2-Bay NAS Deals – Prime Big Deal Days 2026
Two bays means one mirrored pair: every file is written twice, so usable space equals one drive. That makes the drive choice matter more than the enclosure, and with large drives scarce in 2026, the total for enclosure plus two drives is the figure to compare. The fill table does that sum with today's prices.

Nothing here is at a tracked low, because we hold no price history for these listings before this week. The lowest-ranked row is the Synology DS223j at $178.49 against Amazon's own reference price of $209.99, with no verdict claimed.
Worth checking out today
Few 2-Bay NAS listings have enough price history with us to call a tracked low yet, so these are the standouts on Amazon.com today: Prime-exclusive offers first, then the deepest cuts against Amazon's own reference price. Amazon's reference is its figure, not our price record.

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.
We have no price record from before this week for the listings on this page, so we make no claim beyond showing Amazon's own reference price. Of 9 rows, 0 are at or near our low, 0 are cut only against Amazon's list price, 0 cost more than usual, and 9 have no history yet. For a mirror, the drive pair usually costs more than the enclosure, so check the fill table before choosing on enclosure price alone. 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.
Fill cost with today's hard drive prices
Enclosure plus the cheapest new CMR NAS drives in stock today, and the same capacity bought as shucked externals. Usable space comes from our RAID calculator (after about 9% formatting overhead).

Frequently asked questions
How much usable space does a 2-bay NAS give?
In a RAID 1 or SHR mirror, usable space is one drive's capacity minus about 9% for formatting. Two 12TB drives give roughly 10.9TB usable, which the fill table works out per capacity.
Is a 2-bay NAS enough for Plex?
For a household library, yes, if the CPU has Quick Sync. The DXP2800, DS225+ and TS-264 do; the DH2300, DS223, DS223j and TS-233 do not and should direct-play only.
Can I add drives later to a 2-bay NAS?
Not beyond two bays. You can replace both drives with larger ones one at a time and expand the mirror, which is why buying the largest drives you can afford now is usually cheaper.
Do I need Prime for 2-bay NAS prices?
Only for rows marked Prime deal. Everything else is the normal Amazon.com price.
