Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The market size is built upward from unit shipments of enterprise, midmarket and entry-level NAS arrays, split by capacity tier and controller class, multiplied by the realised average selling price each tier commands after typical channel discounting. Shipment volumes are drawn from storage hardware trade data and OEM production estimates; average selling prices are anchored to distributor and reseller pricing observed for comparable configurations. This bottom-up build is then checked against the storage-segment revenue disclosed by the major branded vendors in their own filings. Where the two diverge, the correction is made to the underlying shipment or price assumption feeding the bottom-up build, not by averaging the two figures together.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary interviews target storage procurement and infrastructure leads at enterprise IT buyers, channel and systems-integrator partners who resell NAS hardware, and product and pricing managers at the branded vendors themselves, since they can speak to realised street pricing that list prices do not reflect. Regulatory and compliance contacts are included where data-residency or retention rules shape purchasing, particularly in financial services and healthcare. Sampling is weighted toward North America, Europe and the larger Asia Pacific markets, where the branded vendors concentrate their own reporting and where enterprise NAS spending is most concentrated, with lighter coverage extended into Latin America and the Middle East and Africa to confirm regional demand direction rather than to size those markets independently.

Secondary sources, this report

Desk research draws on company annual reports and investor disclosures from the major branded vendors, customs and trade classification data for networked storage hardware, and IT hardware shipment tracking published by industry analyst services. Data-center capacity and construction pipeline reports are used to anchor regional demand, and public-sector and enterprise IT procurement records are checked where available to confirm large-account purchasing. Storage-industry trade association benchmarks on capacity and interface standards are used to validate the technology-tier splits used in the bottom-up build.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built on continued growth in unstructured and AI-training data volumes, the pace at which enterprises shift file workloads from direct-attached and legacy SAN storage onto NAS, and the rate at which hybrid-cloud tiering is adopted alongside on-premises capacity. Pricing is assumed to keep falling per unit of capacity while overall spend rises because volume growth outpaces the price decline. The forecast normalizes for the unusually sharp remote-work-driven demand step-up recorded in 2020 and 2021, treating that period as a level shift rather than a trend to extrapolate forward. For the forecast to hold, enterprise data growth and AI workload adoption both need to continue at broadly their recent pace.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Outputs are back-tested against recorded shipment and revenue growth for the historical 2020-2024 period to confirm the bottom-up build reproduces observed trends before it is extended forward. Segment and regional shift assumptions, such as the move toward scale-out architectures and the growing Asia Pacific share, are reviewed against what interviewed buyers and channel partners describe as their own purchasing plans. Sensitivities are tested around the pace of cloud-hybrid adoption and around a slower AI-driven data growth scenario, since both are the assumptions the forecast depends on most heavily, and the resulting range is reflected in the bull and bear scenarios rather than collapsed into a single number.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is strongest for the high-end enterprise tier and for North America and Europe, where branded-vendor disclosures and channel data are most complete. It is weaker for the entry-level and midmarket tiers, where a larger share of volume moves through white-label and regional vendors that do not publicly disclose revenue, and for Latin America and the Middle East and Africa, where reporting is thinner and estimates lean more heavily on trade data and proxy indicators. A structural risk that would force a revision is a faster-than-expected shift of file workloads to fully managed cloud storage, which would reduce on-premises NAS unit demand.
