Proton Drive vs Google Drive: Which Cloud Storage Should You Trust?

Proton Drive and Google Drive answer the same question in opposite ways. Google Drive asks how much storage you can get for the least money, then wraps it in the best collaboration tools on the market. Proton Drive asks how little anyone else can know about your files, then charges extra for that answer. Both are good products. They are just good at different things, and picking the wrong one for your priorities is an expensive mistake to unwind later.

The short answer: pick Proton Drive if privacy is the point — end-to-end encryption on every file, file name, and piece of metadata, under Swiss law, with no content scanning. Pick Google Drive if price, collaboration, or search matters more — 15 GB included, 100 GB for $1.99 a month, and Docs and Sheets that no competitor has matched. The rest of this comparison works through the trade-offs in detail, with prices checked against both companies’ official pricing pages.

If documents rather than storage are the deciding factor, our Proton Docs vs Google Docs comparison works through the editor-level trade-offs — encryption, offline editing, AI, and migration — in detail.

The same privacy-versus-convenience trade-off shapes your schedule, too — our Proton Calendar vs Google Calendar comparison shows where encrypted scheduling wins and where Google’s booking pages still lead.

How I compared them

I checked Proton Drive’s official pricing page and Google’s Google One plans page before writing, and I treated third-party comparison pages with suspicion wherever they disagreed with those primary sources. That caution matters here: several comparison sites still describe Google’s older plan structure, and Google has since reshuffled its tiers around its AI bundles. Where I could not verify a claim on an official page — for example, exact upload speeds, which depend on your connection more than on either service — I say so instead of dressing it up as a test result. I also did not run signed-in, side-by-side upload tests, since that would require paid accounts on both services; the pricing, encryption, and feature claims below come from the vendors’ own pages and documentation.

Proton Drive vs Google Drive at a glance

Which is cheaper, Proton Drive or Google Drive?

Google Drive, and it is not close on price per gigabyte. A Google account includes 15 GB shared across Gmail, Drive, and Photos — three times Proton Drive’s included 5 GB. Google One Basic adds 100 GB for $1.99 a month, and Standard gives 200 GB for $2.99 a month, both shareable with up to five other people. Proton Drive’s Drive Plus plan costs $3.99 a month billed annually ($47.88 a year, or $4.99 month to month) for the same 200 GB. At the 200 GB tier, Proton Drive costs about a third more than Google’s Standard plan for the same space.

The price gap narrows only when you look at bundles. Proton Unlimited costs $9.99 a month billed annually and adds 500 GB of storage plus Proton Mail, VPN, Calendar, and Pass — the whole privacy suite. If you already pay for a VPN and a password manager separately, that bundle can beat buying each tool alone, and our Proton VPN vs Mullvad comparison and Proton Mail vs Tuta comparison cover those two pieces in detail. Google’s equivalent bundle logic runs the other way: its 2 TB offering is now wrapped into its AI Pro plan at $19.99 a month, which buys Gemini AI features alongside storage rather than storage alone. Verdict on price: Google Drive wins for raw gigabytes; Proton Drive only wins if you would buy the rest of the Proton suite anyway.

Which is more private, Proton Drive or Google Drive?

Proton Drive, by architecture rather than by promise. Its apps are open source, and its zero-knowledge design means files, file names, folder names, and metadata are encrypted on your device before they ever reach Proton’s servers. Proton cannot read your files, so it cannot scan them, mine them, or hand over readable content — there is nothing readable to hand over. Google Drive encrypts your files in transit and at rest, which protects them from outside attackers, but Google holds the keys. That is how Google can offer AI-powered search across your photos and documents, and it is also how it can scan for policy violations and comply with legal requests.

Jurisdiction sharpens the difference. Proton is based in Switzerland, outside the intelligence-sharing alliances that include the United States, and Swiss privacy law treats your data more protectively than US law does. Google is a US company subject to US legal process, including the CLOUD Act. None of this makes Google Drive unsafe for ordinary files — it is one of the most secure consumer storage services against outside attackers — but if your concern is the provider itself, or a government asking the provider, Proton Drive is the only one of the two that structurally cannot comply with a request for your file contents. Verdict on privacy: Proton Drive, decisively, for anyone whose files need to stay unreadable to everyone but themselves.

Which is better for working together?

Google Drive, by a wide margin, and this is the reason most people should not switch. Docs, Sheets, and Slides support live co-editing with multiple cursors, comment threads, suggestion mode, and version-by-version review, all wired into Gmail and Calendar. A team that lives in shared documents will feel the difference within a day. Proton Drive’s Docs and Sheets editors cover the basics — write, edit, share — and its shared links add two controls Google’s consumer links lack: password protection and expiry dates. Those controls matter for sending a sensitive file to one person, but they do not close the collaboration gap for a team.

Version history tells the same story from the other direction. Proton Drive Plus keeps previous file versions for 10 years, which is genuinely useful for long-running projects and accidental overwrites. Google’s consumer accounts keep prior versions for 30 days. If you are the person who overwrites a file and notices three months later, Proton Drive saves you; if you are the person co-editing a proposal with four colleagues this week, Google Drive saves you every day. Verdict on collaboration: Google Drive for teams, Proton Drive for careful solo archiving.

Which has better search and photos?

Google Drive, and this is the trade-off Proton Drive asks you to accept knowingly. Because Google can read your files, it can index them: full-text search across documents, and photo search that finds people, places, and objects without you ever tagging a single image. Proton Drive cannot do that, by design — searching file contents or recognizing faces in your photos would require the very scanning its encryption exists to prevent. You get file-name search and folder organization, and that is the deal.

Photo backup shows the same split. Google Photos backs up your camera roll into the same 15 GB (or paid) quota, with AI albums, face grouping, and editing tools built in. Proton Drive backs up photos with end-to-end encryption and no AI albums at all. If your photo library is a searchable archive you browse by person or place, Google Photos is irreplaceable. If your photo library contains scans, IDs, or client material you would rather no algorithm ever looked at, Proton Drive’s boring, unsearchable backup is the feature, not the flaw.

Which works better on your devices?

Both cover the mainstream platforms well: Windows, macOS, iOS, Android, and the web, with desktop sync apps on each. The differences show up at the edges. Linux users get a command-line Proton Drive app, with a graphical client still in development, while Google offers no official Linux desktop client at all — web access only. On mobile, both apps handle automatic photo backup, but Google’s app benefits from deep Android integration that Proton cannot match, since Google builds the operating system. If you are on Windows or macOS, treat this category as a tie; if you are on Linux, Proton Drive is the more usable of the two, even with a command-line app.

The verdict: who should pick which?

Pick Proton Drive if: your files include anything sensitive — client work, legal or medical documents, financial records, or personal material you would not want any provider to read. You get encryption that even Proton cannot undo, Swiss jurisdiction, 10-year version history on Drive Plus, and password-protected shared links. You pay more per gigabyte and give up AI search and best-in-class collaboration.

Pick Google Drive if: you collaborate constantly, you want the cheapest 100 GB or 200 GB plan, you rely on photo search, or you already live in Gmail and Google Workspace. You get the best document collaboration available, the lowest prices, and search that actually finds things — and you accept that Google holds the keys to your files.

If you want more options before deciding, our cloud storage alternatives roundup compares the wider field, and if you are building a full privacy setup rather than swapping one app, pair your choice with a messenger that matches it — see our Signal vs WhatsApp comparison. Either service here is a defensible choice; the wrong choice is picking on price alone and discovering later that the privacy or collaboration feature you needed was the one your pick deliberately left out.
