TVS-h674-i3-16G: specifications and dated store comparison →Six-bay i3-12100 / 16 GB QuTS hero NAS for ZFS file service, not a 10GbE workstation.
Exact US MPN TVS-h674-i3-16G-US; official hardware table TVS-h674-i3-16G; 16 GB SODIMM DDR4; 6 x 3.5-inch SATA 6Gb/s, 3Gb/s.
Based on the official TVS-h674 hardware/software tables (OS rows labelled QTS 5.2.9 / QuTS hero h5.2.9), a separately sourced QuTS hero h6.0.2.3591 (2026-08-24) applicable-models list, and 2 applicable original review record(s). We have not tested this NAS. Related other-SKU tests stay labelled related. See the review evidence ↓
Official i3-12100, 16 GB SODIMM DDR4, six SATA bays and QuTS hero/ZFS.[1]
Tom's Hardware Italia only measured one WD Red Pro over Gigabit; 2.5GbE and RAID were unused.[3]
16 GB and four P-cores are a weak default for stacked VMs; look at i5/i7 or the 877AX if that is the job.[1]
Follow any specification for its full conditions and sources.
Living with it
This page covers TVS-h674-i3-16G-US, mapped to official table TVS-h674-i3-16G. CPU: Intel® Core™ i3-12100 4-core/8-thread Processor, burst up to 4.3 GHz. Factory memory: 16 GB SODIMM DDR4. Drive bays: 6 x 3.5-inch SATA 6Gb/s, 3Gb/s. US store SKU TVS-h674-i3-16G-US matched the opened manufacturer PDP.[1][2]
The hardware spec page still publishes QTS 5.2.9 and QuTS hero h5.2.9 feature tables; those rows stay version-bound. QuTS hero h6.0.2.3591 (build 20260819, notes dated 2026-08-24) lists TVS-h474/TVS-h674/TVS-h874/TVS-h874X/TVS-h674T/TVS-h874T as applicable. TVS-h674 is in that family string. Exact -i3/-i5/-i7/-i9/-R5 RAM SKUs are not itemized. This page does not claim every 5.2.9 table feature is unchanged on h6.0.2.[1][6]
Advertised port speed is not one-file throughput. Drive count, RAID, protocol, client NICs and the switch each cap the result. Independent 9 Gbit/s-class numbers in this family used add-in 10GbE, not the stock 2.5GbE pair.[1]
Our buying advice combines official specifications with the original reviews below. We have not tested this product ourselves. Expand a review for its setup, measurements and limitations.

Profesional Review's QNAP-loaned unit was the i3-12100 with 16 GB DDR4-3200 and QuTS Hero. Useful for identity and cooling notes, not RAID MB/s.

Before you buy
Budget for drives, a UPS and a separate backup target. Faster Ethernet requires compatible network hardware; Thunderbolt models also need a suitable host and cable.[1]

No. Those strings are the OS rows on the current hardware spec tables. A later published branch, QuTS hero h6.0.2.3591 build 20260819 (2026-08-24), lists TVS-h474/TVS-h674/TVS-h874/TVS-h874X/TVS-h674T/TVS-h874T. TVS-h674 appears there. That is applicability of that release note, not a recrawl of every feature cell, and not a promise every optional NIC still works (LAN-10G1SR cards are called out as h5-only).[1][6]
