Eight-bay desktop NAS for high-capacity storage

The TS-873A-8G-US is a diskless desktop NAS with eight SATA drive bays supporting up to 176TB of raw capacity. It runs QTS 4.5.2 on an AMD Ryzen V1500B processor at 2.20 GHz with 8GB DDR4 installed, expandable to 64GB via two SODIMM slots. Two 2.5 GbE ports and multiple USB 3.2 connections provide flexible network and peripheral attachment.

Suited for teams needing RAID flexibility

This unit fits organisations that want to configure their own mix of 3.5" HDDs, 2.5" HDDs or 2.5" SSDs across RAID 0, 1, 5, 6, 10, 50, 60 or JBOD. The two M.2 2280 PCIe Gen3 x1 slots and two PCIe 3.0 x4 slots allow cache or expansion cards. Buyers who require 10 GbE networking out of the box or a smaller bay count should consider other models.

Eight SATA bays define the storage ceiling

The eight-bay chassis sets the hard limit of 176TB maximum capacity and determines which RAID levels are practical. If your dataset will exceed this ceiling or you need more than eight drives, this chassis cannot accommodate the requirement.

Perguntas sobre este artigo

Will the TS-873A-8G-US work with my existing 3.5" SATA hard drives?

Yes, each of the eight bays accepts 3.5" SATA HDDs as well as 2.5" SATA HDDs or SSDs, so your current drives can be installed directly.

How can I confirm the two 2.5 GbE ports are running at full speed after setup?

In QTS 4.5.2 open Control Panel → Network & File Services → Network → Interface; each RJ-45 port should show a 2.5 Gbps link speed when connected to a 2.5 GbE switch.

What comes in the box and what must I purchase separately?

The unit ships diskless with a 250 W power supply, so you must buy 3.5" or 2.5" SATA drives and optional DDR4 SODIMM modules if you want more than the installed 8 GB.
