## Methodology
- **CMR vs SMR** is classified from manufacturer datasheets and model-number decoding. SMR drives shingle their tracks, which cripples random-write and RAID-rebuild performance, so the distinction is the single most important spec for a NAS - and manufacturers do not always advertise it. The `confidence` column in `cmr-reference-2026-06-16.csv` flags how certain each call is.

The `confidence` column in `cmr-reference-2026-06-17.csv` flags how certain each call is.
- **Noise and helium** are read from manufacturer datasheets (idle/seek A-weighted sound power; helium-seal designation) and are licensed CC BY 4.0 alongside the other specs.
- **Failure rates** are computed from Backblaze's raw 2025 quarterly Drive Stats, aggregated to a full-year annualized rate and validated against Backblaze's own published fleet figure (~1.36% for 2025). Only the catalog models that exactly match a Backblaze-tracked model carry an `afr_pct`; the rest are left null rather than guessed.
- **`series-reliability-2026-06-16.csv`** gives manufacturer-rated context (warranty years, workload TB/year, MTBF) for lines Backblaze doesn't run, so you have *something* to reason about beyond a blank cell.

## Updates
This repo is a point-in-time snapshot; the date in each filename is its export date and it can fall behind. For current data use [nasdisks.com/data/](https://www.nasdisks.com/data/) or the endpoints above, which always reflect the latest catalogue and Backblaze figures.
## Changelog
- **2026-06-17** - Added per-drive noise (idle / seek A-weighted sound power, dB) and helium-fill fields. Corrected WD40EZAX / WD60EZAX to CMR (the newer EZAX revision is CMR; only the older EZAZ is SMR).
- **2026-06-16** - Initial public dataset: full specs, CMR/SMR classification, and full-year 2025 Backblaze annualized failure rates.
