METHODOLOGY

Define the units before drawing conclusions

How data enters the system, how it is normalized and calculated, and when the model must admit failure.

v1.0 · 2026-08-09

Capacity is normalized to EB

1 EB = 1,000 PB = 1,000,000 TB. Rack capacity is shown in TB; annual market supply and demand are shown in EB. Unmet demand is not carried into the next year.

Data quality and versions

Stable IDs, raw-response hashes, pre/post conversion values, revision links and range checks provide traceability. New model versions never overwrite old judgements.

International SEO and publication boundaries

Every language has a distinct URL, self-referencing canonical and reciprocal hreflang set. Restricted raw data never enters the public API.

Formula

TB × rack count ÷ 1,000,000 = EB

Current-year gap = current-year demand − current-year supply; unmet demand is not carried forward.
