## Methodology ## 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. - **CMR vs SMR** is classified from manufacturer datasheets and model-number decoding.

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. - **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).
