Is it really a deal?

Clearing twenty-five per terabyte is a threshold, not a verdict. A drive can be under the line and still be above its own tracked low, which is why both columns are shown.

For the cheapest row on this page we have recorded a low of CA$35.80 on 2026-10-06, across 16 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.

What the verdicts mean

Real low
At or below the lowest price we have recorded for this item.
Near its low
Within three percent of the lowest price we have recorded.
List-price cut
Cut against Amazon's own reference price, but still above the lowest price we have recorded.
Not a deal
Above our 30-day median for this item.
No history yet
We have fewer than seven days of our own price checks for this item.

A single threshold, applied live: every hard drive we price at or below twenty-five per terabyte right now. The list is mostly recertified enterprise stock and large desktop externals, which is the honest shape of cheap bulk storage in 2026, so the condition column is the first thing to read rather than the last. Membership changes with every price check, and a drive that qualifies today may not tomorrow. Nothing here is ranked across conditions: new, renewed and used each get their own table and their own ordering.

Frequently asked questions

What kinds of drives clear this threshold?

Mostly recertified enterprise units and large desktop externals. New internal retail drives rarely qualify in 2026, which is itself the clearest summary of what the shortage did to pricing.

Does the list change during the day?

Yes. Membership is recalculated at every price check, and during the event that was three times a day, so a drive at twenty-five and a bit drops off and a drive at twenty-four and a bit appears.

Is under twenty-five per terabyte a good price in 2026?

It is the practical floor for anything with a warranty attached. Tape goes far lower and needs a drive costing thousands, so for disk storage this threshold is roughly where the market bottoms out.

Why are conditions not ranked together here?

Because a recertified drive at twenty per terabyte and a new drive at twenty-four are not competing offers. Each condition gets its own table and its own ordering so the comparison stays honest.
