SATA HDD Average $/TB — Live from DatacenterDisk price history

Daily average price per TB across all tracked SATA enterprise HDDs, daily floor TB, tracked since 2026-08-04. Live data from the DatacenterDisk price tracker — updates about once a day. Window reflects the actual history in our database, not a modeled projection.

Then and now

Every row says where its numbers came from. Reported rows are figures published by others, cited and dated - we did not measure them. Measured rows are our own series, computed from our daily snapshots. Mixing the two without saying which is which is how a page ends up citing itself.

Our tracked hard drives floor, per TB$11.63 (2026-08-04)$14.99 (2026-10-14)Measured by us

Corrected - hard drives floor, per TB: Until 1 October 2026 this series started at $11.33/TB on 23 March. That was a 3TB MDD drive titled "(Renewed)" that Amazon reported as new; under our definition - new means factory-new with the manufacturer's warranty - it was not, and the series now starts at $11.63/TB, a used Seagate Constellation ES.2 3TB SAS listing. We also checked the five listings removed from our averages on 1 October: none of them ever set this floor.

As of 2026-10-14, 43% of scored hard drives carry a GOOD PRICE or GREAT PRICE Historical Value signal. The full distribution is 70 great, 40 good, 90 fair, and 56 high. The remaining 68 read In progress: too few days of records, or a price that has not moved enough across its record to call low or high. These are shared Good Price status counts, not displayed historical prices.

Cheapest HDD per TB

Price per terabyte is the number that compares drives of different sizes fairly. The table ranks every in-stock internal drive by it, new and used together, with the condition on each row. The cheapest new terabyte today is the HP 695842-001 4TB SAS 6G at $17.00/TB; the cheapest used or recertified terabyte is the HP ST31000640SS 1TB SAS at $14.99/TB. The full ranking lives on cheapest per TB.

Cheapest HDD per GB

Price per gigabyte ranks drives in exactly the same order as price per terabyte - it is the same number divided by 1,000 - so the table above answers it too. Where people search per gigabyte they are usually buying a small drive, so here are the drives under 2TB, cheapest per gigabyte first.

Cheapest HDD for NAS

A NAS rebuilds its array when a drive fails, and that is where shingled (SMR) drives do badly. This table lists only new 3.5-inch SATA drives that our catalogue confirms as CMR, from NAS and enterprise lines; drives whose recording technology is unstated are left out, not assumed.

Cheapest HDD for PC

A desktop PC takes a 3.5-inch SATA drive. For a single drive holding games, media or backups, recording technology matters less than in a RAID array, but it is still on every row so you can choose. New drives only, cheapest per terabyte first.

Cheapest HDD for laptop

A laptop that takes a hard drive at all takes a 2.5-inch SATA drive. We hold no 2.5-inch SATA hard drive in stock today; the 14 2.5-inch drives we do track are SAS enterprise drives, which will not connect to a laptop. Most current laptops take an M.2 SSD instead - check your laptop's manual - and for extra storage, an external drive works with any of them.

Cheapest external HDD

External hard drives in stock, cheapest per terabyte first, after our fraud floor and scalper checks. The lowest price overall is WD Elements 1TB Portable HDD at $83.99. Whether an external is cheaper than the same drive bare is on the shucking page, and the full list on external drives.

Premium HDD: enterprise and NAS-class drives in stock

The cheapest drive is not always the right one. Premium lines - enterprise nearline drives and NAS-class drives - carry longer warranties and higher rated workloads, and cost more for it. These are the premium drives in stock now, cheapest per terabyte first; the line each belongs to is on the row.

All prices are current Amazon listings, checked 2026-10-14. Amazon sets the seller and final price at checkout. We price drives against their own history on hard drive deals; this forecast page shows current prices only.

Where hard drives prices are right now

Every figure in this section is read from our own catalogue at the moment you loaded the page, and it is a LEVELS observation rather than a rate. The floor is the single cheapest in-stock listing per terabyte; it can move because one cheap listing appeared or vanished, without the market having done anything. That is why percentage changes on this site come from a matched-model index that compares each listing against its own prior price, and never from comparing one day's floor to another's.

