QNAP has launched the TS-435XeU 4-bay NAS powered by a Marvell OCTEON TX2 CN9131 quad-core 2.2 GHz processor. Featuring a 1U short-depth chassis, the TS-435XeU is an entry-level rackmount NAS that finds a nice balance between cost and performance. It comes equipped with dual 10GbE and dual 2.5GbE ports, two M.2 PCIe Gen 3 NVMe SSD slots, storage scalability, and both business and media features. QNAP indicates that the TS-435XeU is ideal for media and comms equipment cabinets.

Two M.2 NVMe SSD slots can be used for caching to boost application performance and reduce latency, or Qtier auto-tiering to maximize storage utilization and efficiency. The TS-435XeU’s storage capacity is scalable by connecting the NAS to QNAP storage expansion units.
Other features of the new TS-435XeU include:
- Qsync support, which helps to streamline cross-team file sync.
- Block-based snapshots, ensure data protection, provide instant restoration, and can help protect against the impact of ransomware attacks.
- HBS (Hybrid Backup Sync), which facilitates local/remote/cloud backup tasks enclosures.
In addition, the TS-435XeU users will have access to QNAP’s built-in App Center, which allows users to do things like host containers, deploy a cloud storage gateway, and implement a professional video surveillance system.
