Key Features

Quad-core ARM processor at 2.0 GHz
4 GB DDR4 system memory
4-bay desktop NAS form factor
10GbE SFP+ host connectivity
2.5GbE network support
PCIe Gen3 expansion slot

Keep critical business data close, fast, and protected with a 4-bay NAS designed for efficient branch and SMB storage. The TS-432X pairs an ARM-based quad-core 2.0 GHz processor with 4 GB DDR4 memory and hardware encryption, giving you a practical platform for file sharing, backup targets, and secure data retention. Network performance is a clear differentiator. Native 10GbE SFP+ and 2.5GbE connectivity help reduce bottlenecks for multi-user access, while the PCIe Gen3 expansion slot provides a path for future interface or function upgrades. That matters when you need a system that can handle today’s workloads without forcing a full replacement later. This model is a strong fit for teams that want more than basic storage. It supports a disciplined deployment approach: centralize files, protect sensitive data, and expand capabilities as requirements grow. For organizations comparing entry-level NAS appliances, the TS-432X stands out by combining encrypted storage, faster networking, and expansion headroom in a compact desktop footprint.
