The TS-431X2 4-Bay NAS Enclosure from QNAP is an entry-level NAS for businesses looking for backup, restoration, private cloud, storage for virtualization. It also allows users to future-proof their IT infrastructure with a 10GbE SFP+ port for intensive data processing. It also supports Snapshots, which allow the NAS to be restored to a previous state in the event of an unexpected system failure or ransomware attack.

The TS-431X2 is powered by a 1.7 GHz Annapurna Labs AL-314 Quad-Core processor, which will allow you to run multiple applications simultaneously. The 8GB of DDR3 RAM has a configuration of 1 x 8GB and will allow quick access to frequently used file and programs. Network connectivity is achieved using the single 10GbE port or two Gigabit Ethernet ports which support failover and port trunking. There is also support for JBOD, single disk, RAID 0, 1, 5, 6, 10, and + hot spare, each of which offers performance, data redundancy, or a combination of both.

This 4-bay enclosure has the ability to natively house both 3.5" and 2.5" SATA III 6 Gb/s and SATA II 3 Gb/s hard drives or SSD drives, and screws are included that accommodate each drive size. When utilizing the 10GbE port, the TS-431X2 can deliver download speeds of up to 1014 MB/s and upload speeds of up to 580 MB/s. When using the 10GbE port with volume encryption, download speeds reach 357 MB/s and write speeds max out at 321 MB/s. Using the three USB 3.0 Type-A ports this QNAP NAS can be connected to other devices, such as QNAP expansion units. To help bolster security, AES 256-bit encryption helps to prevent sensitive business data from unauthorized access and breaches.

QNAP's TS-431X2 4-Bay NAS Enclosure operates using an included 90W AC adapter that runs using 100-240 VAC. Also included are two Ethernet cables, a power cord, 3.5" HDD flat head screws, 2.5" HDD flat head screws, and a power cord. Protection is provided by a limited 2-year warranty.

General Features

1.4 GHz Alpine AL-314 Quad-Core Processor

With a 10GbE SFP+ LAN port and two Gigabit LAN ports, the TS-431X2 provides speeds of up to 1014 MB/s to meet the needs of bandwidth-demanding tasks. Supporting AES 256-bit volume-based data encryption, the TS-431X2 provides excellent speeds of up to 357 MB/s while ensuring the confidentiality of sensitive business data stored in the NAS.
Integrated 10GbE SFP+ Port
The TS-431X2 not only provides two Gigabit Ethernet ports, but also one 10GbE SFP+ port to fully support 10GbE high-speed networks. 10GbE is capable of delivering fast throughput for businesses that demand higher bandwidth for virtualization and fast backup & restoration for an ever-growing amount of data.
SSD Cache Acceleration
The TS-431X2 supports SSD caching to boost the IOPS performance of storage volumes and increase operational efficiency. It is suited for improving the overall workflow of IOPS-demanding applications and allows the best of both cost and performance by combining SSDs with HDDs.
Disaster Recovery with Snapshots
The TS-431X2 supports block-based Snapshots, which can record and save the state of the file system and the metadata of the files outside the file system. In the event of an unexpected NAS failure or if struck by a ransomware attack, the snapshots remain intact, allowing you to quickly and easily restore the system back to a previous normal state. You can preserve and restore multiple versions of the same file, folder, or even the entire volume. The TS-431X2 supports up to 64 snapshots per volume or LUN (up to 256 in total). Snapshot Replica facilitates double protection that replicates snapshots to a remote QNAP NAS or server.
Container Station
Container Station integrates LXC and Docker lightweight virtualization technologies, allowing you to operate multiple isolated Linux systems on the TS-431X2, as well as download apps from the built-in Docker Hub Registry for unlimited containerized applications. What's better, Container Station supports the QIoT Containers platform that helps quickly structure your IoT environment and deployment on your private IoT cloud, boosting microservices and modernizing legacy applications to drive more business opportunities.
Qfiling Automates File Organization
Qfiling helps automate file organization for sorting files spread through multiple folders, helping reduce the time needed to find important files. Users can categorize files, determine filing conditions, and schedule filing tasks to be carried out periodically. The "Recipe" feature allows users to save frequently-used filing conditions as an "exclusive recipe," then the next Qfiling task can be run with just one click using the recipe.
The TS-431X2 supports Qsirch, a search tool for quick file searching. Qsirch supports thumbnail previews and even remembers your search history, allowing you to quickly navigate to files you've previously searched for. The revamped Qsirch adds "search operators" and advanced search filters and tags, allowing you to find files faster with more precise results. Qsirch also provides a Helper for Google Chrome and Mozilla Firefox that allows you to search for files on your NAS when you use Google Search.
Centralized Email and Contact Management for Improved Communication Workflows
It can be hard to manage emails and contact information that are scattered across multiple computers, devices, and accounts - not to mention if important emails or contact information are lost or become inaccessible due to account closure or device malfunction/loss. QNAP QmailAgent and Qcontactz helps you centrally store and manage emails and contact information, making them accessible to your devices. Using the powerful Qsirch search engine, you can easily find specific contacts and emails whenever needed.
Notes Station
Notes Station helps organize notes for your personal and working life. You can easily edit text, insert images/files from the NAS, fine-tune images with the image-editing tool, create sharing links to share notes, backup/restore your notes with snapshots, and ensure privacy with password protection and encryption. You can also invite people to collaborate on notes for greater teamwork. Notes Station provides a safe and convenient way of taking notes that are fully under your control on your TS-431X2's private cloud.
QTS 4.3 Operating System
With modularized multiple applications and functions, QTS enhances management efficiency, personal productivity, multimedia, and much more. Intelligent agent services have also been added to simplify system operations and management. The user-friendly QTS features an intelligent desktop that allows you to find desired functions quickly, monitor important system information on a real-time basis, open multiple application windows to run multiple tasks concurrently with greater working efficiency, and provides a built-in App Center with install-on-demand apps to extend NAS functionality.
VPN & Proxy Server
QVPN combines VPN server and VPN client functionality. Through QVPN, the TS-431X2 can be used as a VPN server with L2TP/IPsec, OpenVPN, and PPTP support, allowing you to securely access data shared within the private local network. The TS-431X2 can also be used as a VPN Client to connect to other VPN servers or virtual private network through PPTP and OpenVPN for secure data transmission. VPN Client also allows your NAS to connect to multiple servers at the same time. You can connect your devices to your NAS and the VPN server at home to access data on the LAN and via VPN Client on your NAS, you can connect to international VPN servers for accessing regionally-restricted services such as Netflix and Hulu in HD Station. The TS-431X2 provides you with various VPN options and helps secure your data transmission.
Share and Sync Files Across Devices
The TS-431X2 supports SMB, NFS, and AFP, allowing you to quickly share files to Windows, Mac, and Linux/UNIX devices.

