OneDrive vs Google Drive vs Dropbox: Storage and Prices Compared

Google Drive and Microsoft OneDrive are the cheapest way to buy 2TB of cloud storage, at $9.99 a month, and both throw in a full office suite once you're paying anyway. Dropbox charges the same $9.99 a month for 2TB but has no free office suite bundled in, and its free tier is far smaller than the other two. Which one is worth paying for depends less on price than on which ecosystem already runs your files: Windows and Office push you toward OneDrive, Gmail and Chromebooks push you toward Google Drive, and cross-platform teams that don't want to be tied to either often end up on Dropbox anyway, for its sync engine.

Storage tiers and prices compared

All three services follow the same basic shape: a small free allowance, a cheap low-capacity paid tier, and a 2TB-class tier that's the effective "serious user" plan. Where they differ is what that 2TB tier includes and how storage is bundled with other software.

On the Microsoft side, there's no way to buy OneDrive storage on its own anymore. Microsoft 365 Basic replaced the old standalone 100GB OneDrive plan, so the cheapest paid tier is a full Microsoft 365 subscription that happens to skip the desktop Office apps. Google, by contrast, still sells storage-only Google One plans, and layers optional Gemini AI features on top as separate, pricier tiers rather than folding AI into the base storage price. Dropbox sells storage with no office-suite angle at all; its Plus plan is pure storage plus sync tooling.

Two things stand out. First, the $1.99-for-100GB entry price is identical between Microsoft and Google, and Dropbox doesn't compete at that tier at all — its cheapest paid step jumps straight to 2TB. Second, the $9.99 2TB price point is where OneDrive quietly disappears from the comparison: Microsoft's $9.99/month plan is 1TB with Office apps, not 2TB of raw storage, so a straight storage-per-dollar comparison actually favors Google One and Dropbox at that price, not Microsoft.

Free-tier limits

If you never intend to pay, the free tiers aren't close. Google's 15GB is the largest of the three, but it's a shared pool: every photo backed up at original quality, every Gmail attachment and every Google Docs file eats into the same 15GB, so heavy Gmail users can burn through it without touching Drive at all. Microsoft's free 5GB is smaller and also shared with OneDrive-connected apps, though a separate Outlook.com mailbox gets its own 15GB. Dropbox's free Basic tier is the smallest by far, at 2GB, and Dropbox also caps how many devices a free account can link, which matters more than the gigabyte number for anyone syncing a phone, a laptop and a work PC at once.

File size and sharing limits

Beyond the headline storage number, the practical limit most people actually hit is how large a single file can be before it won't upload or sync at all, and how sharing links behave once you send them outside your own account. Microsoft's support documentation lists a 250GB maximum individual file size across current OneDrive and Microsoft 365 plans, which comfortably covers everything short of professional video-editing project files. Dropbox advertises a 50GB single-file transfer limit on its Plus plan, rising to 100GB on the Standard and Advanced business tiers — smaller than OneDrive's ceiling, though still far above what a typical document, spreadsheet or photo library needs. All three let you generate shareable links with optional passwords and expiry dates on their paid tiers; Microsoft 365 Basic and Personal both include password-protected, expiring links as a named security feature rather than an add-on, which is worth knowing if link security is a specific reason you're paying at all.

File sync and offline access

All three now default to "cloud-first" sync clients that don't mirror your entire library to local disk unless you ask them to — a shift all three made specifically to stop cloud storage from silently filling up laptop SSDs.

• OneDrive uses Files On-Demand: files show up as placeholders with a cloud icon and only download when opened, or you can mark specific files or folders "Always keep on this device" for guaranteed offline access. It's deeply wired into Windows 11's own File Explorer, which is the main practical edge for Windows users.
• Google Drive's desktop client offers two modes — Stream files (cloud-first, make individual items available offline on demand) or Mirror files (a full local copy of everything, always offline). Google's own help documentation is explicit that streamed files only stay accessible offline while the Drive for desktop app is running and signed in.
• Dropbox pioneered this pattern years ago with Smart Sync (online-only vs. local files) and still has the most mature selective-sync controls of the three, plus Dropbox Rewind, which can roll back an entire folder or account to a point in time — useful after a ransomware attack or a bad bulk-delete, not just a single file.

