Proton Drive (Drive Plus 200 GB) review 2027

What problem does Proton Drive solve?

Proton Drive is end-to-end encrypted storage from the Proton Mail team, held under Swiss privacy law and bundled with encrypted mail, a VPN and a password manager. The problem it solves is the one that shows up when you want your whole digital life under one privacy-first roof rather than scattering files, mail and passwords across providers that can read them. The verdict from our testing is direct: as a bundle with encrypted mail and a VPN, Proton is excellent value for someone who wants their whole digital life under one privacy-first roof, while as pure storage it is slow and small. That is the trade a buyer is making, and it is worth being honest about it up front.

How did we score Proton Drive?

We scored Proton Drive across five criteria for a total of 7.8 out of 10.

• Sync speed & reliability — 19/25. We timed upload and download of the same 10 GB set over the same 100 Mbps line, three times, and checked conflict handling when two machines edited a file at once.
• Privacy & encryption — 25/25. We looked at zero-knowledge options, where data is held, what the provider can read, published audits and the jurisdiction that governs it.
• Features & sharing — 14/20. Selective sync, versioning, file recovery, link sharing with expiry and passwords, and office integration.
• Platform coverage — 9/10. Windows, macOS, Linux, iOS, Android, web and network-drive mounting.
• Value — 11/20. Cost per terabyte a year on the plan a household or small team would buy, and the lifetime options.

The shape of that scorecard tells the story: a perfect privacy result, a strong platform result, and softer marks on speed and value.

What does Proton Drive do best?

The privacy result is the headline. Proton Drive earned 25/25 on privacy and encryption, and the reasons are concrete: end-to-end encryption that covers file names and folder structure, not just file contents; Swiss jurisdiction; and open-source clients that have been audited. Those three facts together are rare in this category, and they are the reason the product sits where it does in our ranking.

The bundle is the second strength. Proton Unlimited bundles Mail, VPN, Pass and Calendar for one price, so the storage is one part of a wider privacy package rather than a standalone drive. There is also a free 5 GB tier with the same encryption, which means the privacy model is not reserved for paying customers.

How does the encryption actually work?

Zero-knowledge encryption means the provider stores your data in a form it cannot read. In practice, files are encrypted on your device before they leave it, and the keys needed to decrypt them stay with you rather than sitting on the provider's servers. That is why the provider can hold your files without being able to open them, and why file names and folder structure matter as much as contents — metadata leaks information too. Jurisdiction is the other half of the picture: Swiss privacy law governs where the data is held and what can be demanded of the provider. Proton Drive applies this by default rather than as an add-on.

What do you actually get?

The specification rows for Proton Drive are short and specific. The 2 TB a year row is listed at 119.88 USD, but the consumer bundle tops out at 500 GB, so the storage sizes are small relative to the price. Free storage is 5 GB. Our 10 GB upload test took 26 minutes. Zero-knowledge encryption is present by default. File versioning is supported. There is a Linux client. Data jurisdiction is Switzerland. There is no lifetime plan.

• 2 TB a year: 119.88 USD
• Free storage: 5 GB
• 10 GB upload (our test): 26 min
• Zero-knowledge encryption: Yes, by default
• File versioning: Yes
• Linux client: Yes
• Data jurisdiction: Switzerland
• Lifetime plan: No

How does it compare with the rivals we tested?

pCloud scored 8.7 at $99.99, with 10 GB free, a 16-minute 10 GB upload, zero-knowledge encryption available through its Crypto add-on, 30 days of versioning (365 on Extended), a Linux client, Swiss jurisdiction with optional EU servers, and a lifetime plan at 2 TB for $399. Proton is ahead on default encryption and behind on speed, free storage and the lifetime option.

Sync.com scored 8.4 at $96, with 5 GB free, a 24-minute upload, zero-knowledge encryption on everything by default, 180 days of versioning (365 on Teams), no Linux client, Canadian jurisdiction under PIPEDA, and no lifetime plan. Proton matches the default encryption and the Linux client, and is slower on upload.

Google One (Drive) scored 8.1 at $99.99, with 15 GB free, the fastest 13-minute upload we measured, no zero-knowledge encryption, 30 days or 100 versions of versioning, third-party Linux clients only, United States jurisdiction, and no lifetime plan. Proton is ahead on encryption and jurisdiction, behind on speed and free storage.

Where does Proton Drive fall short?

Speed and capacity are where it lost ground. The 10 GB upload took 26 minutes, the slowest in our test group, and storage sizes are small — 500 GB at the top of the consumer bundle. The apps are also newer and less polished than the incumbents, which shows up in day-to-day use rather than in a single benchmark. None of these are hidden costs; they are the price of the privacy model and the bundle structure.

Is Proton Drive good value?

The price summary is $119.88, and value scored 11/20. That number reflects the cost per terabyte a year on the plan a household or small team would buy, plus the absence of a lifetime option. The context that matters is the bundle: Proton Unlimited brings Mail, VPN, Pass and Calendar together for one price, so the storage line is not the whole bill. Judged as pure storage, the value is thin; judged as one part of a privacy suite, it reads differently.

Who should buy Proton Drive?

It is still right for privacy-first users who want the whole Proton suite. If you already want encrypted mail, a VPN and a password manager from one provider under Swiss jurisdiction, the storage is a natural extension of that setup and the bundle price makes sense. If you mainly want fast, large, cheap storage, the 26-minute upload and the 500 GB ceiling will frustrate you, and the rivals above are the better fit.
