Is it really a deal?
Of the 11 Amazon.ca listings we checked here, 4 are at or under the lowest price we recorded before the event and 1 is within 3% of it. The strongest is QNAP TS-433-4G-US 4-Bay NAS at CA$629.08, against our pre-event low of CA$629.10 on Sep 29, 2026. 2 more show a cut only against Amazon's list price, which is not a price anyone usually pays. 1 is sold by Amazon US through Amazon.ca, which means shipping and returns cross the border. 3 are too new to our tracker to judge, and we say so rather than guess.
What it costs filled with drives
NAS price plus the cheapest new CMR NAS hard drives that fit it, all bays filled. Usable space from the same RAID maths as our RAID calculator; running cost from the NAS power cost calculator at Ontario’s weighted rate.

Questions about 4-Bay NAS deals
RAID 5 or RAID 6 on a 4-bay NAS?
RAID 5 keeps three drives of capacity and survives one failure; RAID 6 keeps two and survives two. With 16TB-plus drives, long rebuilds make the second parity drive worth weighing.
Which 4-bay NAS here has 10GbE?
The DXP4800 Plus pairs 10GbE with 2.5GbE, and the DXP4800 GT lists two 10GbE ports on its Amazon.ca listing. The others need an add-in card or stop at 2.5GbE.
How much do four drives add to the price?
Four new CMR NAS drives typically cost as much as the NAS or more in Canada right now. The fill-cost table adds the cheapest matching set and the after-tax total.
Is the DH4300 Plus a real 4-bay NAS?
Yes, with four bays and an 8-core ARM processor. It is built for storage and backup rather than Plex transcoding or virtual machines.
