TS-435XeU
Short depth rackmount 4-bay NAS, supporting 2.5GbE/10GbE connectivity and M.2 NVMe SSD caching

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, 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 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.
