Firmex caps drag-and-drop at 10GB. Datasite bills per page. Above 10GB, most VDRs break — costs go vertical or files start splitting. Peony Business at $40 per admin per month delivers unlimited storage, NDA-gated downloads, dynamic watermarks, and screenshot protection without the cliff.
The 10GB cliff is the file-volume threshold where legacy VDR pricing models and upload limits stop working for modern deal data. Below 10GB, your deal data is mostly paper — contracts, financial models, investor memoranda — and per-page or per-project pricing is approximately fair. Above 10GB, the composition shifts to drone imagery, BIM models, drilling videos, MRI imaging, full-genome sequencing files, and 3D resource models that legacy VDRs were never priced for.
Three things break above the 10GB threshold on legacy VDRs. First, hard upload caps: Firmex caps drag-and-drop at 10GB exactly; Intralinks' single-file cap is 25GB; Ideals starts at 0.5GB storage and forces tier upgrades. Second, per-page billing renders raw data as inflated page counts: Datasite charges roughly $0.60 per page, so a 15GB deal renders as 12,000–25,000 pages and bills $7,200–$15,000 in per-page fees alone — most of those "pages" being slices of imagery and CAD files where the seller's actual unit cost is a fraction of a cent. Third, storage overages and tier upgrades stack on top of base contract value, with buyer-reported per-deal overages of $1,000–$5,000.
Peony Business at $40 per admin per month delivers unlimited storage per admin seat with no per-GB or per-page surcharges, integrated NDA gates, dynamic watermarks, screenshot protection, and page-level analytics — the rare combination above the 10GB cliff. Full breakdown: Best Data Rooms for Large Files (With NDA Gates).
Peony Business at $40 per admin per month delivers unlimited storage per admin seat with no per-GB or per-page surcharges, integrated NDA gates, dynamic watermarks, screenshot protection, and page-level analytics — the rare combination that handles 30GB+ deal data without forcing you to choose between file-size capacity and external-counterparty security. Full breakdown: Best Data Rooms for Large Files (With NDA Gates).
Firmex caps drag-and-drop at 10GB. Datasite renders 15GB deals as 12,000+ pages at $0.60 each ($7,200+ in per-page fees alone). Above 10GB, Peony Business at $40/admin/month is the only platform that holds price flat regardless of data volume.
Drone imagery, drilling videos, NI 43-101 reports, BIM models, MRI imaging, and CAD files upload at full size through chunked parallel transfers. No 10GB drag-and-drop ceiling, no per-page rendering surcharges, no per-format fees.
Counterparties sign your NDA template via integrated e-signatures before any document is visible. Every page they view is watermarked with their identity and timestamp. Screenshot protection blocks captures across desktop and mobile.

The 10GB cliff is the file-volume threshold where legacy VDR pricing models and upload limits stop working for modern deal data. For your 5-person M&A boutique, the cliff matters because of four concrete vendor limits: (1) Firmex's drag-and-drop upload caps at exactly 10GB — above that, you split files (which corrupts geological databases, multi-page TIFFs, and BIM model dependencies) or shift to slower API uploads; (2) Datasite charges roughly $0.60 per page, so a 15GB deal renders as 12,000–25,000 pages billed at $7,200–$15,000 in per-page fees alone, before storage overages and user surcharges; (3) Intralinks' single-file cap is 25GB in US/Germany/Australia — common 30GB+ engineering deliverables and drilling videos still force splits; (4) Ideals starts at 0.5GB storage with mandatory tier upgrades and per-GB negotiations above 10GB. Below the cliff, deals are mostly paper (CIMs, financial models, contracts) and per-page or per-project pricing is approximately fair. Above 10GB, Peony Business at $40/admin/month gives 5 admins unlimited storage, NDA gates, dynamic watermarks, and screenshot protection for $2,400/year flat — whether deals run 5GB or 50GB.
Yes. For your 4-person mining-finance fund, Peony Business at $40/admin/month gives you unlimited storage per admin seat — no per-GB surcharges, no per-page fees, and no file count caps. A typical buy-side review of 35GB of NI 43-101 reports, drill databases, drone imagery, and 3D resource models uploads at full size. Across 12 deals per year (420GB total), your fund's $1,920/year covers all 4 admin seats and all 12 NDA-gated rooms. Datasite would charge $20,000–$40,000 per deal at typical per-page rates, billing your 35GB review as 30,000–60,000 pages at $0.60 each. Peony's flat per-admin model is built for modern deal data composition where raw imagery, video, and CAD files dominate page counts.