The TS-431X2 provides numerous security options, such as antivirus, encrypted access, IP blocking, 2-step verification, and more. IT administrators can also control the access rights of each user to different folders, preventing unauthorized access to important files. The TS-431X2 supports AES 256-bit encryption, preventing sensitive business data from unauthorized access and breach even if the hard drives or the entire system were stolen. Windows AD server, LDAP server, and built-in LDAP service are also supported.
Surveillance Station
Surveillance Station is a professional network surveillance Video Management System (VMS) that offers a user-friendly management interface, over 3000 compatible IP camera models, and expandable IP camera channel licenses. It supports real-time monitoring, video & audio recording, and playback with a wide range of customizable settings. You can use the iOS or Android Vmobile app to manage the monitored channels to safeguard your office environment, or install the Vcam mobile app to turn your device into a network camera to record to your TS-431X2. The TS-431X2 offers 2 free IP camera channels and you can expand up to 30 channels by purchasing additional licenses.
Virtual JBOD
Besides using physical storage expansion enclosures, there is an additional option to expand NAS storage capacity. QNAP VJBOD (Virtual JBOD) is network-based JBOD, allowing you to expand the storage of a QNAP NAS by using the unused storage space of another QNAP NAS. The TS-431X2 supports VJBOD to economically expand the storage capacity of other QNAP NAS devices with its unused storage space. You can also create virtual storage pools and volumes on the virtual disks for operating NAS services.
Expand Storage Capacity
The TS-431X2 supports online capacity expansion by connecting two QNAP expansion enclosures for storing rapidly-growing data, which is well-suited for storage-intensive applications such as video surveillance, data archiving, TV broadcast storage, and more. You can gradually expand the TS-431X2's storage on demand, and use the QTS Storage Manager to easily handle the NAS capacity expansion and storage expansion enclosure management. With the support of QJBOD Express (JBOD enclosures roaming), you can just connect a large capacity QNAP expansion enclosure to the TS-431X2, and migrate data to another NAS through the JBOD enclosure without network connectivity.

The TS-431X2 is compatible with the UX-500P and UX-800P expansion enclosures. When using one UX-500P enclosure, up to 9 total drives (NAS + enclosure) are supported, while adding a second UX-500P supports 14 total drives. If you need more storage, adding one UX-800P provides users with 12 total drives and adding a second UX-800P increases that number to 20.

    TS-431X2 4-Bay NAS Enclosure is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Customer Service Is Great! First, I am not well versed in this type of backup system so I needed a fair amount of help with understanding how this system works. I just got off the phone during the 4th or 5th remote session with the customer service rep and I am very pleased! He helped me set the system up and understand several nuances. I had purchased a Synology unit similar to this one and customer service was very poor. Customer service is key!
