# Hard-drive unit prices

Backing data for `hdd_prices.png`. Prices are for a complete drive — spindle motor, platters, actuator arm, heads, bearings, enclosure, drive electronics — not $/GB. Capacity is listed only to identify the quoted product; it is not used in the plotted value.

The historical series is a low-advertised retail / street-price series assembled from old ads and web archives. Read it as "what did a cheap complete HDD cost as a physical mechanism?", not as an industry average selling price.

## Inflation methodology

All real prices in **2026 USD** using BLS CPI-U (All Items, U.S. City Average). Annual-average CPI where available; 2026 anchored at CPI ~325 (early-2026 BLS series still partial as of April 26, 2026).

CPI-U multipliers to 2026:

- 1980 — 3.94× (CPI 82.4)
- 1985 — 3.02× (CPI 107.6)
- 1995 — 2.13× (CPI 152.4)
- 2000 — 1.89× (CPI 172.2)
- 2005 — 1.66× (CPI 195.3)
- 2009 — 1.52× (CPI 214.5)
- 2012 — 1.42× (CPI 229.6)
- 2016 — 1.35× (CPI 240.0)
- 2019 — 1.27× (CPI 255.7)
- 2023 — 1.07× (CPI 304.7)
- 2026 — 1.00× (CPI ~325)

## Interpretation

The unit-price picture is much less dramatic than the storage-density picture:

- The complete-drive mechanism fell from **~$16,500 (2026 USD)** in 1980 to the low hundreds by the early 2000s.
- Since the early 2000s, the cheap complete-drive floor has lived around **$50–200 real**, depending on sale timing, capacity class, and whether the quote is bare internal, external, refurbished, or enterprise.

That is the relevant distinction for the "mechanical movement" analogy. HDDs got far cheaper *per byte* because the same basic electromechanical package stored vastly more data — but the price of the physical precision assembly itself did not fall by seven or eight orders of magnitude.

## Industry events and caveats

### HDD industry consolidation

- HDD production is concentrated in three suppliers: Seagate, Western Digital, and Toshiba.
- Implication: modern price movement reflects capacity allocation, cloud/datacenter demand, product mix, and supplier discipline — not only manufacturing yield.

## Plot construction

- Y axis: **2026 USD per complete drive**, on a log scale.
- Dotted segments interpolate between discrete sourced price anchors.
- Capacity is shown only to identify the quoted drive — deliberately not normalized away, because the intended proxy is the complete mechanical assembly rather than storage.
- 2026 rows should be refreshed before publication; the HDD market was moving quickly in early 2026.
