RAM was the first line on the server bill to move this year. Storage is the second. A 30TB TLC enterprise SSD that sold for about $3,460 a year ago was quoted at $22,600 in August 2026 — a rise of roughly 552%, tracked by VDURA's Flash Volatility Index and reported by Tom's Hardware on August 21, 2026. That is not a spot-market blip on consumer drives. It is the class of disk that sits under the virtual machine you rent, and its cost is now working its way toward the monthly quote.
Why storage is short, not just memory
The memory crunch and the storage crunch have the same root cause and two different shapes. AI build-out consumes DRAM and high-bandwidth memory first, and that side has been in the headlines for months. But the same demand has now reached disk. Enterprise SSD demand pulled the top five NAND vendors — Samsung, SK hynix, Micron, Kioxia and SanDisk — to a combined $37.59 billion in enterprise SSD revenue in the second quarter of 2026, a 103.6% jump quarter-on-quarter, per TrendForce on September 1, 2026. Revenue roughly doubling in a single quarter is what a supply shortage looks like from the sell side: the same drives, far more money.
Hard drives are no relief valve. Seagate and Western Digital have told investors that nearline HDD output — the high-capacity drives data centres buy by the pallet — is sold out through 2027. A 30TB nearline HDD that cost about $495 in the third quarter of 2025 was quoted near $1,216 in August 2026, up roughly 150%. When the cheap tier is booked out two years ahead, buyers who need capacity now are pushed toward flash, which tightens flash further.
What the numbers actually say
Per terabyte, the gap is stark. At August 2026 quotes, enterprise SSD ran about $753 per terabyte against roughly $40.53 for HDD — about 18.6 times more expensive for the same stored terabyte. NAND contract prices climbed in steps through the year: 55–60% in the first quarter, 70–75% in the second, and 10–15% in the third, according to the same VDURA index; TrendForce independently put third-quarter NAND contract increases at 10–15% quarter-on-quarter. Enterprise SSD contract prices alone rose about 80% in the first quarter of 2026.
The one piece of good news is direction of change, not level. The quarterly rate of NAND increases is slowing — 10–15% is far below the second quarter's 70–75%. Consumer and spot flash may cool first. But the enterprise SSD and nearline HDD that hosting providers actually purchase are a separate, still-tight market, and the level is already high. Slower increases on top of a doubled base still means next year's drives cost more than this year's.
What it costs on a real plan
Provider list prices for add-on storage have not moved in step — yet — and that lag is the thing to watch. DigitalOcean still charges $0.10 per GiB per month for block storage, so a 1 TiB volume is $102.40 a month, exactly as it was before the squeeze. That price was set when the underlying flash cost a fraction of today's. A provider filling that volume with current enterprise SSD is now paying on the order of $750 per usable terabyte for the hardware, against a couple of hundred dollars a year ago. Something has to give: either add-on and plan storage prices rise to meet the component cost, or the included disk on entry plans stops growing and starts shrinking. Both are already visible across the market, and both land on the buyer as fewer gigabytes for the same money. If you are budgeting a database server or a storage-heavy workload, price the disk as a line that will move, not a fixed background cost — the catalog lets you compare what each plan actually includes.
What to do if you are choosing a server now
Three moves make sense while the market is tight. First, separate hot storage from cold: keep the fast NVMe you truly need for the database or application, and push backups, archives and media to cheaper object storage rather than paying flash prices for data you rarely read. Second, lock capacity you know you will need rather than assuming you can top up cheaply later — with nearline HDD sold out through 2027, "add more disk next quarter" is a weaker plan than it was. Third, right-size instead of over-provisioning; at $753 a terabyte on the flash side, idle headroom is now real money. For a database workload specifically, our VPS for a database guidance walks through sizing disk to the working set rather than to a round number.
The figures here come from VDURA's Flash Volatility Index as reported by Tom's Hardware on August 21, 2026, TrendForce's September 1, 2026 enterprise SSD revenue release, and Seagate and Western Digital statements to investors on nearline HDD supply; the block-storage price is DigitalOcean's published rate.