As of 2026-10-14, the floor sits at $14.99/TB and the median across 324 in-stock listings at $43.53/TB. The gap between those two is worth as much as either number on its own: a floor far below the median means the cheap end is one or two listings deep, and a floor close to it means the whole catalogue is priced tightly together.

The two condition tracks price separately and we never merge them. New stock starts at $17.00/TB and the refurbished track at $14.99/TB. A refurbished floor well below the new one is the ordinary state of this market rather than a bargain signal, and scoring one against the other would manufacture a discount that does not exist.

The picks table further down carries the same data at row level, in stock only, so a reader who decides to act can do so without leaving the page. It never shows an out-of-stock row, which is why you will not find an empty price cell anywhere in this cluster.

The trend, on an honest window

Our snapshots for this category begin on 2026-08-04 and run to 2026-10-14, which is 72 days of daily observations. That window is stated because a trend without its window is not checkable, and because 72 days is a real but modest history - long enough to show a level, short enough that a single unusual month shapes it.

Over the most recent 30 days of that series - 2026-09-14 to 2026-10-14 - the daily floor moved from $14.99/TB to $14.99/TB, a change of 0.0%. Read that as what the cheapest listing did, not as what the market did.

The chart is a levels series by design. A levels chart answers 'what does the cheap end cost' and it answers it honestly; it does not answer 'has the market moved', because a single listing entering or leaving changes it. Both questions are legitimate and they need different instruments, so we do not use one chart to imply the other.

The supply side

Hard drive supply has been unusually tight through 2026, and the reasons are structural rather than seasonal. Lead times on enterprise nearline drives have been reported in the region of 52 weeks or more - a buyer placing an order is being quoted delivery a year out, which is a different market from one where stock is simply low.

Western Digital has been reported sold out of nearline capacity, with allocation rather than availability determining who receives drives. When a manufacturer moves to allocation, price stops being set by what buyers will pay and starts being set by who is at the front of the queue, and the retail channel is not at the front of that queue.

The capacity relief that exists is HAMR, the recording technology that lets a platter hold more without a bigger drive. It is shipping, and it raises the ceiling on what a single drive can hold. What it does not do is add manufacturing lines quickly - a new recording technology increases capacity per unit rather than units per month, and the constraint in this market is units.

Those three facts describe the same picture from different angles: demand for high-capacity nearline drives exceeds what the industry can produce, and the mechanism that clears the gap is price and queue position rather than volume.

The outlook, as of 2026-10-14

Our outlook is directional, not a price: the pressure is upward and we see no reversal signal yet.

Directionally, and stated as of the date above: the conditions that pushed drive prices up have not reversed. Lead times measured in quarters do not shorten because retail demand softens, and allocation does not end because a quarter closes. Our own floor has not been behaving like a market in retreat.

That is a statement about direction and about the absence of a reversal signal. It is not a prediction of a price, a percentage or a date, and this page will not print one. Anyone offering you a specific figure for what a terabyte will cost in six months is guessing with more confidence than the available facts support.

The more useful framing for a buyer is that the risk is asymmetric right now. In a market with long lead times and allocation, the downside of waiting is not merely that you pay the same later - it is that the specific capacity you want may not be purchasable at the moment you decide.

What would change this outlook

This is the section that makes the rest of the page worth citing. An outlook with no stated falsifiers cannot be wrong, and a claim that cannot be wrong is not information. Here is exactly what we are watching, and what each of these moving would mean:

Lead times shortening materially in reported industry figures. The 52-week number is the clearest single indicator in this category; if it comes down, the tightness is easing regardless of what any individual price does.

A sustained fall in our own daily floor - not a single cheap listing appearing for a day, but the floor holding lower across weeks. Our chart is a levels series precisely so this is visible.

In-stock breadth recovering. A market where more of the catalogue is buyable at once is a market with slack in it, and we track that count on every category page.

Any of the manufacturers moving off allocation for nearline capacity. That would be reported, and it would change the mechanism that is currently setting price.

We check these monthly and publish the result as a dated check-in whether or not the read changed. An outlook that never revises is not being tested.

What a buyer does with this

If you need capacity now and the price clears your threshold, the case for buying now is stronger in this category than in most, because the constraint is supply rather than sentiment. Waiting in an allocated market risks availability as well as price.

