SharePoint vs OneDrive vs Google Drive for Small Business

Cloud storage for small business splits into three dominant options in 2026: Microsoft SharePoint, Microsoft OneDrive, and Google Drive. Most business owners see them as competing products, and try to pick one. They’re actually solving three different problems, and understanding the split is the difference between a smooth file storage strategy and a confused mess where employees can never find anything.

This guide walks through what each does, when each is right, and how to structure file storage for a small business without ending up with 4 copies of every document in 4 different places.

The three problems these tools solve

Cloud storage for a small business is really three separate problems:

1. Personal work storage: the files an individual employee is working on. Not shared, or shared narrowly with 1-2 collaborators.
2. Team / departmental storage: files shared across a project team, department, or working group. Shared with 5-50 people.
3. Company-wide file access: policies, templates, shared reference documents. Available to everyone in the company.

Each of these needs a different tool. SharePoint, OneDrive, and Google Drive each handle some subset of these — and the right architecture uses each where it fits.

OneDrive for Business — personal work storage

OneDrive is designed for individual employee file storage. Each person gets 1TB of cloud storage tied to their Microsoft 365 account. Files sync to their laptop via the OneDrive client. They can share individual files or folders with specific colleagues, but the storage is fundamentally personal.

Use OneDrive for: draft documents, personal work files, files that never leave one person’s control, work-in-progress not ready to share. Think of it as the cloud replacement for the “My Documents” folder on a Windows laptop.

Do NOT use OneDrive for: team-shared files, project workspaces, or any file where losing access to one person’s OneDrive would create problems. When an employee leaves, their OneDrive is retained for 30 days and then deleted (unless admin explicitly preserves). Team documents in a departing employee’s OneDrive are a data-loss risk.

SharePoint — team and company-wide storage

SharePoint is Microsoft’s team collaboration platform. It organizes files into “sites” — each site can be a team, a department, a project, or a company-wide resource area. Every Microsoft Teams team creates a SharePoint site behind the scenes to store its files.

Use SharePoint for: departmental shared drives (Marketing team files, Finance policies), project workspaces, company-wide reference (employee handbook, policies, templates), any file that belongs to a group rather than an individual.

SharePoint’s permission model is more flexible than OneDrive’s — you can grant per-site, per-folder, or per-file permissions to individuals, groups, or entire directories. The trade-off is complexity: SharePoint requires actual thought about site architecture and permissions, whereas OneDrive is fire-and-forget personal storage.

Google Drive — the alternative universe

Google Drive is Google Workspace’s equivalent to OneDrive + SharePoint combined. Every Google Workspace user gets a “My Drive” (like OneDrive — personal storage) and access to “Shared Drives” (like SharePoint — team storage).

Use Google Drive when: your business runs on Google Workspace instead of Microsoft 365, your primary productivity apps are Google Docs/Sheets/Slides, or you have a mixed Mac/Windows/Chromebook environment where Google’s cross-platform experience shines.

Do not run BOTH Google Drive and OneDrive as primary storage unless you have a very specific reason — it doubles the storage cost, splits company data, and forces employees to remember which files live where. Pick one primary platform and stick with it.

Feature comparison

The features that matter for small business:

• Storage limits: OneDrive 1TB/user (5TB with M365 E5). Google Drive 2TB-5TB/user depending on plan. SharePoint 1TB per site + 10GB per user in pooled tenant storage.
• Real-time co-editing: Google Docs/Sheets/Slides is the gold standard. Microsoft has caught up considerably with Office 365 web apps; still slightly behind Google on pure real-time collaboration UX.
• Desktop app integration: OneDrive integrates deeply with Windows File Explorer. Google Drive has “Drive for Desktop” that works but feels more like a mounted network drive.
• Search: Both have solid full-text search. Google’s is slightly faster; Microsoft’s now includes AI-powered semantic search via Copilot.
• Version history: Both keep 30 days by default; both allow indefinite retention with proper policies.
• Sharing: Both support internal + external sharing with expiration, password protection, and access levels (view / comment / edit).
• Mobile access: Both have solid iOS + Android apps.

Cost comparison

Basic small business pricing 2026:

• Microsoft 365 Business Basic ($6/user/month): web/mobile apps + 1TB OneDrive + Teams + Exchange + SharePoint. Cheapest full-featured M365.
• Microsoft 365 Business Standard ($12.50/user/month): adds desktop Office apps.
• Microsoft 365 Business Premium ($22/user/month): adds Intune device management + Entra ID P1 + Defender for Business.
• Google Workspace Business Starter ($7/user/month): web/mobile apps + 30GB Drive + Gmail + Meet + Docs/Sheets/Slides.
• Google Workspace Business Standard ($14/user/month): 2TB Drive.
• Google Workspace Business Plus ($22/user/month): 5TB Drive + Vault (compliance) + advanced security.

