QNAP TS-435XeU Marvell OCTEON TX2 CN9130 / CN9131 ARMv8 Cortex-A72 4-core 2.2GHz processor, 4 GB SODIMM DDR4 (1 x 4GB)



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.

  • Dual-port 10GbE SFP+ connectivity accelerates intensive file access, large backup/restoration tasks, and media transfer.
  • Up to 5 Gbps transfer speeds can be made by setting port trunking with the two built-in 2.5GbE (2.5G/1G/100M) ports.
  • 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 QNAPs expansion units.
