Every major cloud storage provider gives you a small amount of space for free and then tries to upsell you into its wider productivity ecosystem. The real differences between Dropbox, Google Drive, and OneDrive in 2026 show up in how storage is packaged, what counts as a “plan,” and how deeply each one is tied to its parent company’s office suite.
At a Glance
| Dropbox | Google Drive / Google One | OneDrive / Microsoft 365 | |
|---|---|---|---|
| Free storage | 2GB | 15GB (shared across Gmail, Drive, Photos) | 5GB |
| Cheapest paid storage | Plus: $9.99/mo for 2TB | Basic: 100GB, ~$19.99/yr standard rate | Microsoft 365 Basic: $1.99/mo for 100GB |
| Standalone storage-only plan? | Yes | Yes (Google One) | No — always bundled with a Microsoft 365 tier |
| Office suite included | No (third-party integrations instead) | Yes, Docs/Sheets/Slides | Yes, Word/Excel/PowerPoint (on higher tiers) |
Short Verdict
If you just want cheap bulk storage with no office suite attached, OneDrive’s $1.99/mo Microsoft 365 Basic tier for 100GB is hard to beat on price, though it’s technically a Microsoft 365 plan rather than a pure storage product. If you want storage bundled with the most capable free collaborative office suite, Google Drive (via Google Workspace or Google One) wins. If you want the most mature third-party integrations, sharing controls, and e-signature tools independent of any office suite, Dropbox is still the most flexible, business-focused option, at a higher starting price.

Google Drive / Google One Pricing
Every Google account comes with 15GB shared across Gmail, Drive, and Photos at no cost. Beyond that, Google One sells storage in tiers that Google has recently repackaged around its “Google AI” branding, and it has run promotional first-year pricing that reverts to a standard annual fee after 12 months. As of this research, the standard (non-promotional) annual pricing reported was roughly $19.99/year for a 100GB Basic plan and roughly $99.99/year for a 2TB Premium plan, with a higher “AI Pro” 2TB tier around $199.99/year that bundles expanded Gemini AI features. Because Google has run limited-time discounted introductory pricing on these same tiers, confirm the live price at one.google.com/about/plans before buying, since the promotional and standard rates differ meaningfully.
OneDrive / Microsoft 365 Pricing
Microsoft no longer sells a storage-only consumer OneDrive plan. Instead, OneDrive capacity is bundled into Microsoft 365 tiers:
- Free Microsoft account: 5GB of OneDrive storage.
- Microsoft 365 Basic: $1.99/mo (about $19.99/yr) — 100GB storage, ad-free Outlook and some extra security, but no desktop Office apps.
- Microsoft 365 Personal: $9.99/mo or $99.99/yr — 1TB storage, full desktop Office apps, for 1 person.
- Microsoft 365 Family: $12.99/mo or $129.99/yr — a shared storage pool (recently restructured; multiple independent outlets reported Microsoft shifted this from a per-person 1TB allotment to a smaller shared pool across up to 6 people in 2026) for up to 6 people.
Microsoft also sells standalone OneDrive for Business plans, but these are being retired: new sales end May 31, 2026, no renewals are accepted after January 2027, and the plans shut down entirely in December 2029, pushing business customers toward bundled Microsoft 365 Business tiers instead.
Features Beyond Storage
All three claim AES-256 encryption at rest and TLS in transit, offline sync, and link-based sharing with permission controls. Google Drive and OneDrive both have deeper native co-editing through their own office suites (Docs/Sheets vs. Word/Excel Online); Dropbox has no first-party office suite and instead focuses on third-party app integrations and its own e-signature product, Dropbox Sign.
Pros and Cons
- Dropbox pros: mature sharing/permission controls, strong third-party app ecosystem, Dropbox Sign built in. Cons: smallest free tier (2GB), no bundled office suite, priciest entry paid tier.
- Google Drive pros: generous 15GB free tier shared across Google services, tightly integrated with Docs/Sheets/Slides and Gemini AI. Cons: plan names and prices have shifted repeatedly around AI branding, making it harder to compare long-term cost.
- OneDrive pros: cheapest path to 100GB via Microsoft 365 Basic, deep Word/Excel/Outlook integration on higher tiers. Cons: no pure storage-only plan, recent reports of Family plan storage being reduced from a per-person to a shared pool.
Who It’s a Good Fit For
Dropbox suits businesses that need strong sharing/permission controls and e-signature without committing to an office suite. Google Drive suits anyone already using Gmail and Google Workspace who wants the most storage for free and native Docs collaboration. OneDrive suits Windows and Microsoft 365 households that want the cheapest path to meaningful storage, as long as they’re comfortable buying it as part of a Microsoft 365 subscription rather than a standalone product.
Bottom Line
There’s no pure storage-only winner anymore — Google and Microsoft both tie meaningful storage to their broader AI and office ecosystems, and Microsoft has eliminated the standalone OneDrive consumer plan entirely. Dropbox remains the most “just storage and sharing” focused of the three, at a real price premium. Pick based on which ecosystem (Google Workspace, Microsoft 365, or neither) you’re already paying for.
FAQ
Can I buy OneDrive storage without a Microsoft 365 subscription?
No. Microsoft has discontinued standalone OneDrive consumer storage plans; all paid OneDrive storage now comes bundled with a Microsoft 365 tier.
How much free storage does each service give?
Dropbox gives 2GB free, Google gives 15GB shared across Gmail/Drive/Photos, and OneDrive gives 5GB free with any Microsoft account.
Which is cheapest for just storage?
Microsoft 365 Basic at roughly $1.99/mo for 100GB is currently the cheapest entry point, though it includes some Outlook and security features beyond raw storage. Always confirm current pricing directly with the vendor, since all three have changed their plans within the past year.
