TVS-h874-i5-32G: specifications and dated store comparison →Eight-bay i5-12400 / 32 GB ZFS NAS that is fast on 10GbE in independent tests, not on the stock 2.5GbE ports alone.
Exact US MPN TVS-h874-i5-32G-US; official hardware table TVS-h874-i5-32G; 32 GB SODIMM DDR4; 8 x 3.5-inch SATA 6Gb/s, 3Gb/s.
Based on the official TVS-h874 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 4 applicable original review record(s). We have not tested this NAS. Related other-SKU tests stay labelled related. See the review evidence ↓
Eight SATA bays, i5-12400, 32 GB and a documented 10GbE RAID path in StorageReview/IT Pro.[1]
Stock networking is dual 2.5GbE; Club386 saturated that with six IronWolf HDDs.[1][7]
No ECC in the official SODIMM DDR4 table; 10GbE is optional, not built-in (unlike some i9-X specials).[1]
Follow any specification for its full conditions and sources.
Living with it
This page covers TVS-h874-i5-32G-US, mapped to official table TVS-h874-i5-32G. CPU: Intel® Core™ i5-12400 6-core/12-thread Processor, burst up to 4.4 GHz. Factory memory: 32 GB SODIMM DDR4. Drive bays: 8 x 3.5-inch SATA 6Gb/s, 3Gb/s. US store SKU TVS-h874-i5-32G-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-h874 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][8]
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.

Eight 18TB RAID6 drives delivered approximately 242/231 MB/s read/write in the chart. Typical-use power ranged from 54–60W to just above 90W; normal-use noise was 36 dBA against a 34 dBA room floor.

Tested: Evaluation TVS-h874-i5, factory 32 GB (2×16 GB Transcend DDR4-3200); six 8TB IronWolf HDDs + one 500GB WD Red SN700 M.2. Client PC had an Asus XG-C100C 10GBase-T card; the NAS itself was not shown with an add-in 10GbE NIC in the opened extract. Client processor: Ryzen 9 5950X.
Applies to: Exact TVS-h874-i5-32G CPU/RAM. Reviewer's own Windows copy saturated factory 2.5GbE with six HDDs. 25GbE/~2,950 MB/s figures in the article are QNAP in-house charts, not Club386 meters. Six drives, not eight. Not transferable to i7/i9.

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]
