QNAP TVS-H674T-I5-32G-US 6-Bay Thunderbolt 4 NAS

Overview

The TVS-H674T-I5-32G-US is a 6-bay QNAP Thunderbolt 4 NAS enclosure powered by an Intel Core i5-12400 6-core/12-thread processor with burst speeds up to 4.4 GHz. It delivers a maximum network bandwidth of 20 Gbps — enough throughput to handle simultaneous high-bitrate video ingest, editing, and backup without bottlenecking a multi-user creative or surveillance workflow. With support for up to 128 storage pools and a maximum volume size of 250 TB, it scales well beyond single-project storage into departmental or workgroup infrastructure. The 10/5 GbE network interface and USB 3.2 Gen 2 (10Gbps) ports mean you can connect both high-speed workstations and peripheral storage devices without a separate switch for routine transfers.

Compatibility

The TVS-H674T-I5-32G-US is compatible with Thunderbolt 4 hosts including modern Mac and PC workstations equipped with Intel Thunderbolt 4 controllers. The 10/5 GbE port integrates with 10GbE-capable network switches and is suitable for environments running NVR-backed IP camera archives or high-resolution video editing pipelines where storage I/O is the limiting factor. Volume types supported include Thick, Thin, and Static — giving administrators flexibility to pre-allocate capacity or provision dynamically depending on workload predictability. Note: maximum volume size of 250 TB requires at least 4 GB RAM (32 GB installed in this configuration exceeds that requirement comfortably).

Installation Notes

Deploy on a stable surface or rack shelf with adequate airflow — the i5-12400 generates meaningful heat under sustained NAS workloads. The 20 Gbps Thunderbolt 4 interface requires a certified Thunderbolt 4 cable and a host port that supports the full TB4 spec; connecting via a TB3 host will negotiate down to 40 Gbps TB3 bandwidth. Confirm switch port compatibility before connecting the 10/5 GbE interface — a 1GbE-only switch will cap throughput well below the NAS's capability.
