Purpose and audience
The Qnap TVS-h674-i3-16G-US is a six-bay desktop NAS built around an Intel Core i3-12100 processor with four cores and eight threads. It ships with 16 GB of DDR4 memory installed and supports up to 64 GB across two SODIMM slots. The platform targets small businesses and creative teams that need ZFS-based data integrity, inline deduplication and near-limitless snapshots for file serving, virtualization or collaborative video editing.
Build, connectors and daily use
The chassis accepts six 3.5-inch or 2.5-inch SATA drives and provides two M.2 PCIe Gen 4 slots for NVMe caching. Front-panel LEDs show status for each drive bay, LAN, USB and M.2 devices. Networking consists of two 2.5 GbE RJ-45 ports, while external expansion uses one USB 3.2 Gen 2 Type-C and two Type-A ports, all at 10 Gbps. An HDMI 1.4b output and PCIe Gen 4 slots allow display or add-in card flexibility.
Thermals, noise and power
Operating temperature range is 0 to 40 °C with 5 to 95 % non-condensing humidity. Typical power draw with a full set of drives is 79.363 W, dropping to 39.911 W when the disks are in sleep mode. The 250 W internal supply handles 100 to 240 V input. Buyers who need more than six drive bays or 10 GbE networking built in will need a different platform.

Questions about this item
What speed does the 2.5GbE port actually cap at for file transfers?
Each RJ-45 port runs at 2.5 GbE, so sustained throughput tops out around 2.5 Gbps per connection.
Which drive sizes and tray count does the chassis accept?
Six hot-swap bays take 3.5" SATA HDDs or 2.5" SATA SSDs, no caddies needed.
How do I add RAM and what slot mistake should I avoid?
Open the case, insert DDR4 SODIMM modules into the two slots; populate both channels for dual-channel performance.
