Product information

Description

The QNAP TS-435XeU is a short-depth 1U rackmount 4-bay NAS powered by a Marvell CN9131 quad‑core 2.2 GHz processor and 4 GB DDR4 memory (expandable). Designed for small and medium businesses, it supports 2.5GbE RJ45 and 10GbE SFP+ network connectivity, M.2 NVMe SSD caching, and SATA 6 Gb/s drives. The compact chassis (292 mm depth) enables installation in shallow racks or media cabinets while providing features for file sharing, backup, snapshots, container hosting, multimedia streaming, and scalable storage expansion.

Advantages

The TS-435XeU delivers high-speed networking with two 10GbE SFP+ ports and two 2.5GbE RJ45 ports, integrated M.2 NVMe SSD slots for cache acceleration, and Qtier-enabled tiering to optimize performance and storage efficiency. Its short-depth 1U form factor saves rack space and simplifies deployment in constrained environments. Built-in snapshot protection, Hybrid Backup Sync, security tools (including VPN, firewall, malware removal, and security audit), and support for various business apps provide an all-in-one solution for backup, collaboration, and surveillance storage.

Suitable for

  • Small and medium business file servers and team collaboration
  • High-speed backup and large file transfers
  • Media server and streaming in compact racks or cabinets
  • Edge or branch office deployments with limited rack depth
  • Surveillance storage with dedicated allocation and playback

Key specifications

  • Model: TS-435XeU (MPN: TS-435XEU-4G)
  • Form factor: 1U short-depth rackmount (depth 292 mm)
  • Drive bays: 4 (HDD/SSD, no drives preinstalled)
  • Processor: Marvell CN9131 (ARM v8 Cortex‑A72) quad‑core 2.2 GHz
  • Memory: 4 GB DDR4 (expandable, up to 32 GB)
  • Storage interfaces: SATA 6 Gb/s; 2 x M.2 2280 NVMe slots (for SSD cache, SSDs sold separately)
  • Networking: 2 x 10GbE SFP+, 2 x 2.5GbE RJ45
  • RAID: supported (configurable via QTS)
  • Weight and color: approx. 4.17 kg; black/grey chassis

How to use

Install your chosen HDDs or SSDs into the four drive bays and optionally add NVMe SSDs into the two M.2 slots to enable SSD caching. Connect the TS-435XeU to your network using the 10GbE SFP+ or 2.5GbE RJ45 ports; configure link aggregation or load balancing if required. Use QNAP QTS to create volumes/RAID groups, set up shared folders and user permissions (SMB/CIFS, NFS, AFP), and enable services such as Hybrid Backup Sync, snapshots, Container Station, and multimedia streaming apps (for example Plex). Manage backups from Windows (NetBak Replicator) or macOS (Time Machine) and configure remote or cloud backups using Hybrid Backup Sync or VJBOD Cloud.

Usage recommendations

For improved responsiveness with IOPS‑heavy tasks, provision NVMe SSDs in the M.2 slots or use 2.5-inch SSDs for cache acceleration, enable SSD over‑provisioning when supported, and consider expanding memory for heavy virtualization or container workloads. Place the TS-435XeU in a well-ventilated shallow rack or cabinet and use QNAP’s security features (two-step verification, QuFirewall, QVPN, Security Counselor) to protect remote access and stored data.
