Home NAS with quad-core ARM processor

The Qnap TS-433-4G-US is a compact four-bay server system built around an ARM Cortex-A55 quad-core 2.0 GHz processor with 4 GB DDR4 memory. It provides network connectivity through one 2.5 GbE port and one 1 GbE port for file storage and multimedia streaming.

Sustained workloads with hardware encryption

AES-NI 256 hardware-accelerated encryption secures full NAS volumes and shared folders while maintaining system performance during continuous read and write operations. The effective cooling fan keeps the unit cool and quiet under prolonged load.

Verify drive count and network infrastructure

This diskless chassis accepts four SATA drives, so confirm you have the required drives before ordering. Ensure your router or switch supports 2.5 GbE to utilise the faster port, and plan for the single 2.5 GbE and single 1 GbE uplink in your network topology.
