TS-873A-8G: specifications and dated store comparison →An eight-bay Ryzen platform with QuTS hero and PCIe growth, but demanding ZFS or 10GbE plans need more than the factory 8GB.
Exact US MPN TS-873A-8G-US; official hardware table TS-873A-8G; 8 GB SODIMM DDR4; 8 x 3.5-inch SATA 6Gb/s, 3Gb/s.
Based on the current QNAP specification tables and 1 applicable original review. We have not tested this NAS ourselves. The hardware-page software tables are QTS 5.2.9 / QuTS hero h5.2.9 (version-bound). TS-873A is listed in Applicable Models on the separate QuTS hero h6.0.2.3591 notes dated 2026-08-24; that listing is not the h5.2.9 feature table. See the review evidence ↓
Is the TS-873A-8G right for you?
Expandable eight-bay business storage
An eight-bay Ryzen platform with QuTS hero and PCIe growth, but demanding ZFS or 10GbE plans need more than the factory 8GB.[1]
Large ZFS pools after planned RAM upgrades
Plan the array and client path around 10GbE: Optional via a PCIe adapter; 2.5GbE: 2 (2.5G/1G/100M).[4]
You want 10GbE ready without upgrades
The exact factory configuration and platform limits do not make this the safest default for that need: you want 10gbe ready without upgrades.[1]

Hardware, storage and network planning
Plan storage and networking together
Storage: 8 x 3.5-inch SATA 6Gb/s, 3Gb/s. Connectivity: 10GbE: Optional via a PCIe adapter; 2.5GbE: 2 (2.5G/1G/100M). Advertised port speed is not a guarantee for one file transfer; drive count, RAID, protocol, client and switch can each become the limit.[1]
Read measured results with their setup
ServeTheHome measured the factory 8GB SODIMM path: eight 8TB IronWolf drives, QuTS hero RAID-6/RAIDZ2, 2.5GbE SMB 240/235 MB/s. IT Pro’s 9.2/7.8 Gbit/s figures used 32GB RAM, a Broadcom 10GbE card, mirrored 960GB Micron SSDs for the system pool, and three 14TB IronWolf Pro HDDs — related upgrade-path only.[5][4][1]

ServeTheHome 8GB / 8x8TB RAIDZ2 on 2.5GbE
STH’s unit had a single 8GB Kingston SODIMM. On QuTS hero with eight 8TB IronWolf drives in RAID-6/RAIDZ2, the SMB chart is 240/235 MB/s read/write over 2.5GbE. A video-project copy chart is in seconds (~405 read / ~630 write) without a file-size label. Idle-empty power 26W and max 58W at 120V; 1m noise idle 25 dBA / moderate disk 31 dBA. That is factory-memory throughput on 2.5GbE, not a 10GbE card test.
