Storage Squeeze 2026: Why Both SSDs and Hard Drives Got Expensive
For twenty years, buying computer storage followed one rule: whichever type cost more was about to get cheaper, as flash memory closed in on the hard drive. In 2025 and 2026, that rule broke. Both solid-state drives and hard drives got scarce and expensive in the same twelve months - the first time that has ever happened together.
This video traces why. It starts with Toshiba's 2015 roadmap, which staged a prediction that flash would match hard-drive prices by around 2025 - and with Jim Handy, the storage analyst who bet the opposite way and was closer to right: multiple 2026 market surveys still put the cheapest hard drives at roughly a fifth of the cheapest flash's cost per gigabyte.
Then it follows the AI boom that broke the schedule instead. Training AI models pulled memory-chip factory capacity toward high-bandwidth memory (HBM) - which Micron says needs about three times the wafer area of ordinary DRAM for the same capacity - starving the rest of the memory market, NAND flash included. Phison's CEO reported one widely used NAND chip's contract price more than doubling between July and November 2025, and TrendForce logged further quarter-on-quarter jumps into 2026.
At the same time, Western Digital's CEO Irving Tan told investors the company is 'pretty much sold out' for 2026, with hyperscale buyers including Amazon, Google, Microsoft, Meta and OpenAI absorbing most of it years in advance. Seagate's nearline drives - the mass-capacity drives built for data centres - reached 87% of its hard-drive revenue. The reason: AI's cold, rarely read training data is too large to justify flash's five- to six-times cost premium, so hyperscalers lock in cheap hard drives instead.
Both companies' next capacity jump depends on HAMR (heat-assisted magnetic recording), with Seagate's first drives already in production and Western Digital's not reaching full volume until 2027. Independent analyst Glenn Klockwood argues the NAND and DRAM/HBM shortages share a cause - years of pre-AI underinvestment - but not a mechanism, since the two chip families are built on different factory equipment.
Goldman Sachs estimates 2026 global supply shortfalls of about 5% for DRAM, 4% for NAND and 5% for HBM, with relief not expected before 2027 at the earliest. The verdict: flash never finished killing the hard drive, and cheap storage never arrived on schedule - AI demand now sets the price of both.
