• Dual M.2 PCIe Gen 3 NVMe SSD slots enable cache acceleration or SSD storage pools for improved performance.
• Host multiple containerized apps to run a wide range of applications and services.
• Build a surveillance system with lower TCO and higher scalability with the subscription-based QVR Elite smart surveillance solution.
• Scale your storage capacity to fit growing data needs by connecting QNAP's expansion units.

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, audiovisual 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 ARMv8 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.

Future-proof your IT infrastructure for high-speed networks
QNAP provides comprehensive, budget-friendly storage and networking solutions, allowing you to easily and flexibly upgrade network environments for bandwidth-hungry applications.

A switch that supports 2.5GbE+
QNAP switches allow connecting multiple workstations and devices for high-speed 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.

SSD over-provisioning (Over-provisioning)
Add additional SSD over-provisioning to avoid write amplification and improve SSD random write speeds and endurance. You can potentially attain enterprise-grade SSD performance levels from affordable consumer-grade SSDs!

Host container applications
Container Station integrates Docker, LXD, and Kata Containers lightweight virtualization technologies. You can download apps from the built-in Docker Hub to easily import/export container apps and manage access controls, enjoying the benefit of easy installation, transferability and high-efficiency.

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.

PC/Laptop backup
For Windows, install NetBak Replicator to back up your PC to QNAP NAS. In macOS, just set up the built-in Time Machine to secure your data.

Remote backup for NAS
Hybrid Backup Sync makes it easy to back up data from a TS-435XeU to another QNAP NAS or remote server to fulfill your 3-2-1 backup strategy.

Cloud backup for NAS
Hybrid Backup Sync supports mainstream cloud storage for NAS data backup. For backup to object cloud storage, VJBOD Cloud is especially useful to reduce bandwidth usage and backup time.

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.

Volume and LUN snapshots
Take snapshots in seconds and revert the entire volume/LUN back to a specific point in time to prevent loss of important data.

Instantly restore snapshots
Snapshot content can be quickly restored to a local NAS, or restored on a folder/file basis to a local/remote NAS or cloud storage. You can also conveniently view and restore snapshots from the client side.

Back up snapshots
Multiply data protection by backing up snapshot files! Replicate volume/LUN snapshots in the TS-435XeU to a remote NAS (Snapshot Replica) by copying only the changes made. This helps save time & bandwidth, and can be run manually or on a scheduled basis.
