Right now, a good SATA HDD price is under $25/TB. The market's best available is $10.63/TB on refurbished enterprise stock. Anything approaching that floor is an excellent buy; anything above $37/TB means you are paying a shortage premium.
Take the price you are looking at, divide by the drive's capacity in TB, and find your number in the column for that drive type. The thresholds below are computed live from the current in-stock market — the "Excellent" band sits near the live floor, "Overpriced" sits above the 75th percentile of what is actually selling.
| Verdict | SATA HDD | SAS HDD | NVMe SSD |
|---|---|---|---|
| Excellent | ≤ $12/TB | ≤ $12/TB | ≤ $28/TB |
| Good | ≤ $25/TB | ≤ $30/TB | ≤ $195/TB |
| Fair | ≤ $37/TB | ≤ $42/TB | ≤ $259/TB |
| Overpriced | > $37/TB | > $42/TB | > $259/TB |
Thresholds recompute every 2 hours from live in-stock inventory. Compare within a category only — never judge an NVMe price against an HDD benchmark.
For a decade, the community rules of thumb were simple and stable: under $15/TB was a good price, under $10/TB was a deal worth acting on, and under $5/TB meant buy immediately. Those numbers held because HDD areal density improved on a predictable curve and supply comfortably met demand. They are now obsolete.
The 2026 reality, per current market commentary: under $20/TB is the new "buy it now," $20-30/TB is the new "reasonable," and over $30/TB means you are being fleeced. The entire curve shifted up because the shortage is demand-driven and structural — hyperscalers buying out nearline supply, tariffs on imported hardware, and a NAND shortage that dragged SSD pricing up and pulled HDD demand along with it.
But here is the nuance the consumer commentary misses: our live data shows the real enterprise floor is lower than the mainstream advice suggests. Refurbished enterprise SATA is trading at $10.63/TB right now. That gap between the popular "buy under $20/TB" rule and the actual enterprise floor is exactly the value of tracking real prices instead of memorizing a number that goes stale in a month.

Hard drive manufacturing cost is largely fixed per unit. The controller board, spindle motor, actuator, head assembly, and enclosure cost roughly the same whether the drive holds 4TB or 24TB — capacity comes from adding platters and packing bits denser, which is cheap relative to the fixed hardware. Spreading that fixed cost over more terabytes is why a 20TB drive almost always beats a 4TB drive on $/TB, and why the sweet spot keeps climbing as density improves. In 2026 the best $/TB lives in the high-capacity nearline tier. See the live floor at each size on the cheapest per TB rankings and per-capacity pages like 20TB HDDs.
The sub-floor deals live in refurbished enterprise stock. Datacenter pulls — Seagate Exos and WD Ultrastar removed from decommissioned hyperscale arrays, tested and regraded — routinely undercut new pricing by 20 to 40 percent on $/TB.

A refurbished enterprise drive at 20,000 power-on hours is built for 24/7 duty and is often more reliable than a new consumer drive — deploy it in RAID 6 with a hot spare and SMART-verify on arrival. Browse refurbished enterprise stock via MDD listings.
The reason a fixed "good price" number is useless in 2026 is that the benchmark is a moving target. AI infrastructure demand keeps pulling nearline HDD supply toward hyperscalers, Western Digital is sold out for the calendar year, tariffs add cost across the import chain, and the NAND shortage inflating SSDs pulls adjacent demand onto HDDs. Each of these pushes the floor around week to week. The only way to know whether a price is good today is to check it against today's live market — which is what this page does. For the full driver breakdown, read hard drive prices are up 50% in 2026.
For enterprise SATA hard drives, a good price in 2026 is anything at or below the current median of about $25/TB, and a genuinely strong deal is anything approaching the live floor of $10.63/TB. The pre-2025 rule of "under $15/TB is good" no longer holds — the shortage pushed the whole curve up. Judge a price against today's live benchmark, not last year's, because the number moves every week.
In the 2026 market, under $20/TB has become the new "buy it now" threshold for enterprise HDDs, $20-30/TB is merely reasonable, and above $30/TB you are overpaying. That is a big shift from 2024, when $20/TB would have looked expensive. Refurbished enterprise drives still beat that comfortably — the live floor on refurb enterprise SATA is often well under $12/TB.
Three compounding forces: AI infrastructure demand pulled hyperscalers to buy out nearline HDD supply (WD is sold out for 2026), tariffs added cost across the storage supply chain, and the NAND/DRAM shortage inflated SSD pricing and indirectly pressured HDDs. None of these is a short-term factory problem, so the elevated $/TB is structural, not a temporary blip.
The lowest live price per TB across everything we track is $5.44/TB in the LTO Tape category. That figure updates every two hours; the live benchmark table on this page always shows the current floor for each category.
No. HDD and SSD serve different roles and their $/TB figures are not interchangeable. Enterprise NVMe runs many times the cost per TB of HDD but delivers vastly higher IOPS and lower latency. Compare within a category — SATA HDD against SATA HDD, NVMe against NVMe — and choose the category by workload, then optimize $/TB inside it.
It is a fair comparison of cost, but not of risk profile. Refurbished enterprise drives deliver the lowest $/TB by a wide margin, and a tested datacenter pull is often more reliable than a new consumer drive. But they carry accumulated wear and shorter warranties, so the honest comparison is refurb-in-RAID-6 versus new-with-full-warranty. For redundant arrays, refurb wins on $/TB; for single-drive deployments, buy new.
