QNAP TS-435XEU-4G-US 4-Bay Rackmount NAS - 10GbE, NVMe SSD Ready

The QNAP TS-435XeU-4G-US is a 4-bay, 1U rackmount NAS built for businesses that need high-speed network storage in a compact footprint. Its short-depth chassis is designed to slot into shallow or half-depth racks where full-size servers simply will not fit, making it well suited for branch offices, retail back rooms, and edge computing deployments. Under the hood, a Marvell OCTEON TX2 quad-core ARM processor running at 2.2 GHz handles file serving, backup, and light virtualization duties, backed by 4GB of DDR4 RAM that can be expanded to 32GB as workloads grow.

Networking is a standout feature: dual 10GbE ports and dual 2.5GbE ports give administrators the flexibility to set up link aggregation for throughput, failover for resilience, or separate management and data networks entirely. Two M.2 PCIe Gen 3 x1 NVMe SSD slots let you add SSD caching to accelerate spinning-disk pools or create a dedicated all-flash storage tier for latency-sensitive applications. On the software side, QNAP's QTS operating system provides snapshot-based backup, Boxafe cloud backup for Google Workspace and Microsoft 365, Container Station for Docker workloads, and Surveillance Station for IP camera recording — all accessible through a browser-based management interface.
