Product Overview

Qnap TS-435XeU-4G 4 Bay 1U Rackmount NAS

The compact and feature-rich TS-435XeU provides a professional-grade quad-core NAS solution in short depth rackmount form factor. The native 10GbE SFP+ and 2.5GbE connectivity alongside M.2 NVMe SSD slots that enable cache acceleration allows businesses to efficiently tackle everyday tasks like file backup/restore and to boost team collaboration with higher productivity. The space-efficient short depth design makes the TS-435XeU easy to install in small media cabinets or places with a lot of cabling. Supporting abundant business applications (including file sharing and sync, snapshot protection, containerization, cloud storage gateways, and video streaming), expandable storage capacity, and install-on-demand apps, the TS-435XeU is an ideal cost-effective entry-level rackmount NAS.

Smaller Footprint for Bigger Opportunities

Compared to a traditional 4-bay rackmount NAS, the compact TS-435XeU has a depth of only 11.49 inches (292 mm). This makes the TS-435XeU an excellent choice for smaller racks, and the unused space can be reserved for cabling or ventilation. The TS-435XeU is space-saving for flexible deployment and is especially suitable for multiple locations and applications including offices, audio-visual rooms, and security surveillance recording.

Robust Quad-Core 2.2 GHz Processor

The TS-435XeU is powered by an OCTEON TX2™ infrastructure Marvell® CN9130 series CN9131 ARM®v8 Cortex-A72 quad-core 2.2 GHz processor that features integrated workload-optimized hardware accelerators to meet performance, power and total cost of ownership requirements. The TS-435XeU comes with 4 GB DDR4 memory that can be upgraded to 32 GB for enhanced multi-tasking capabilities, and SATA 6 Gb/s support ensures maximum performance from storage drives.

Streamlined Workflows with High-Speed 10GbE and 2.5GbE

The TS-435XeU has two 10GbE SFP+ ports and two 2.5GbE RJ45 ports for high-speed networking to satisfy bandwidth-demanding applications (including massive file transfer, high-speed backup/restoration, containers, and multimedia transmission) with the support of port trunking and load balancing. QNAP's managed and unmanaged 2.5GbE/10GbE switches are a perfect match for organizations to build budget-friendly high-speed networks for productive team collaboration.

Get Performance Benefits from SSD Caching and Qtier Technology

To attain optimal I/O and reduce latency, you can configure SSD caching by using either 2.5-inch SSDs or the two built-in M.2 2280 SSD slots (supports high-performance NVMe PCIe Gen 3 SSDs, sold separately) in the TS-435XeU. Coupled with QNAP's SSD-aware features, the TS-435XeU maximizes performance with high cost-effectiveness.

A Multimedia Server for Video Streaming

The short depth TS-435XeU can be easily placed in a media cabinet. By installing streaming apps such as Plex® Media Server from the QTS App Center, you can stream media files stored on the TS-435XeU to mobiles and media streaming devices (including DLNA®, Roku®, Amazon Fire TV® and Google Chromecast™).

Comprehensive Backup and Disaster Recovery Solution

The TS-435XeU supports various apps that cover all your backup needs. Practice safe IT habits by regularly backing up files and device content, allowing them to be easily restored when needed.

Multi-Version Snapshots Mitigate Ransomware Threats

The TS-435XeU supports block-based snapshots that record the state of the system at any time. It helps protect data, which can be restored back to a specific point of time, greatly helping in mitigating the threat of ransomware.

Comprehensive Security and Privilege Settings

The TS-435XeU is loaded with flexible privilege settings and security measures. Besides IP blocking, 2-step verification, HTTPS connection, there are more apps that help ensure optimal NAS protection against threats like malware and hackers.

The Best File Storage and Collaboration Center

The TS-435XeU integrates rich apps for storing, managing, synchronizing, searching, and archiving files. It supports SMB/CIFS, AFP, and NFS protocols for streamlined file sharing across Windows®, Mac®, and Linux®/UNIX®, and provides the smartest NAS solution for professionally managing your files.

Smart Surveillance Solution for 24/7 Security

QVR Elite is QNAP's subscription-based smart surveillance solution, allowing you to easily build a surveillance system with lower TCO and higher scalability. Recordings are saved as MP4 files, allowing playback on nearly every device. QVR Elite also integrates QNAP AI-based solutions to build smart facial recognition for retail and door access systems with QNAP NAS. You can arrange a dedicated, independent storage space for surveillance data on the TS-435XeU and enjoy simplified camera management, storage space allocation, camera live viewing and playback.