At the “starter” tier Google is $1 cheaper and gets more collaborative apps. At the “standard” tier Microsoft is slightly cheaper and adds desktop Office. At the “premium” tier they’re identical price, with Microsoft heavier on device management and Google heavier on compliance/security tools.

Migration paths

Common small business migrations:

• File server to SharePoint: the most common in 2026. Move company file shares from an on-prem file server to SharePoint sites organized by department/team. Preserves permission structure with some rework.
• OneDrive to SharePoint: for files that started as personal but became team documents. Move via the Move/Copy tool in the OneDrive web interface.
• Dropbox to Google Drive or OneDrive: Dropbox for Business declining in market share. Native migration tools from both Google and Microsoft.
• Google Drive to OneDrive (or vice versa): platform switches happen. Native migration tools work for most content; specialty tools (Multcloud, ShareGate) handle edge cases.

File server migrations are the biggest project — plan 30-90 days for a small business with a 500GB+ file server.

Permission architecture

The single most common small business file storage mistake: opening everything to “Everyone at company” for convenience. Result: sensitive files (HR records, financial reports, executive decisions) accessible to all employees. Once permissions are open, they’re never audited back to tighter.

Right approach: start with tight permissions, open them up deliberately as needed. In SharePoint: use Microsoft 365 Groups to control site membership. In Google Drive: use Shared Drives with specific membership. In both: HR, Finance, and Executive folders should have their own controlled access.

Audit permissions quarterly. Employees who move roles keep old permissions unless someone actively removes them. Over 2-3 years, permission sprawl is guaranteed without discipline.

Compliance and retention

For businesses with legal, financial, or industry regulatory obligations:

• Microsoft Purview (comes with M365 Business Premium and E5): retention policies, eDiscovery, data classification, DLP.
• Google Vault (comes with Business Plus and Enterprise): equivalent retention, eDiscovery, and legal hold.

Both platforms will hold data for the retention period you configure regardless of user deletion attempts. Critical for legal, healthcare, finance, and regulated industries.

What about hybrid setups

Some small businesses genuinely need both platforms — client requirements, acquisitions, or specific workflows. Common hybrid patterns:

• Primary M365, but the sales team uses Google Workspace because clients share Google Docs with them.
• Primary Google Workspace, but the finance team uses M365 because the accounting system integrates only with Microsoft.
• M365 for internal, Google Workspace for external collaboration channels.

Hybrid works but requires clear rules: which platform owns the master copy of what. Ambiguity leads to fragmentation. If you go hybrid, document the rules in writing.

Where identity fits in

File storage is authenticated against your identity platform — Entra ID for M365 (see our AD vs Entra ID guide), Google Workspace’s built-in identity for Google Drive. Getting identity right is the foundation for permissions working correctly.

External sharing (with clients, contractors, partners) works via guest accounts in Entra ID (for SharePoint) or guest accounts in Workspace (for Drive). Both are secure when configured with MFA and conditional access. Never share via “anyone with the link” for sensitive files — the link inevitably leaks.

Decision matrix

Which primary storage platform:

• Already using Microsoft 365: SharePoint + OneDrive. Don’t add Google Drive.
• Already using Google Workspace: Google Drive. Don’t add OneDrive.
• Greenfield decision, mixed OS environment: Google Workspace is slightly stronger for Mac + Chromebook + Windows mix; Microsoft 365 is stronger for Windows-heavy environments with legacy Office dependencies.
• Regulated industry (healthcare, financial, legal): Microsoft 365 Business Premium or E5 for compliance depth (Purview + Defender + Intune all integrated).
• Creative agency: Google Workspace for real-time collaboration; often paired with Adobe CC and Dropbox for large file handoffs.

Key takeaways

• OneDrive = personal storage; SharePoint = team + company storage; Google Drive = both (My Drive + Shared Drives).
• Use OneDrive for personal work, SharePoint for team documents — don’t put team files in personal OneDrive folders.
• M365 and Google Workspace are roughly cost-equivalent at similar tiers; pick one primary platform and stick with it.
• Permission sprawl is inevitable without quarterly audits. Start tight, open deliberately.
• File server → SharePoint migration is the most common small business project in this category — plan 30-90 days.

FAQ

Can I use both OneDrive and Google Drive at the same time? Technically yes, but it’s usually a mistake. Doubles storage cost, splits company data, forces employees to remember which files live where. Pick a primary platform. Use the other for specific integrations only if there’s a real business reason.

What happens to an employee’s OneDrive when they leave? By default, retained for 30 days then deleted. Admin can preserve content indefinitely via retention policy. Best practice: move any business-critical files from a departing employee’s OneDrive to a SharePoint site BEFORE offboarding, then let OneDrive delete per policy.

Is SharePoint really that different from a file server? Yes. SharePoint is document-management + collaboration + workflow, not just a file drive. It supports co-authoring, version history, metadata columns, retention policies, and integration with Teams/Outlook/Power Automate. File servers do none of that. Migration is a mindset shift, not just a location change.