Office and Workspace integration

This is where the three products diverge the most, because only two of them are attached to a productivity suite at all.

OneDrive is the native storage layer for Microsoft 365: Word, Excel and PowerPoint save straight to it, support real-time co-authoring, and integrate with Windows 11's search and Recall-style features without any extra setup. If you're deciding whether to keep an old perpetual copy of Office or move to a subscription, it's also worth knowing that Office LTSC 2021 reaches end of support on October 13, 2026, which is pushing more households onto Microsoft 365 — and OneDrive storage — anyway.

Google Drive plays the same role for Google Workspace: Docs, Sheets and Slides live in Drive natively, and Google One Premium specifically layers Workspace's premium collaboration features (like longer Meet calls and more Gmail aliases) on top of the base 2TB. Dropbox has no equivalent first-party office suite; it instead leans on Dropbox Paper for lightweight docs and integrations with Slack, Zoom and Microsoft's own Office apps via add-ins, which makes it a reasonable neutral choice for teams that already use a mix of Google and Microsoft tools and don't want to standardize on either one's storage.

Privacy and security posture

All three encrypt data both at rest and in transit and support two-factor authentication, so the practical differences are in recovery windows and account-level protections rather than baseline encryption.

Per Dropbox's own security page, files are protected with 256-bit AES encryption at rest and TLS/SSL in transit; deleted-file recovery runs 30 days on Plus, 180 days on Standard and a full year on Advanced, and Dropbox Rewind adds account-level rollback plus continuous dark-web breach monitoring. Microsoft 365 Basic and Personal both include OneDrive ransomware detection and recovery (restoring files from before an attack, within a 30-day window) and Personal Vault, a PIN- or biometric-locked area for sensitive files, per Microsoft's storage FAQ. Google ties Drive into its broader account security stack, including two-step verification and the stricter Advanced Protection Program, rather than offering a Drive-specific vault feature.

Mobile app support

OneDrive, Google Drive and Dropbox all ship official, actively updated apps for iOS and Android, and all three support automatic camera-roll backup, offline file access for pinned items, and document scanning via the phone camera. OneDrive's mobile app additionally acts as the delivery mechanism for Personal Vault and integrates with Microsoft Authenticator; Google Drive's app is the same one used across Workspace, so switching between a personal and a work/school Google account is a single tap; Dropbox's app is the most consistent across platforms feature-for-feature, since it isn't tied to bundling decisions made for a separate suite of office apps.

Which one should you actually pick

For most people already on Windows with an Office subscription, OneDrive is the path of least resistance — you're likely paying for Microsoft 365 anyway, and the 1TB Personal tier or 6TB Family tier already comes with it. For anyone deep in Gmail, Docs and Android, Google One is the equivalent default, and it's the only one of the three offering a storage-only path all the way up from 100GB to 2TB without forcing an office-suite purchase. Dropbox is worth the same $9.99/month as Google One Premium mainly if you value its sync engine, cross-platform neutrality, or need business-tier admin controls and longer recovery windows than Google or Microsoft's consumer tiers offer — but you're paying that price without getting a bundled office suite in return, which is the trade-off worth weighing before switching. If storage habits and note-taking tools are part of the same decision, our Notion vs Obsidian comparison on pricing, offline use and privacy covers similar trade-offs for documents rather than raw files.

What next

Prices and storage tiers on all three services change often enough that it's worth checking each provider's own plans page before buying, rather than relying on a fixed price months later — Google in particular has been the most active of the three at reshuffling its lineup around Gemini AI bundles in 2026. If you're trying to decide whether to spend on cloud storage or just reclaim space locally first, our guide to freeing up disk space on Windows 11 covers the local options before you commit to a subscription. Whichever service you pick, treat the free tier as a trial rather than a long-term plan: 2GB to 15GB disappears fast once phone backups and email attachments are involved.
