That file server in your office closet is a liability. It’s slow, it’s not backed up properly, nobody can access files from home, and when it dies: and it will die: you’ll lose everything that wasn’t manually copied somewhere else.

Cloud storage fixes all of this. Your files live in a secure data center, accessible from anywhere, automatically backed up, and shareable with your team (and external collaborators) without emailing attachments back and forth.

But which platform? Google Drive, OneDrive, Dropbox, Box: they all store files. The differences are in collaboration features, integrations, security controls, and how well they fit into the rest of your workflow. Here’s the breakdown.

Quick Picks

• Best for Google-native teams: Google Workspace ($7-18/user/mo)
• Best for Office-native teams: Microsoft 365 ($6-22/user/mo)
• Best for external sharing: Dropbox Business ($15-24/user/mo)
• Best for compliance + enterprise: Box ($15-35/user/mo)
• Best for zero-knowledge encryption: Proton Drive or Tresorit (pricing varies — see below)
• Best for Apple-only solopreneurs: iCloud+ ($0.99-9.99/mo)

Google Workspace (Google Drive): Best for Google-Native Teams

Price: $7-18/user/mo (Business Starter to Business Plus)

If your team already lives in Google Docs, Sheets, and Slides, Google Drive is the obvious choice. It’s not just storage: it’s the file layer underneath your entire collaboration workflow. Create a doc, it’s automatically saved to Drive. Share a folder with your team, everyone has access instantly.

The $7/user Business Starter plan gives you 30GB per user. The $14/user Business Standard plan bumps that to 2TB per user with additional features like shared drives (team-owned storage that doesn’t disappear when someone leaves). For most small teams, Standard is the sweet spot.

Real-time collaboration on Google Docs, Sheets, and Slides is still best-in-class. Multiple people editing simultaneously with no file conflicts, instant autosave, and version history going back forever.

Who it’s for: Teams that use Google Docs for their daily work. Startups, agencies, and knowledge workers who prioritize collaboration over complex file structures. Teams with remote or distributed members. Also pairs well with tools like Slack or Discord for communication.

Limitations: If your team primarily uses Microsoft Office files (.docx, .xlsx), the constant format conversion is annoying. File organization can get messy without discipline: Google Drive’s folder structure is less intuitive than traditional file systems. Limited offline access compared to Dropbox.

Microsoft 365 (OneDrive + SharePoint): Best for Office-Native Teams

Price: $6-22/user/mo (Business Basic to Business Premium)

If your team runs on Word, Excel, and PowerPoint, Microsoft 365 gives you 1TB of OneDrive storage per user plus SharePoint for team document libraries. You get the full Office suite (desktop apps, web apps, and mobile) plus cloud storage integrated throughout.

OneDrive works like a cloud-synced folder on your computer. Save files locally, they sync automatically. SharePoint provides team sites for shared documents with version control, permissions, and workflow automation. Together they replace both your file server and your document collaboration setup.

The co-authoring experience in Word and Excel has caught up to Google Docs: multiple people can edit simultaneously in both web and desktop apps. The advantage over Google is that you’re working in actual Office formats natively, no conversion needed.

Who it’s for: Businesses that rely on Microsoft Office applications. Companies with compliance requirements (Microsoft’s admin controls are extremely granular). Teams that also need email: Microsoft 365 includes Exchange email with business plans.

Limitations: SharePoint has a learning curve for setup and administration. The difference between OneDrive, SharePoint, and Teams file storage confuses people. Sync conflicts happen more often than with Google Drive. The admin interface is complex: you’ll want a dedicated IT person for larger teams.

Dropbox Business: Best for External Sharing

Price: $15-24/user/mo (Essentials to Business Plus)

Dropbox does one thing better than anyone else: making file sharing effortless. Send a link to anyone: client, vendor, contractor: and they can access files without creating an account, downloading an app, or figuring out permissions. The recipient experience is simply better than Google Drive or OneDrive sharing links.

For teams that regularly share large files with external parties (design agencies, real estate firms, media companies, consultants), Dropbox reduces friction. Transfer lets you send files up to 100GB to anyone. Paper provides lightweight collaborative docs. And the desktop sync is rock-solid: it just works in the background.

Smart Sync keeps files accessible without eating all your local disk space. Files appear in your regular folder structure, but download only when you open them.

