Verdicts: Our tracked low is at or below the lowest price we recorded before today; within 3% is close to it; cut vs list only is below Amazon's reference price but above our low; no history yet means we make no claim. The 90-day line shades the event days. Was prices are Amazon's reference prices.
The HGST Ultrastar 12TB at $329.99 is our tracked low: the lowest we recorded was $330.00 on Oct 5, from every new CMR 12TB NAS drive we track. Of 8 rows, 3 are at or near our low, 0 are cut only against Amazon's list price, 0 cost more than usual, and 5 have no history yet. Both DS223 models are newly tracked; their reference prices are Amazon's list prices, labelled as such. Hard drive prices have risen through 2026 on AI datacenter demand (why hard drives cost more in 2026), so a price that only matches our low is a better outcome than in an ordinary year.

Frequently asked questions
DS223 or DS223j?
The DS223 has twice the memory and handles Synology Photos indexing faster. For simple backup and file sharing, the DS223j is enough and cheaper.
Can the DS223 run Plex?
It can serve media that plays directly. Its ARM chip cannot transcode much, so it is not a Plex server for remote viewers.
What drives suit a DS223?
Two matching CMR NAS drives in SHR or RAID 1. The fill table shows the cheapest pairs today and the usable space you get.
Is the DS223 cheaper on Black Friday?
Entry Synology units usually repeat their sale price on 27 November. If it is listed below Amazon's reference price today and you need it, the risk of buying now is small.
