12TB is a mainstream NAS capacity that is reliably CMR across every enterprise and NAS-branded family, so the usual recording-technology trap does not apply. Recertified supply comes from datacenter refreshes that are now well underway, and both conditions are deep enough to price honestly.
Both measurements agree at 12TB: recertified stock undercuts new on the cheapest listing and on a like-for-like model comparison. That agreement is what makes the saving trustworthy - when only the shelf figure is positive, the gap is usually telling you that the cheapest new drive is a different class of product rather than that recertified is a bargain. Here it is not. The saving is real, and the thing you trade for it is the manufacturer warranty and the certainty about how the drive spent its first few years.
Both tables are the same live catalogue the spread above is computed from, so the figures and the listings cannot disagree. Prices are the current price only; we do not show what any of these drives cost in the past.
"Recertified" is not one thing. Manufacturer-recertified stock has been returned to Seagate or WD, tested against factory criteria and re-warrantied. Reseller-refurbished stock is usually a datacenter pull, tested and graded by a specialist and covered by that specialist's own warranty. Bare "used" on an open marketplace is unknown provenance and carries no independent testing at all. Those three tiers carry genuinely different risk, and the recertified drives guide sets out how to tell them apart and which sellers sit where.
The prices on this page cannot make that distinction, and we would rather say so than imply a precision the data does not have. Our catalogue records two conditions, new and used, so every non-new listing above sits in one bucket regardless of which tier it belongs to. Read the listing itself for the tier before you buy, particularly at capacities where the spread is narrow enough that the warranty is worth more than the saving.
A recertified drive is worth buying on the condition that you check it, and the check takes minutes. Read the SMART attributes before the drive holds anything you care about: power-on hours tell you its age, reallocated sectors tell you what has already failed and been remapped, and current pending and offline uncorrectable counts tell you what is failing now. Non-zero pending or uncorrectable counts are grounds to return it. A modest reallocated count on a drive with tens of thousands of hours is normal and not a reason to reject it. The SMART attribute guide explains what each value means and where the thresholds sit; run a full long self-test before the drive joins an array, and deploy at this capacity with dual parity rather than single.
This is where new and recertified genuinely differ, and it is the part a cost-per-terabyte table cannot show. New drives at 12TB carry a manufacturer warranty, typically three to five years on enterprise lines, honoured by Seagate or WD directly. Manufacturer-recertified stock is usually re-warrantied for a shorter term but still by the manufacturer. Reseller-refurbished stock is covered by the reseller, which means the cover is only as good as that business remaining solvent and reachable. Bare used stock has no cover at all beyond the marketplace's own returns window.
Price that difference deliberately rather than ignoring it. At 12TB the current spread is inside fifteen percent, which is comfortably less than a warranty is worth on a drive you intend to run continuously. The refurbished warranty guide covers what each tier actually provides and how claims tend to go.
Two figures, because there are two questions. The shelf spread compares the cheapest in-stock recertified listing at 12TB against the cheapest new one - that is what you pay if you buy the cheapest thing available in each condition today. The like-for-like discount compares each model against itself, new against recertified, and averages the result across every model stocked in both conditions at once.
They disagree at several capacities, and the reason matters. The cheapest new drive and the cheapest recertified drive are frequently different products from different segments - a consumer SATA drive against a retired enterprise SAS unit. Subtracting them measures the product mix at that capacity as much as it measures the condition. This is the same correction we apply to price movement across the site, where comparing medians between dates once reported a fifty-three percent move that was entirely caused by adding drives to the catalogue. Any percentage on this page that describes a difference is matched; any figure that describes a level is a level and is labelled as one.
The verdict is computed per capacity and it is not the same everywhere - recertified wins decisively at some capacities and loses at others, depending on how much secondary stock has reached the market and what the new side happens to consist of.

Two answers, because there are two questions. The cheapest recertified 12TB listing we track is $26.58 per terabyte against $28.33 for the cheapest new one, a +6.2% difference. But those are different drives. Comparing each model against itself - the same drive new and recertified - gives +28.4% across 8 models, and that is the figure that tells you what the condition is worth on the drive you actually want.
Buy recertified at 12TB. The recertified stock at 12TB undercuts new on both measurements, so the saving is real rather than a product of what happens to be in stock. Verify the drive on arrival regardless - the discount assumes you check what you received.
Our price data records two conditions, new and used, and everything that is not new lands in the used bucket - manufacturer-recertified stock and graded datacenter pulls both. We do not claim to distinguish the tiers in the figures on this page, because the source data does not. The distinction between manufacturer-recertified, reseller-refurbished and bare used matters a great deal when you buy, and it is set out in full on the recertified drives guide.
20 recertified and 18 new in-stock listings at 12TB at the last price refresh. The like-for-like figure is narrower still: it uses only models stocked in both conditions at the same time, currently 8. We publish the count next to the percentage everywhere because a discount averaged over three models and one averaged over sixteen are not the same claim.
Read SMART before the drive goes anywhere near live data: power-on hours, reallocated sectors, current pending sectors and offline uncorrectable. Reject anything with non-zero pending or uncorrectable counts. A modest reallocated count on a high-hour enterprise drive is normal; pending sectors are not. Then run a full long self-test before adding it to an array. The SMART attribute guide walks through what each value means.
No, and that is a real gap in any price-per-terabyte comparison. A new drive typically carries a manufacturer warranty of three to five years; recertified stock carries whatever the reseller offers, which is often shorter and always dependent on that reseller still trading. When the spread is narrow - and at several capacities in this cluster it is - the warranty difference is worth more than the price difference.