Who it’s for: Creative agencies, consulting firms, real estate businesses, and any team that regularly shares large files with external clients and partners. Teams that want dead-simple sync without thinking about it.

Limitations: Per-user pricing adds up quickly for larger teams. The collaboration features (Paper, shared docs) aren’t as polished as Google Docs or Office. No bundled email or productivity apps: it’s purely storage and sharing. Less granular admin controls than Microsoft 365 or Box.

Box: Best for Compliance and Enterprise

Price: $15-35/user/mo (Business to Enterprise)

Box is cloud storage built for industries that care about security, compliance, and governance. Healthcare, financial services, government, legal: anywhere that has regulations about how files are stored, who can access them, and how long they’re retained.

The platform offers granular permissions (down to individual file level), detailed audit logs, data loss prevention, automated retention policies, and compliance certifications for HIPAA, FedRAMP, FINRA, and more. If an auditor asks “who accessed this file and when,” Box has the answer.

Box also has a strong workflow layer: you can build approval processes, automated routing, and metadata-driven organization on top of basic file storage.

Explore Box for business before selecting a tier, because storage, governance, and AI entitlements differ by plan.

Who it’s for: Regulated industries (healthcare, financial services, legal, government). Companies with 50+ employees that need IT governance over files. Organizations that have passed the “throwing files in a shared drive” stage and need structured content management.

Limitations: Overkill and overpriced for small teams without compliance needs. The collaboration features lag behind Google and Microsoft. Setup and administration requires IT involvement. Not the best choice if you just need simple storage and sharing.

Proton Drive and Tresorit: Best for Zero-Knowledge Encryption

Box answers “can we prove who accessed this file and when” with compliance certifications and audit logs. Proton Drive and Tresorit answer a different question entirely: “can the provider itself ever read our files?” All the platforms above (Google Workspace, Microsoft 365, Dropbox Business, Box) encrypt your data in transit and at rest, but the provider holds the decryption keys — which means the company, and anyone who successfully compels or breaches the company, can technically access your unencrypted files. Proton Drive and Tresorit use zero-knowledge, end-to-end encryption instead: encryption happens on your device before anything uploads, the provider never holds your key, and they genuinely cannot decrypt your files even if legally compelled to try.

This distinction matters most for businesses handling client, legal, financial, or health data where “the vendor promises not to look” isn’t a strong enough guarantee — law firms, healthcare providers, financial advisors, and any team whose contracts or compliance obligations require provable data isolation from the storage vendor itself.

Tresorit positions itself toward regulated industries (finance, legal, healthcare) with business plans reported starting around $19/user/month (annual billing, typically with a 3-user minimum) — confirm current pricing directly on tresorit.com, since it renders dynamically and this figure is sourced from third-party review coverage, not a fixed number pulled from Tresorit’s own pricing page in this research pass. It includes granular permission controls and dedicated secure data-room features (Tresorit Engage) for client-facing workflows. Explore Tresorit for controlled client-file sharing.

Proton Drive offers encrypted cloud storage with personal and business packages. Compare storage, sharing and administration on Proton’s business plan page; do not assume a consumer plan includes your required business controls or compliance agreement. We have withdrawn the earlier third-party price and minimum-seat quote. Swiss headquarters do not remove a customer’s obligations under other applicable privacy laws.

Evaluate Proton Drive for encrypted client-file storage. The approved link currently enters a consumer private-cloud-storage landing page. Teams should check the business plan page above before buying; this link does not promise a business checkout. For minimum seats, file-size limits and annual bills at two, three and ten people across Box, Tresorit and Proton Drive, Get Price Pulse’s secure small-team storage cost guide prices those requirements.

Who it’s for: Regulated or client-sensitive businesses (law firms, healthcare, financial services, and any consultancy handling confidential client data) where the purchase decision is specifically about who can technically access your files, not just who’s certified to store them. Not necessary for teams whose main concern is day-to-day collaboration convenience — Google Workspace, Microsoft 365, or Dropbox Business remain the better fit there.

