Is it really a deal?
16TB is the clearest example of a tier where a large advertised percentage off still leaves you paying more per terabyte than the next size up. Compare this page against the 18TB and 20TB tables before buying anything here.
For the cheapest row on this page we have recorded a low of CA$674.58 on 2026-10-27, across 7 days of our own checks.
2026 is a shortage year for both hard-drive platters and NAND, and several list prices were raised earlier in the year before being discounted during this event. A percentage off a raised list price is not the same as a low, which is why every row here is compared against what we recorded for that exact item instead.
The cheapest new 16 TB listing today works out at CA$42.16/TB.
Renewed and recertified stock at 16 TB starts at CA$48.52/TB, with the seller rather than the manufacturer behind the warranty.
The cheapest external route to 16 TB is CA$42.16/TB, which you would have to open the enclosure to use as a bare drive.

If one capacity shows what the 2026 shortage did to retail pricing, it is this one. New internal 16TB drives that sat comfortably below six hundred dollars now range into the high seven hundreds, and the Expansion Desktop at 16TB prices above the 18TB and 20TB units in the same family. That inversion is the useful signal on this page: at this tier, checking the capacity above is usually worth more than hunting for a discount. The IronWolf Pro and Exos X18 are the mainstream internal options.
Frequently asked questions
Why does 16TB cost more per terabyte than 18TB?
Retail 16TB stock was repriced during the 2026 squeeze while the newer high-capacity lines kept moving in volume. The result is an inversion where the larger drive is cheaper per terabyte, and at this tier it is the normal case rather than the exception.
Should I just buy an 18TB drive instead?
Usually, yes. Our 18TB page frequently shows a lower cost per terabyte and a lower total price than the 16TB units here. Buy 16TB only when the bay count or the array geometry requires that exact size.
Are the much cheaper 16TB listings elsewhere real?
Some lower figures circulated at other retailers during this event. We only rank and link what we can price on Amazon, so a figure we cannot verify in our own history is not shown and not linked.
Is a 16TB drive a safe single copy of my data?
No drive is, and rebuild time at this capacity is long enough that a second failure during a rebuild is a real risk in a single-parity array. Plan a second copy rather than relying on redundancy alone.
