The TS-431P3 4-Bay NAS Enclosure from QNAP has a 2.5 GbE RJ45 port that provides up to 2.5x the speed of Gigabit Ethernet and enables smooth multimedia playback and everyday usage. The TS-431P3 helps ensure data security through AES 256-bit encryption and various local, remote, and cloud backup options, including snapshot protection, which allows for files and data to be reverted to previously recorded states if they are accidentally deleted, modified, or affected by malware.

The TS-431P3 is powered by a 1.7 GHz Annapurna Labs AL-314 Quad-Core processor, which will allow you to run multiple applications simultaneously. The 2GB of DDR3 RAM has a configuration of 1 x 2GB, can be upgraded to 8GB using its one SO-DIMM slot, and will allow quick access to frequently used file and programs. Network connectivity is achieved using one 2.5 GbE port and one Gigabit Ethernet port, which support failover and dual IP. There is also support for JBOD, single disk, RAID 0, 1, 5, 6, and 10, each of which offers a combination of performance, 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 SSDs, and screws are included that accommodate each drive size. Using the three USB 3.0 Type-A ports this QNAP NAS can be connected to other devices, such as QNAP expansion units. To bolster security, AES 256-bit encryption helps to prevent sensitive business data from unauthorized access and breaches.

QNAP’s TS-431P3 4-Bay NAS Enclosure operates using an included 90W AC adapter that runs using 100-240 VAC. Also included is an Ethernet cable, 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

Build a Faster Home Network with QNAP
The TS-431P3 includes a 1GbE port and a 2.5GbE port to provide a smoother NAS experience and multimedia playback. Additional network connection options from QNAP include USB 3.2 Gen 1 to 5GbE adapters (supports N-BASET/Multi-Gig), QXG 5GbE PCIe cards, and QNAP QSW 10GbE switches. The TS-431P3 features three USB 3.2 Gen 1 port that delivers outstanding multitasking performance.

Easy and Secure File Management
File Station allows direct management of files stored on the TS-431P3 and in the cloud. Users can easily upload files from their PC, drag/drop files between folders, rename/delete files, and configure file/folder permissions to prevent unauthorized access. Users can also use Microsoft Office Online to directly view/edit Microsoft Office documents stored on the TS-431P3. Confidential/sensitive data can also be encrypted to add extra security.

Multi-Point File Backup, Access, and Sync
The TS-241P3 supports file sharing protocols (including SMB/CIFS, AFP and NFS) for Windows, Mac, and Linux/UNIX devices. Coupled with Qsync (a utility that transforms a QNAP NAS into a secure, high-capacity data center for file synchronization), any file uploaded to the TS-431P3 becomes available for all linked devices (such as computers, laptops, and mobile devices). Hybrid Backup Sync helps backup/synchronize data on the TS-431P3 to another QNAP NAS, remote server, or cloud storage for disaster recovery. Additionally, QuDedup technology greatly improves the efficiency of multi-version backup to destination storage, while optimizing storage utilization. You can install the QuDedup Extract Tool on your computer and restore deduplicated files to their normal status.

Protect Important Data with Snapshots
Snapshots help protect data by fully recording the NAS system state and metadata. With snapshots, users can quickly restore files to previously-recorded states if files are accidentally deleted or modified, or if the system is compromised by malware. 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.

Take Full Control of NAS System Status and Data Security
The Notification Center consolidates all QTS system events and alerts, providing a single-app solution for notifications. Security Counselor recommends actions and settings to improve the TS-431P3 security.

Stay Informed at All Times
The Notification Center offers a single-app solution for QTS system events and alert notifications. This removes the need to configure different app settings and helps users streamline management processes and save time.

NAS Security Portal
Security Counselor checks for weaknesses and offers recommendations for users to protect their TS-431P3. It also integrates antivirus and anti-malware software to ensure comprehensive data protection.

Comprehensive Surveillance Solution for 24/7 Security
Surveillance Station features a user-friendly interface and supports over 3000 IP cameras. With an expandable IP camera channel licensing system, users can build a comprehensive surveillance system for real-time monitoring, video and audio recording, and playback. Budget-conscious users can also save money on cameras by using USB webcams to record footage. Surveillance feeds can be monitored at any time by using the Vmobile app on mobile devices.

Extend NAS Functionality with Containers and Apps
Container Station integrates LXC and Docker lightweight virtualization technologies, allowing users to host and operate containerized applications directly on the TS-431P3. With many popular fully configured applications available from the built-in Docker Hub (including for automation and multimedia), the TS-431P3 provides users with a vast array of potential functions and application capabilities.

The TS-431P3 also features apps for backup/sync, content management, communications, downloading, and entertainment. Every app can be installed from the QTS App Center with a single click.

Multiply Your Productivity
The app-driven QTS operating system provides solutions for simplifying file backup, management, search, and more.

Centrally manage and switch between different email accounts, back up emails to the TS-431P3, and safeguard email security and personal privacy.

Notes Station 3
Notes Station 3 provides the advantages of collaborative note-taking with improved productivity to provide higher efficiency for your workgroup.

Smart Filing
Qfiling automates file organization. Files are automatically archived into folders based on your settings.

Full-Text Search

Easy Photo Management with QuMagie-Enabled AI Automated Photo Categorization
QBy integrating an AI deep-learning algorithm, QuMagie enables facial recognition, object identification, and geography tagging of photos on your NAS. Similar photos are grouped together in the AI Albums (i.e., People, Things, and Places). Other useful features include a built-in timeline scroll, customizable folder covers, and a powerful search tool, providing you with the ultimate photo management and sharing solution.

Flexible and Economical Storage Expansion
QNAP provides easy storage capacity expansion solutions. Here are several ways to expand the TS-431P3 storage to accommodate data growth:

Upgrade RAID Capacity
Hot-swap lower-capacity drives with larger-capacity drives to expand the TS-431P3.

Attach an Expansion Enclosure