Limitations: Encrypted-data recovery depends on configuring recovery methods in advance. Proton documents recovery using a previous password, recovery phrase or recovery file. An account password reset alone does not establish access to previously encrypted files; verify the recovery options for your chosen provider before relying on it. Both platforms also have thinner third-party-app integration ecosystems than Google Workspace or Microsoft 365, since deep integrations are harder to build without the provider being able to read file contents.

iCloud+: Best for Apple-Only Solopreneurs

Price: $0.99-9.99/mo (50GB to 12TB)

If you’re a one-person operation running entirely on Apple devices (Mac, iPhone, iPad), iCloud+ provides seamless storage with zero configuration. Files save to iCloud Drive automatically, sync across all your devices instantly, and integrate with native apps like Pages, Keynote, and Numbers.

At $2.99/month for 200GB or $9.99/month for 2TB, the pricing is simple and affordable for individual use. You also get iCloud Private Relay, custom email domain support, and HomeKit Secure Video storage included.

Who it’s for: Solo freelancers, consultants, and creators who work exclusively within the Apple ecosystem and don’t need to collaborate with a team or share files with external parties frequently.

Limitations: Terrible for teams: no real collaboration features, basic sharing options, and no admin controls. Windows and Android support exists but is clunky. No business-grade security or compliance features. You outgrow this quickly once you hire your first employee.

How to Choose

What ecosystem are you in? If you use Google Workspace for email and docs, use Google Drive. If you use Microsoft 365, use OneDrive/SharePoint. Don’t fight your ecosystem: the integrated experience is worth more than slightly better features on a competing platform.

Do you share externally a lot? Dropbox wins for external sharing because the recipient experience is frictionless. Google and Microsoft sharing works but can be confusing for external parties who don’t use those platforms.

Do you have compliance requirements? Box is the answer for regulated industries. Microsoft 365 Business Premium also has strong compliance tools but requires more configuration.

Are you just one person? iCloud+ (Apple) or Google Workspace Starter (everyone else) is plenty. Don’t pay for team features you won’t use.

Refer to our Notion pricing breakdown if you’re also looking for a knowledge management layer on top of your file storage.

The Bottom Line

For most small businesses, the choice comes down to Google Workspace or Microsoft 365: whichever matches the productivity apps you already use. If external file sharing is your priority, add Dropbox Business. If compliance drives your decision, invest in Box. And if you’re a one-person Apple shop, iCloud+ does the job quietly.

FAQ

How much cloud storage does a small business actually need?

Most small businesses need 1-2TB per user for comfortable usage. Google Workspace Business Standard (2TB/user at $14/month) or Microsoft 365 Business Basic (1TB/user at $6/month) covers the majority of teams. If you work with large files (video, design, CAD), budget for more. Start with a standard plan and upgrade individual users who hit limits.

Is cloud storage secure enough for sensitive business files?

Yes, for most business needs: all major providers use enterprise-grade encryption (in transit and at rest), redundant data centers, and meet SOC 2 and ISO 27001 standards. They’re more secure than your office file server, which likely has no encryption, no redundancy, and questionable access controls. One important distinction worth understanding: Google Workspace, Microsoft 365, Dropbox, and Box all hold the decryption keys themselves, meaning the provider can technically access your files if compelled to. Proton Drive and Tresorit use zero-knowledge encryption instead, where the provider never holds your key and genuinely cannot decrypt your files. For most businesses, provider-held-key encryption plus SOC 2/ISO 27001 compliance is sufficient. For businesses with specific client, legal, or regulatory requirements around who can technically access data, zero-knowledge options are worth the tradeoff in convenience. Enable two-factor authentication for all users regardless of which model you choose.

Can I migrate from a local file server to cloud storage?

Yes, but plan the migration carefully. Most providers offer migration tools (Google’s Transfer utility, Microsoft’s SharePoint Migration Tool). For small amounts of data, drag-and-drop works. For large migrations (10TB+), consider hiring a migration specialist. Budget 2-4 weeks for a typical small business migration including testing and training.

What happens to files when an employee leaves?

Google Workspace and Microsoft 365 let admins transfer file ownership to another user before deleting the departing employee’s account. SharePoint and shared drives retain files regardless of individual user changes. Set up a standard offboarding process that includes file transfer. On personal Dropbox or iCloud accounts, files belong to the individual: another reason to use business plans.

Can I use multiple cloud storage platforms together?

Technically yes, but it creates confusion. Teams end up with files scattered across platforms and nobody knows where to look. Pick one primary platform for internal files and stick with it. You might use a second platform for a specific purpose (Dropbox for client sharing while using Google Workspace internally), but keep the primary storage centralized.
