# ChooseCompute > ChooseCompute is an evidence-backed US hardware decision and cross-store price comparison service for NAS systems and NAS hard drives. It helps people and AI agents choose what to buy, understand trade-offs, and choose where to buy an exact configuration. Choose by need when the desired use case is known but the hardware is not. Use the database when an exact model, MPN, capacity, bay count, or specification is already known. Catalog scope is limited to current new-condition turnkey desktop or tower NAS systems sold in the United States and current manufacturer-positioned 3.5-inch SATA NAS hard drives. Rackmount systems, DAS, DIY-OS barebones, used or refurbished products, surveillance drives, desktop-only drives, SAS drives, and datacenter-only drives are excluded. The evidence snapshot contains 110 NAS configurations, 46 exact HDD SKUs, 24 checked NAS-and-drive bundles, five use cases, and 15 scenario-tier guides. The researched commerce set contains 520 exact product pages across 16 represented merchants, including 331 field-dated checked prices. Prices exclude tax and shipping unless explicitly stated. Affiliate relationships never affect product recommendations or price ordering. ## Decision tools - [ChooseCompute decision console](https://choosecompute.com/): Start with a use case or search the product and Offer databases. - [NAS and hard-drive database](https://choosecompute.com/nas): Filter and compare exact NAS configurations and HDD MPNs, specifications, checked prices, and merchant coverage. - [Recommendations by use case](https://choosecompute.com/nas/recommendations): Compare entry, midrange, and high-end complete builds for five storage scenarios. - [Scenario buying guides](https://choosecompute.com/nas/guides): Read evidence-supported explanations of why a configuration fits, where it does not, and which alternatives to consider. ## Use cases - [Home backup](https://choosecompute.com/nas/recommendations/home-backup): NAS and drive combinations for protected household backups. - [Photo library](https://choosecompute.com/nas/recommendations/photo-library): Storage choices for photographers and creator archives. - [Plex media](https://choosecompute.com/nas/recommendations/plex-media): NAS configurations for media libraries and playback workloads. - [Homelab and containers](https://choosecompute.com/nas/recommendations/home-server-containers): Systems for services, containers, and home-server experimentation. - [Small-office files](https://choosecompute.com/nas/recommendations/small-office-files): Shared storage with conservative redundancy for small teams. ## Evidence and interpretation - [Research methodology](https://choosecompute.com/methodology): Scope rules, source hierarchy, compatibility language, price freshness, bundle calculations, and known limitations. - [Affiliate disclosure](https://choosecompute.com/affiliate-disclosure): How merchant links and potential compensation are kept separate from recommendations and Offer ordering. - [About ChooseCompute](https://choosecompute.com/about): Product purpose, evidence model, and intended audience. - [XML sitemap](https://choosecompute.com/sitemap.xml): Complete index of the 214 public decision, product, bundle, and guide pages. ## Optional - [Privacy](https://choosecompute.com/privacy): Privacy information. - [Terms](https://choosecompute.com/terms): Research, compatibility, and dated-price limitations.
