Is it really a deal?
8TB has the deepest price history of any capacity we track, which makes its verdicts the most reliable on the site. A real low at this tier means something, because there are months of comparison behind it.
For the cheapest row on this page we have recorded a low of CA$399.99 on 2026-10-31, across 15 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 8 TB listing today works out at CA$46.25/TB.
Renewed and recertified stock at 8 TB starts at CA$39.88/TB, with the seller rather than the manufacturer behind the warranty.
The cheapest external route to 8 TB is CA$46.25/TB, which you would have to open the enclosure to use as a bare drive.

8TB is where bulk storage starts being worth the shelf space, and it is an unusual tier in 2026 because it is old enough to be built on mature platters and therefore less exposed to the shortage than 16TB and above. Both internal 3.5-inch drives and desktop externals live here, and the external is frequently the cheaper route to the same platters. The tier's weakness is that 12TB and larger often beat it on cost per terabyte outright, so treat 8TB as a size decision rather than a value one.
Frequently asked questions
Is 8TB still good value in 2026?
It is the least shortage-affected tier, but 12TB and above usually still beat it on cost per terabyte. Buy 8TB because it is the capacity you want, not because you expect it to be the cheapest per terabyte on the page.
Should I buy an 8TB internal or an 8TB external?
The external is often cheaper for the same platters, and desktop 3.5-inch units can usually be opened for the bare drive. If the drive is going into a NAS, read our shuckable page first, because what is inside varies.
Is an 8TB drive likely to be SMR?
Some consumer 8TB models are, and shingled recording slows sustained writes badly in a RAID rebuild. Our WD Red page flags SMR explicitly; for a NAS at this size, confirm the model is CMR before buying.
What did 8TB drives do during the event?
Less than the larger sizes. The 2026 cuts concentrated on 18TB to 24TB externals, so at 8TB more rows show a markdown against a list price than a genuine low, and the verdict column separates the two.
