Google Drive vs Dropbox vs OneDrive: Which Cloud Storage Is Worth It?
Free storage, prices per terabyte, and the one question that decides it: which phone and office apps do you already use?
The best cloud storage is usually the one that's already built into the stuff you use. If you have an Android phone and Gmail, that's Google Drive. If you use Windows and Microsoft Office, it's OneDrive. Dropbox is the best at the actual job of syncing files, and it's the most neutral, but you pay a little more for that.
Here's how they stack up.
Free storage
| Free storage | Notes | |
|---|---|---|
| Google Drive | 15 GB | Shared with Gmail and Google Photos |
| OneDrive | 5 GB | Shared with Outlook.com email |
| Dropbox | 2 GB | Barely enough for a few hundred photos |
Google wins easily on free space. The catch is that Gmail attachments and Google Photos eat into the same 15 GB, so "free" runs out faster than you'd think.
Paid plans
US prices as of October 2026:
- Google: 2 TB through Google One is about $9.99 a month. Google's new AI Plus plan, at $4.99 a month, includes 400 GB plus Gemini AI features, which is a great deal if you'd use both.
- OneDrive: you don't really buy OneDrive alone. Microsoft 365 Personal ($99.99 a year) gives you 1 TB of OneDrive plus Word, Excel, PowerPoint and Outlook.
- Dropbox: Dropbox Plus gives you 2 TB for about $10 to $12 a month depending on whether you pay yearly or monthly.
Best value per terabyte: Google, unless you'd pay for Microsoft Office anyway. Then OneDrive's storage is basically free.
Google Drive: best for Android and Gmail users
Why pick it: generous free tier, works beautifully with Google Docs, Sheets and Photos, and the search is excellent (it can find text inside images and PDFs).
Downsides: the desktop app is fine but not as polished as Dropbox's. And Google's storage being shared across Gmail and Photos confuses a lot of people when it fills up.
OneDrive: best for Windows and Office users
Why pick it: it's built into Windows. Your Desktop, Documents and Pictures folders can be backed up automatically with one setting. And if you pay for Microsoft 365, the 1 TB comes included.
Downsides: the 5 GB free tier is small, and Windows nags you about it. Mac and Android support is fine but clearly not its home turf.
Dropbox: best at syncing, most neutral
Why pick it: Dropbox started as a sync company and it's still the most reliable at it, especially with big folders and lots of small files. It works equally well on Mac, Windows, Linux, iPhone and Android, and lots of other apps integrate with it.
Downsides: the free plan's 2 GB is tiny, and it's the most expensive option if storage is all you need.
What about iCloud?
If your whole household is on iPhone and Mac, iCloud is the natural choice for photos and backups, and it's often the simplest. It's weaker on Windows and Android.
The one-question decision
Which ecosystem are you already in?
- Android, Gmail, Chromebook → Google Drive
- Windows, Microsoft Office, Outlook → OneDrive
- iPhone, Mac → iCloud (with Google Drive or OneDrive for sharing with others)
- A mix of everything, or you share big folders with clients → Dropbox
One last thing: cloud sync isn't a complete backup on its own. If you delete a file or ransomware scrambles it, that change syncs too. For a proper safety net, see The 3-2-1 Backup Rule, Explained.
