After more than ten years of data recovery and storage sales, I first met a customer who came to buy a hard drive. I advised him not to buy it first-not because it was expensive, but because it was expensive.The price of buying now is likely to be higher, and some capacity segments cannot be ordered at all..

The mechanical hard drive market in 2026 is no longer "price increase" can be summarized, it is structural shortage.

To what extent is the shortage: several sets of data

The phrase "capacity sold out" is extremely rare in the history of the hard drive industry. Normal storage markets are cyclical fluctuations-oversupply will reduce prices to inventory, supply exceeds demand will increase prices to expand production. But this time is different:The price has gone up, but the original factory has not expanded its production.

Why Price Increase Does Not Expand Production: Rational Choice of Three Oligarchs

There are only three players left in the global mechanical hard drive market: Seagate, Western Digital and Toshiba. This is a typical oligopoly market, and the behavior logic of the three players is highly consistent:

  1. History teaches us too much.From 2019 to 2023, the storage industry experienced several rounds of fierce price wars. HDD gross profit once fell to single digits or even losses. All three learned the same thing: it is better to sell less than to fight price wars. Expanding production means increasing supply, falling prices, and returning to that nightmare.
  2. The capital return on expansion is not cost-effective.It takes 18-24 months and huge capital expenditure to build a new HDD production line (including heads, disks and precision assembly). Although the data growth in the AI era is fast, the incremental demand is largely eaten up by SSD and cloud, and there is uncertainty in the long-term demand curve of HDD. The board of directors will not approve a possible excess capacity in 3-5 years.
  3. Production control + price increase = profit maximization.Without expansion, production capacity is limited, demand is rigid (data centers must have large capacity cold storage), prices naturally rise, and all three benefit. This is a Nash equilibrium: any one expansion alone will destroy the industry price, so no one moves.
  4. Give priority to large customers.Hyperscale cloud vendors (AWS, Azure, Google, Meta) lock in the vast majority of capacity with 3-5 year LTAs. Channels and SMBs get what's left, with the lowest priority and highest price.

The demand-side push is equally clear:The data generated by AI training is massive, and most of the trained data becomes "warm and cold data"-infrequently accessed but not deleted.(Compliance retention, model training corpus, inference logs). Storage costs for this type of data are sensitive, SSD is too expensive (30TB QLC SSD costs 22.6 times more per TB than HDD), and can only be used on HDD. Morgan Stanley estimates that the 300EB gap mainly comes from data centers.

SSD costs 22.6 times more per TB than HDD: Cold data can only stay on mechanical disks, which is the root cause of HDD demand rigidity

HAMR: Only supply-side variable, but wait

Seagate's HAMR (Thermally Assisted Magnetic Recording) technology is key to increasing single-disk capacity-using lasers to instantaneously heat media locally to make high-coercivity materials writable, thus achieving higher recording densities. Seagate Mozaic 3+ series has been mass-produced at 32TB, and the roadmap points to 40TB+.

However, HAMR cannot solve the shortage in the short term for three reasons:

Western Digital's ePMR/OptiNAND route and Toshiba's FC-MAMR take a gradual upgrade to a capacity of 26-30TB, also giving priority to large customers.Conclusion: In 2026 - 2027, the supply to SMEs and NAS users will not improve significantly.

Price changes weekly, please confirm by phone before purchasing. ACCPC does wholesale hard drive (Seagate, Western Digital, Toshiba, Armor, NAS disk/enterprise disk/CCTV drive/desktop disk), enterprise bulk purchase can lock the price for 30 days, including SMART detection and burn-in test delivery (to avoid bad). It also provides data recovery services-hard drive price increases in the years, the existing disk data to save back is often more cost-effective than buying a new disk. Telephone 020-39029800.