If you are speculating on a fall, the falsifiers above are what you should be watching, and none of them has fired. That is not the same as saying prices will rise - it is saying the reasons they rose are still in place.

Either way, buy on cost per terabyte rather than on sticker price, and check the refurbished track: in this category the decommissioned-fleet supply is deep and it prices independently of the new-drive constraint.

Signals we watch

These are the things that would change the outlook above. They are checked in every monthly edition, and the edition says so whether or not any of them moved.

  • HDDReported nearline lead times shortening from the 52-week-plus figures.
  • HDDAny manufacturer coming off allocation for nearline capacity.
  • Our own matched-model index turning negative across consecutive monthly editions - not one month, a run.
  • Our in-stock breadth recovering for reasons other than our own catalogue growth.

The forecast archive

Every monthly edition, newest first, archived rather than overwritten. Each one opens by stating what the previous edition said and what our data actually did - an archive that never grades itself is a blog, not a record.

Frequently asked questions

What is the cheapest HDD right now?

The lowest-priced internal hard drive in stock today is the HP ST31000640SS 1TB SAS (1TB, used) at $14.99. The cheapest per terabyte is the HP ST31000640SS 1TB SAS at $14.99/TB.

What is the cheapest HDD per TB?

Today, the HP ST31000640SS 1TB SAS (1TB, used or recertified) at $14.99 per terabyte. Price per gigabyte ranks drives in the same order - it is the same figure divided by 1,000.

What is the cheapest HDD for a NAS?

Among new, CMR-confirmed 3.5-inch SATA drives from NAS and enterprise lines, the WD DC HC550 18TB SATA 512MB Enterprise (18TB) at $43.58/TB. We leave out SMR drives and drives whose recording technology is unstated.

What is the cheapest external HDD?

Per terabyte, Seagate Expansion 24TB Portable HDD at $28.33/TB ($679.99). Our external drive pages apply a fraud floor and scalper check before a drive can rank.

Are recertified hard drives the cheapest option?

Often, per terabyte - retired enterprise drives come onto the market in volume. The trade is warranty length and an unseen history. Each row on this page says whether the listing is new or used.

Do you recommend Reddit's cheapest HDD picks?

We do not repeat forum recommendations we cannot verify. What we can offer is the live price of every drive in stock and the specs that matter - condition, interface and recording technology - so you can check any drive a thread suggests against today's price.

Will hard drive prices go down in 2026?

We will not print a number, and you should be sceptical of anyone who does. What we can say directionally, as of the date on this page: none of the conditions that raised prices has reversed. Lead times on enterprise nearline drives have been reported at 52 weeks or more, a major manufacturer has been reported sold out of nearline capacity, and HAMR raises capacity per drive rather than drives per month. The falsifiers section above lists exactly what would change that read.

What is the cheapest hard drive per terabyte right now?

The live floor is at the top of this page and in the picks table, updated about once a day from our own catalogue. It is a levels figure - the single cheapest in-stock listing - so it can move because one listing appeared or vanished rather than because the market moved. That is why percentage changes elsewhere on this site use a matched-model index instead.

Should I buy now or wait?

The honest answer depends on whether you need the capacity. In a market running on allocation and year-long lead times, waiting risks availability as well as price, which is a different risk from an ordinary market. If you are buying anyway, buy on cost per terabyte and consider the refurbished track. If you are purely speculating on a fall, watch the falsifiers rather than the headlines.

Why are hard drives more expensive than they were?

Demand for high-capacity nearline drives has outrun what the industry can produce. When that happens, manufacturers allocate rather than sell freely, and the retail channel sits behind the datacentre buyers in that queue. The reported 52-week-plus lead times and sold-out nearline capacity are the visible symptoms of that.

Does HAMR fix the shortage?

It raises the ceiling on what a single drive holds, which helps a buyer who needs a lot of capacity in few bays. It does not add production lines, and the binding constraint in this market is units per month rather than terabytes per unit. Treat it as capacity relief on a long horizon rather than a supply fix.

How often does this forecast update?

The live figures refresh about once a day with our price data, and the outlook is reviewed monthly - each edition is published as a dated check-in that says what moved and whether the read changed. The date beside every outlook statement on this page is the date it applies to.