Yes. For your 5-person infrastructure PE firm, Peony Business at $40/admin/month handles 60GB+ BIM models, AutoCAD .DWG files, and engineering drawings with unlimited storage, integrated NDA gates, and dynamic watermarks tied to viewer identity. Each syndicate partner must sign your fund's NDA template via integrated e-signatures before viewing any documents, and every page they view is stamped with their name and timestamp. Box Enterprise Advanced supports 500GB single-file uploads but lacks NDA gates, watermarks, and screenshot protection — you'd need third-party add-ons. Datasite and Intralinks both support large CAD uploads but charge per-page or per-GB, pushing 60GB engineering deals to $30,000–$80,000.
Yes. For your 3-person biotech-focused fund, Peony Business at $40/admin/month supports 40GB+ uploads of MRI/CT imaging, full-genome sequencing files, and clinical trial master files (TMFs) with unlimited storage, NDA gates that licensing partners must sign before viewing, and HIPAA-ready audit trails. Dynamic watermarks stamp every page (including high-resolution imaging) with the licensing partner's name, email, and timestamp. Screenshot protection blocks captures of imaging studies and trial protocols. The combination — large-file support, NDA gates, watermarks, screenshot blocking, and HIPAA-ready audit trails — is rare; competitors like LucidLink and Egnyte handle large files but skip NDA enforcement entirely.
For your 6-person boutique IB, Peony does not impose the kind of hard upload caps that Firmex (10GB drag-and-drop) or Intralinks (25GB single file in US/DE/AU) enforce. Large-file uploads use chunked parallel transfers backed by a global CDN, so 30GB+ engineering data, drone imagery, drilling videos, and BIM models upload reliably without splitting. Median time from data room creation to live counterparty access is 4 minutes 19 seconds. Your team can have a 35GB sell-side mandate uploaded, NDA gates configured, dynamic watermarks set, and bidder access distributed before lunch on Monday — the workflow Firmex's per-project model can take 1–4 weeks to set up.
For your 7-person mining merchant bank, per-admin pricing is built around modern deal data composition where raw geospatial, imaging, and CAD volume dominates page counts. Datasite and Intralinks were designed in the 2000s for paper-heavy M&A — sell-side mandates with 5,000–50,000 pages of contracts, financials, and legal documents — when 'page' was the unit of work. For your buy-side mining diligence today, a single deal might include 50 pages of an investment memorandum but 35GB of geological surveys, drone imagery, and CAD models. Per-page billing massively overcharges for raw data uploads (a 2GB drilling video billed as 500 'pages' at $0.60 = $300) when the seller's actual unit costs are pennies. Peony's flat per-admin fee with unlimited storage aligns price with value for data-heavy deals.
Yes. For your 4-person architecture firm sharing 80GB of Revit and BIM models with developer clients, Peony Business at $40/admin/month covers unlimited storage across all 4 admin seats — every project room, every client deliverable, every revision history. NDA gates require developer clients to sign your firm's confidentiality agreement before downloading any Revit or AutoCAD files. Dynamic watermarks stamp every viewed document with the client's name and timestamp, and instant access revocation cuts off a client when a project ends. Box Enterprise Advanced supports 500GB single uploads but has no NDA gates or dynamic watermarks; LucidLink streams BIM files instantly but offers no client-facing access controls or audit trails.
Yes. For your 5-person specialty credit fund evaluating 8 deals per quarter, Peony Business at $40/admin/month covers unlimited storage indefinitely — closed deal rooms remain in your account with full data integrity for compliance and audit purposes, and you can reopen, re-share, or revoke access at any time. There are no archival fees, storage tier downgrades, or data retention surcharges. Most legacy VDRs (Datasite, Firmex, Intralinks) bill per-project and either delete data or charge separate retention fees once a project ends. For a fund running 32 deals per year, Peony keeps a complete deal-history archive at the same $40/admin/month — useful when an LP asks about a deal you reviewed two years ago.
Yes. For your 8-person infrastructure debt fund, Peony Business at $40/admin/month includes unlimited storage plus AI document chat, Smart Q&A, AI auto-indexing, AI Rooms, and AI extraction across every data room you create. Your fund can spin up unlimited rooms (one per asset under review) and query technical reports, environmental assessments, and financial models in natural language — getting cited answers with exact page references. Smart Q&A handles syndicate partner questions: counterparty submits a question, AI drafts a response from your uploaded documents, your team reviews and approves, and only approved answers are published. Datasite and Intralinks ship neither AI chat nor Smart Q&A on standard contracts; both are extra-cost add-ons or absent entirely.
Unlimited rooms on Business with AI auto-indexing, page-level analytics, and full audit trails.
