and PCs.

Hot-swapping design allows you to remove hard drives without powering off the NAS to ensure continuous operations.


Supports VJBOD (Virtual JBOD) technology to expand the storage space of other QNAP NAS.

High-speed 10GbE and 2.5GbE connectivity

Powered by AnnapurnaLabs AL-214 quad-core 1.7 GHz processor with 2 GB DDR3L RAM (single memory slot, expandable to 8 GB), the TS-431KX features one 10 GbE SFP+ port and two Gigabit ports for high-speed data transfer. Coupled with QNAP QSW series network switch, you can easily upgrade your network environment to 10GbE affordably to enjoy streamlined workflow.

Easily Create a High-speed Network Environment

10GbE improves overall network performance and everyday tasks with ten times the bandwidth of 1GbE. From 10GbE NAS, to switches, to network adapters, QNAP provides a complete range of everything needed to upgrade to 10GbE environments.

Multi-point file backup, access and sync

HBS (Hybrid Backup Sync) consolidates data backup, recovery, and data synchronization, integrated with the TS-431KX high-speed 10GbE connectivity, you can easily backup or sync data to another QNAP NAS, remote server or cloud storage to build a reliable disaster recovery solution. Qsync turns the TS-431KX into a secure, high-capacity data center for file synchronization. Any file uploaded to the TS-431KX 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.

Boost productivity with QNAP applications

QNAP File Station provides centralized file management allowing you to view and manage files on your TS-431KX and other storage or devices (such as USB storages or mobile devices). Qfiling can help you automate file organization, while Qsirch can accelerate file searches. You can also use the Qfile mobile app to access NAS files from a mobile device.

Protects your sensitive data with file encryption

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

Note: Computers are required with Windows 8 (or later) OS and macOS 10.12 (or later) OS.

Protect data against malware with Snapshots

Snapshots help protect your data by fully recording the NAS system state 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 modified data. Not only does this save storage space, but it also reduces the time required to back up and restore data. The TS-431KX supports up to 32 snapshots per volume or LUN, and up to 64 snapshots in total.

Extend hardware warranty up to 5 years

The TS-431KX is backed by a 2-year warranty at no extra cost. You can purchase a warranty extension to extend your warranty coverage up to five years.

QM2 - Upgrade your QNAP NAS Experience with M.2 SSD Caching and 10G in One Card

QM2 is designed specifically to upgrade your entry and mid-end QNAP NAS system! QNAP puts 2 M.2 SSD slots (SATA or PCIe NVMe) and one 10GBase-T network port into a single PCIe expansion card. Installed M.2 SSD sticks are covered by a giant heatsink as well as a smart fan for heat dissipation which ensure operational stability and longevity. With this PCIe expansion card, you can enable SSD Caching or auto tiering while populate all your NAS bays with high capacity HDD!

Application for QM2 SSD slots:

  1. Create a volume on these SSD and use them as extra storage
  2. Enable Read Cache
  3. Enable Read/Write Cache
  4. Enable Qtier feature
  5. Boost performance in case of memory swapping

What is Qbit?

Configured system orders start here!
The selected drives are batch controlled and tested using our HDD and SSD servers. Passed drives are then installed in the NAS with Volume and RAID set. Our pre-burn testing prepares the NAS with an initial system and drive testing cycle to ensure that the integrity of the entire system is tested and passed with no issues at all.

Our stress testing (burn-test) cycle commences for a minimum of 24 hours and extends to 48 hours if requested or required. This is undertaken in order to ensure stability when used in a normal environment. These tests can include extremes of workload (constant I/O's), CPU and memory use, thermal load (heat), clock speed, or voltages, bus and connectivity components, with the primary stress testing software aiming to test stability by trying to force a system to fail. Our tests put a greater emphasis on robustness, availability and error handling heavy loads.

Once the tests are complete we QA and pack the system back into it's retail box. Then it's double boxed to protect the unit during shipping. You receive your QNAP NAS Ready To Plug 'N' Store. It doesn't get any easier. Buy your NAS from the QNAP EXPERTS at QNAP DIRECT.
