Price per TB is the clearest first comparison for capacity storage: divide the current purchase price by rated decimal terabytes. It is not a complete buying decision. Interface, condition, warranty, recording method, workload fit, redundancy, power, and available drive bays can make a higher-priced listing the more defensible purchase.

The HDD table below is live and excludes unavailable listings, invalid capacity, and zero-dollar prices. It ranks 369 current HDD listings by defensible price per TB. NVMe and LTO are summarized separately because their performance, media, and hardware requirements make a raw cross-category ranking misleading.

One change worth flagging in how to read this table: external USB drives now appear in it on merit, and they carry an EXTERNAL badge in the interface column so they are never mistaken for a bare drive. An external is a sealed USB unit whose internal drive the maker may not disclose, while a bare drive publishes its model number, recording technology, workload rating and warranty. If the storage is going into a bay or an array, compare against the best qualifying bare drive rather than assuming the overall first row is suitable. The live external-drive comparison calculates the external-versus-internal relationship from current listings each time it renders.

The same caution applies at the other end of the table. The very cheapest rates here are frequently second-hand enterprise SAS drives at small capacities, and a SAS drive does not plug into an ordinary computer — it needs a host bus adapter and a machine with a slot for one. That is a small obstacle if you have a server and a decisive one if you do not, so read the interface column before reading the rate.

Best $/TB at each capacity

If you need a specific drive size, this table shows the cheapest live $/TB at each HDD capacity tier. For the step-change between capacities, the named sweet spot and frontier premium, and the bay-count arithmetic for when a pricier capacity is still the right buy, see the value-frontier page.

Cheapest archive storage — LTO tape

LTO tape offers the lowest raw $/TB of any storage medium but requires a dedicated tape drive ($2,000-4,000 for LTO-8/LTO-9) making it economical only at 50TB+ scale. Excluded from the main ranking above because it is not a drop-in alternative to an HDD or SSD. See the LTO tape tracker for full cartridge and library pricing.

What is a good price per TB?

The current tracked HDD floor is $14.99/TB, while the live median across this table is $43.75/TB. The new-drive floor is $17.00/TB. The non-new floor is $14.99/TB.

Those live figures describe Market Value, not Historical Value. The Good Price signal separately checks whether the exact listing is favorable against its own stored observations. That distinction matters: the market floor can rise while one exact model is still a good historical buy, or fall while the lowest listing remains expensive for that model.

SSDs are not directly comparable to HDDs on pure $/TB because they serve different latency, IOPS, endurance, and power-per-operation requirements. Use HDDs for capacity tiers and compare the NVMe U.2 tracker when the workload is performance-bound.

New vs refurbished — when to buy each

Non-new inventory can include used, renewed, seller-refurbished, and manufacturer-recertified listings. Those labels do not establish the same provenance, testing, warranty, or support. Compare the exact condition and seller terms, verify SMART data on arrival, run a full test, and use redundancy before trusting the drive.

New stock generally offers a clearer manufacturer support path, but the exact term still depends on the model and seller. For production storage, compare support, replacement inventory, workload requirements, and downtime cost. For secondary capacity tiers, non-new inventory may reduce acquisition cost when health checks, return rights, warranty, and redundancy are adequate.

Methodologysource, cadence and what is includedshow

Prices sourced from Amazon US via the Amazon Creators API on a 2-hour refresh cycle. $/TB is calculated as the current lowest in-stock price divided by the drive's rated capacity. Only in-stock drives are included in this ranking. Refurbished listings are tagged with the REFURB badge.

Frequently asked questions

What is a good price per TB right now?

The current tracked HDD floor is $14.99/TB and the live median is $43.75/TB. Market Value compares relevant current peers, while Historical Value checks the exact drive condition against stored pricing records.

Why are larger drives cheaper per TB?

Hard drive manufacturing costs are largely fixed per unit — the controller, motor, head assembly, and chassis cost roughly the same whether the drive holds 4TB or 20TB. Spreading that fixed cost over more capacity drops the $/TB. Higher-capacity drives also use the latest areal density technology, which improves over time.

Are refurbished drives worth it?

They can be for redundant backup and capacity tiers when the listing condition, seller, return terms, and warranty are explicit. Test the drive on arrival and avoid relying on one non-new drive as the only copy of important data.

Is it cheaper to buy one big drive or several small?

Often, but not always. Compare total acquisition cost and live $/TB, then account for drive bays, power, redundancy, rebuild behavior, and the maximum capacity supported by the enclosure or controller.

How often do these prices update?

Prices on DatacenterDisk refresh about once a day from Amazon US via the Amazon Creators API. The freshness indicator near the top of every page shows the most recent successful refresh.

What's the cheapest way to get 1TB of storage?

The current lowest qualifying HDD listing is HP ST31000640SS at $14.99/TB. Whether it is suitable still depends on interface, condition, warranty, and the system receiving the drive.

Do SSDs cost more per TB than HDDs?

The cheapest tracked NVMe listing currently costs about 8.0 times the price per TB of the HDD market floor. The products serve different latency, IOPS, endurance, and capacity-tier requirements.

Should I buy hard drives now or wait?

Use the live ranking for today's market and the HDD forecast page for observed direction and stated uncertainty. Buy against an actual capacity need, support requirement, and redundancy plan rather than treating a forecast as certain.
