NAS drive price trends
Monthly median price-per-terabyte for current 8TB+ NAS hard drives (US, new, in stock), from Jul 2024 to the latest month, split into the two tiers people choose between: consumer NAS (WD Red / IronWolf class) and enterprise (Exos / MG / Ultrastar).
Part of the open NAS drive dataset, maintained at nasdisks.com.
The trend
Median $/TB sat flat around $20/TB through 2024 and most of 2025, then roughly doubled to the mid-$40s/TB from late 2025, and has held there since. Both tiers moved together: among new drives, enterprise is not the $/TB bargain it's assumed to be, and both got hit about equally. The usual driver is the AI datacenter buildout pulling high-capacity nearline supply.
Files
monthly-median-per-tb.csv- month, consumer median $/TB, enterprise median $/TB. Computed monthly medians only.
Method
For each month, take each drive's average $/TB across its logged days, then the median of those per-drive values across drives (so a model with more logged days doesn't skew the month). Scope: 8TB and up, US, new in-stock prices, compiled from Amazon price history. CMR/SMR and specs from datasheets.
8TB and up because small drives carry a much higher $/TB (fixed per-drive costs spread over less capacity), and which small SKUs happen to be in stock would swing an all-capacity median for reasons unrelated to prices actually moving.
This folder publishes the computed monthly medians only, not the underlying per-drive price observations.
