Product Description

TS-435XeU
4-bay low-profile rack-mounted NAS supporting 2.5GbE/10GbE connectivity and M.2 NVMe SSD cache

The compact and feature-rich TS-435XeU offers a professional quad-core NAS solution with a low-profile rack-mounted form factor. Native 10GbE SFP+ and 2.5GbE connectivity with M.2 NVMe SSD slots that enable cache acceleration allows businesses to efficiently handle daily tasks such as backup/restoration and boost team collaboration with superior productivity. The low-profile design makes it easy to install the TS-435XeU in small media cabinets or in areas with heavy cabling. Supporting numerous professional applications (including file sharing and synchronization, snapshot protection, containerization, cloud storage gateways, and video streaming), the expandable storage capacity and on-demand installable apps make the TS-435XeU an ideal and cost-effective entry-level rack-mounted NAS.

A smaller footprint for greater opportunities
Compared to a traditional 4-bay rack-mounted NAS, the compact TS-435XeU has a depth of only 11.49 inches (292 mm). Thus, the TS-435XeU is an excellent choice for small cabinets, while unused space can be reserved for cabling or ventilation. The TS-435XeU saves space to gain flexibility in deployment. Furthermore, it is particularly suitable for multiple sites and activities, including offices, audiovisual rooms, and video surveillance recordings.

Robust 2.2 GHz quad-core processor
The TS-435XeU is powered by a Marvell® quad-core processor under the OCTEON TX2™ CN9131 ARM® v8 Cortex-A72 family at 2.2 GHz, which includes built-in hardware accelerators with optimized workloads to meet performance, power, and total cost of ownership needs. The TS-435XeU comes with 4 GB of DDR4 memory, which can be expanded to 32 GB to enhance multitasking capabilities, and the SATA 6 Gbit/s support ensures maximum performance from storage drives.

Simplified workflows with high-speed 10GbE and 2.5GbE
The TS-435XeU features two 10GbE SFP+ ports and two 2.5GbE RJ45 ports for a high-speed network to meet bandwidth-intensive applications (including large file transfers, fast backup/recovery, containers, and multimedia streaming) with support for port aggregation and load balancing. QNAP's manageable and unmanaged 2.5GbE/10GbE switches are perfect for organizations to deploy cost-effective high-speed networks for productive team collaboration.
